[MENTION=8115234]DoubleStuff[/MENTION],

Since we are discussing battery capacity, I was reading back through this thread and ran across post #17 where HPTP's capacity rating would equal the capacity/size of 6612mAh. So how did all that get lost from the discussion? Even one of the screenshots shows 6612mAh. So, did some TouchPads have 6612 mAh batteries too? He pointed that out, not me.
[TouchPad General] DoubleStuff:
All my image references are to this POST #17

p.s smithy I was all over this in POST #60 what took you so long. LOL

even though I touched on this in POST #60 we will have to see what [MENTION=8005714]HP_TOUCHPAD[/MENTION] says about it because even if I dismiss the 6612 mAh number as a fake manufactures ratings from a rogue Dr. Battery app reading from the kernal, this cannot explain the capacity using the novacom command on WebOS:

novacom -t open tty://

battery status

battery present

voltage: 4113840

percentage: 100

current: -861562

capacity: 6483200 which is 6483 mAh

Notice the capacity is 6483 mAh from the novacom command image 6

According to Dr. Battery the capacity is 6457 mAh from image 1

According to Dr. Battery the capacity is 6452 mAh from image 3

The key question is how can Novacom say the capacity is 6483 mAh after 8 years, when the capacity of a new battery is 6000 mAh of all HP TOUCHPADs??.....That is the $64,000 question.

But now I l know were HP_TOUCHPAD got the 5% rule, look at the manufactures rating in image 5 I have also attached a zoom of it and circle it in RED.

....

..

.
[TouchPad General] smithylovestouchpad:
There you go, we have a whole new discussion to debate. :eek:

And I don't think the 5% mark up rule can explain away this one. Oh wait, I still have not seen any corroborating information to support that except hearsay.
[TouchPad General] DoubleStuff:
Well we are in a thread loop now because my POST #60 was answered by your POST #61 Where you answered thusly:

Regardless, I am not going to revert back to WebOS to find out. HPTP can just drop in here and explain himself. -SmithyLovesTouchpad on 11/29/2019

And looking at further posts after that, I posted a picture about a 6000 mAh battery, you and HP_TOUCHPAD

got caught in a little "sacred devil" argument, and my question of post #60 was never answered because everybody

got sided tracked.

So the bottomline this battery thread, to put it simply, well...."This cake is baked", "The rodeo has been run", "We beat this thread like a dead horse." QED.
[TouchPad General] smithylovestouchpad:
If I didn't know better, I would think you were trying to spoil my fun. And so many questions left unanswered. Guess we'll have to wait for the next great innovation. I think this goose is cooked. See ya on the flip side.

I have 2.5v reading in this battery pack (see pic).

Is one cell dead?

Can I revive it with a lipo charger?

anyone can give an advice.

Thanks
[TouchPad General] HP_TOUCHPAD:
I will suggest to get the actual reading from the A6 controller, it will show the true battery capacity.

1. Charge the Tablet to 100 % in Android, after it reach 100 % leave it charging for 24 hours, yes there is more to charge that is not been display.

2. Reboot the Tablet and select WebOS Recovery.

3. Connect the tablet to a PC with the novacom drivers then enter the following command in a terminal:

novacom -t open tty://

chg battery

It will display the true capacity charge at 100 %.
[TouchPad General] pas7771:
Taking it apart was my last resort as the Tablet won't charge at all, I have the original charger and a touchstone.

I tried all possible way to charge. I had a Battery with a ? in it but no luck..

USB doesn't show, so I can't do the battery reading.

I thought the battery cell are below charging point for the A6 controller and maybe it need a little boost.

the 2 cell are fine, not puffy.

Any idea?

Thanks.
[TouchPad General] HP_TOUCHPAD:
Then the battery got depleted, completely discharge. It does look fine ( flat ).

It will take long time to start charging again, possibly like a week.

Using the charger, better the wireless charge it in a room temperature of 80 F to 90 F, it takes longer on cold temperature. The battery needs to wake up and charge again.

Take a look here for the battery symbols:

https://xdaforums.com/hp-touchpad/general/hp-touchpad-novacom-repair-android-t3960435
[TouchPad General] pas7771:
Thanks a lot.

Is it possible, that maybe a bricked or faulty A6 controller can't charge the battery?

In the Picture, since it's all apart do you think I can give it a boost charge with a Lipo B6 charger

attaching the clamp in the + and - ?
[TouchPad General] HP_TOUCHPAD:
No the A6 controller does not get bricked, if a battery symbol show on the screen the Tablet is working and not brick.

Lithium batteries can never be completely discharge, it has nothing to do with the Tablet.

Always keep the Tablet charging, when full it will stop charging and maintain the battery for ever.

Only charge the battery with the authentic HP charger, if anything else is applied it will damage the electronics. There is no quick shortcut, if the Tablet has not been use for years do not expect to come back working in a minute.
[TouchPad General] pas7771:
Yes you right.

Maybe one other solution is to unsold one terminal like the + one and bypass the A6 controller to charge the pack with a balanced lipo charger then when fully charged

resold back together?
[TouchPad General] HP_TOUCHPAD:
I do not advise destroying a battery. It only takes time with factory charger, the simple and non-destructive process is to do intermittent charging. One minute plug to electrical wall and one minute off, do that 10 times once in a while when is charging to increase the amount of electricity (mini burst).
[TouchPad General] pas7771:
I followed your advice and put the touchpad in normal charge..

nothing is connected only the motherboard, battery pack and usb module. is that ok for charging?

Also there is a soft button in the picture. what does it do?

Thanks for all your inputs HP_TOUCHPAD

Best.
[TouchPad General] HP_TOUCHPAD:
It is very important to connect the screen with the Home Button working.

The screen and Home Button gives indication of what is going on.

At this moment there is no way of knowing what is going on.

Make sure the screen gets connected properly.

There should not be any soft button or anything to press inside.
[TouchPad General] pas7771:
OK, will do.

Thanks again.. in a week or more I will let you know
[TouchPad General] pas7771:
Hello TOUCHPAD,

do you know the 2 cables or pins that do the actual charging in the A6 plug ?
[TouchPad General] HP_TOUCHPAD:
Do I do not, never had to modified the charger for the battery to charge.
[TouchPad General] pas7771:
Hello [MENTION=8005714]HP_TOUCHPAD[/MENTION]

Unfortunately, charging with the usb didn't work.. the battery was too low or the A6 board is not recharging

I took apart the A6 board and unsold the battery.

I had good success charging with a B6 Lipo charger and gave a good 3.5v

I soldered back together put the touchpad together and did a tpdebrick

but it failed at copy A6 flies

see my post in this thread https://xdaforums.com/showthread.php?p=83126473#post83126473

If you have any Idea how to flash the A6 .. the toolbox don't find the device, I tried that.
[TouchPad General] HP_TOUCHPAD:
It does not matter what advice I will post, everyone will try to look for a quick magic way and never is the user's fault, but the Tablet or the A6 controller.

Make sure all components are perfectly connected otherwise with no info on the screen the Tablet can boot and there is no sign to tell if is ON or OFF.
[TouchPad General] pas7771:
Hello,

When I got this touchpad the battery 1/2 way and the touchscreen frozen.I suppose I charged it and let it sit overnight to work on it the next day.

well the next day it was black and no sign of life, no battery symbol at all.

I try the tpdebrick-v004 without success for A6 firmware.

when I decided to take it apart to really check the battery because it wasn't recharging. no mater what I did I let it on the charger for days, I did the trick charge.

nothing..

But the battery is in good shape and I did charge it on a lipo charger successfully, but I soon as it connected to the touchpad, it will discharge and the battery won't recharge at all

user fault or A6 controller you tell me??

a lot of people had this as well good battery that never recharge. and as far as tpdebrick-v004, lot of people brought new battery replacement to find out it wasn't the problem.

I originally brought 2 of them.. One is still in my hand and running fine because I take good care of it. the second I gave to my mother in law beautifully working and I got it back the way it is... I can blame user error.
[TouchPad General] HP_TOUCHPAD:
As mentioned the Tablets are not error free and prone to defects. I do have one that it will discharge when is completely off. It could take a week, but for sore reason all the charge is gone, it does charges fine and also wake up. It happened today, it was not responding but after plugin the charger the home button lights moves side to side and then the low battery symbol until it boots.

The tablet can be use for parts or you could fine a used one and make one from the two.

Take a look at this post, it may help you finding out the true health battery status of the other ones.

[TouchPad General] pas7771:
The tablet was frozen in android home screen.. unresponsive. when i got it.

no moboot or recovery screen possible. only tpdebrick did run for a while then aborted. then no battery charge.

At this point I will try another lipo battery charge and a tpdebrick. If this don't work I might look into the A6 controller to see if there is a way to program it directly.

Otherwise it's spare parts.

Thanks HP_TOUCHPAD for all your help.
[TouchPad General] HP_TOUCHPAD:
If any Tablet freeze then it must be hard-reset by pressing at the same time the following buttons ( Power, Volume (up) key ( to the right ) and Home button. All three must be press until it reboots.

Nothing can be done if the tablet is frozen, for any troubleshooting the Tablet must be place into WebOS Recovery Mode ( BIG white USB Symbol. )

The Tablet should have been hard reset and then charge, that could have been the proper way. Doing anything while the Tablet is frozen will do nothing.

The A6 controller is attached to the Battery, all that is well document on this thread with images. Replacing the Battery also replace the A6 chip.

If you have other Tablets, the proper way to trouble shoot is by replacing one component at a time and making sure that nothing gets damage.

You are welcome and have fun learning the inside of the Tablet !

[TouchPad General] DoubleStuff:
So I know of 4 ways to "power off" a hp touchpad.

1) Press the Power button, this is just turns off the touchpad, and can be turned on with pressing power button again.

2) The 3 finger goodbye: Power/VolumeCloseToPower/Home - this puts the touchpad into a shutdown mode.

3) on Moboot screen there is a "shutdown" selection, this puts the touchpad into a shutdown mode.

4) @HP_TOUCHPAD has a PowerOFF.zip to flash, this put the touchpad into a shutdown mode.

So what is the difference in efficient hibernation between methods 2, 3 and 4 ?, I thought they are same, that the touchpad

can be fully charged at 100% and stay nicely hibernating for 6 months or more, with methods 2, 3 or 4.

P.S I have seen my touchpads come on when in method #1, but never come back on to 2 or 3.

Please advise.
[TouchPad General] HP_TOUCHPAD:
Power button works only while Android or WebOS is running, it will bring a menu to select the next action (Restart, shutdown, Recovery)

The Tablet will also turn on by connecting to USB charging, PC or wireless charging.

This is a HARD RESET, it will not do a proper shutdown of Android or WebOS but abruptly kills electricity from the battery ( like unplugging a PC from the wall outlet.

Shutdown the moboot menu, then stays OFF.

PowerOFF creates an entry in the moboot menu to PowerOFF, because some Tablets do wake up or turn on by themselves and if it boots to Android or Recovery the battery will get drain. PowerOFF is activated as a default, making it to boot into a partial TWRP recovery that turn off the tablet --- Power OFF

Shutdown is the process of all Operating System to terminate all running software properly and prevent data corruption.

Shutdown writes all information from RAM into disk, then sends the signal to hardware for power OFF.

Hibernation is when information from RAM is place in internal storage and goes into sleep, saving more electricity that sleep because RAM is not active. In Sleep mode RAM is active and that is how the Tablet works in sleep mode, but not in hibernation.

If the Tablet is going to be place in storage, it needs to be totally OFF, by doing a shutdown from Android, WebOS, Recovery or moboot.

Not by just pressing the Power key, that is placing the Tablet into Sleep mode or standby and is not going to last long.

The battery is affected by ambient temperature and will discharge faster in the cold.

For the battery to last, it can not get discharge, the best way to keep it alive is to put the tablet to some use and connected to a charger all time. It can be any charger as long as is running and charging. The onboard battery chip will maintain it.
[TouchPad General] DoubleStuff:
OK now this is good information: First that the HARD RESET is not really a shutdown, but just kills the power from the battery like unplugging a cord from a PC. And secondly that the moboot "shutdown" is a proper shutdown of processes, and sends an power OFF signal to the hardware. So as per the POWER OFF zip, lets give example:

Lets say I have two touchpads, in which from moboot screen I select "SHUTDOWN" on both of them. And for argument sake lets say the "gremlin" turns them on twice a week. One hp touchpad #1 has your POWEROFF in moboot, and the other #2 does not.

1) When touchpad #1 with POWER OFF is turned on by gremlin, it will then SHUTDOWN again with POWEROFF default.

2) When touchpad #2 without POWER OFF, it turned on by gremlin, it will just go into sleep mode after 1 minute default. Thus now it will drain battery more than touchpad #1

Key question, when your POWER OFF gets run by default in the MoBoot menu, is it the same as a "SHUTDOWN"?

in that it sends a signal to the hardware to power OFF.

One more question, remember I stored my tablets in my closet for 4 years without touching them, if I had installed the POWER OFF as default in the moboot, would my tablets still have been in the same state, that is with depleted battery?
[TouchPad General] HP_TOUCHPAD:
PowerOFF is a basic TWRP Recovery that boots with no interface that send the signal to the CPU to shut down and properly place the Tablet OFF just like moboot or Android does.

1.) The Tablet is a mobile device that the intent is to be ON all the time and charging.

For some reason, it turns on by itself, unexpectably. Once the gremlin boots it up, it will go to moboot menu and there is either Recovery or Android then it will stay on until the battery dies, there will be no second boot.

Yes, PowerOFF is set as default in the moboot menu. It boots then it turns OFF, next time the gremlin comes around, the same cycle happens but is not constantly. The gremlin is not that persistent.

The Tablet will boot into moboot menu, there is no sleep mode in moboot or TWRP recovery. In Android, the Tablet screen goes dark and the CPU idles around 300 and Wi-Fi can turn off depends on user's setting, but Tablet is breathing and alive!

Yes, is the same term use and process on PC, Shutdown and then goes OFF. I will say Shutdown is the process, the Operating System displays to the user to wait until it properly terminate all process and write info to disk, when done the system will PowerOFF.

No, 4 years is too long of a time and the batteries will be depleted even if remove from the Tablet.

Lithium batteries works by chemical reaction, and it affects any device that use it.

Electric vehicles use Lithium at the moment and the same problems, with cold charging issues and having less driving range during winter season, are all problems that HP Touchpad owners had during the years of usage. Everyone blamed the Tablet, but is the nature of the Lithium batteries.

I will say to plug in every 3 month to keep the battery charge.

back in Nov 2019 I posted this in this thread Post #49

https://xdaforums.com/t/hp-touchpad-poweroff-prevents-battery-drain.4002265/page-3#post-81037563

Essentially giving the battery capacity with the command:

novacom -t open tty://

battery status

All 3 tables have model number: FB359UA#ABA ( NOV 2019 )

tablet 1 ( with 2 cracks in the back )====4419200

tablet 2 ( with a smooth back )=======5147200

tablet 3 ( with a crack in front )=======5068800

Then in Post #71 ( still year 2019 ) this was said:

HP_TOUCHPAD said, "By the way, any physical damage anywhere on the Tablet does not affect the Battery life or performance unless is a button that got damage."

DoubleStuff replied, "Yes I know damage to tablet don't affect battery life, but I name my tablets by unique exterior markings, because lets say 10 years from now I want to check this thread again, and see my old capacities. Now I now what they are for tablets with "smooth back", "cracks in back" and "crack in front" as long as I don't damage them more! LOL

now fast forward to Current Jan 2024:

Well its has not been 10 years as my post above predicted, but its been 4+ years. So I still have the 3 tablets I named

"2 cracks in back", "smooth back" and "crack in front" and their capacities actually increased!!??

See attached comparison pictures. from Nov 2019 to Jan 2024

These 3 hp touchpads, were put in shutdown mode via moboot, and stored one on top of another for 4+ years in a dark room temperature closet. I would think by the 2nd law of thermodynamics that batteries left to themselves with no input of energy will always deteriorate, and capacity would decrease.

What kind of comments or analysis does @HP_TOUCHPAD think about that, see attachments.
[TouchPad General] HP_TOUCHPAD:
This is my update on my original HP Touchpad from the fire sale listed on this post:

https://xdaforums.com/t/hp-touchpad-poweroff-prevents-battery-drain.4002265/#post-80993173

After I saw @DoubleStuff posting, I remembered that I had to check on that Tablet, I think that it was less than 6 months from the last charge. The battery was dead, the Home key started the dance after being place in the wireless charger. I wanted to test the Volume Key tape experiment, so I did it. But the message "Please release Key" came up on the screen and did not go into Recovery Mode.

Using another Tablet with a dead battery, I place the tape on volume key, but this time before connecting to charge.

It worked, from the battery icon symbol it changed to Recovery Mode, big USB symbol.

** To set the Tablet in Recovery mode with a broken Home key and dead battery.**

Place tape first to hold the Volume UP key (closer to power) and then connect to charger.

Tablet will show the battery symbol, after getting some charge, it will show the USB symbol (Recovery mode)

The attached screenshots were taken using the app Dr.Battery in WebOS. This app gets the information from the battery chip, in the same way as using the command novacom -t open tty:// battery status.

After It was charged to 100%

Then the next day:

Later on the same day:

Then the capacity dropped:

Information using the novacom command:

Even if the Tablet shows that is charged 100%, the capacity will change. This could be the way the battery controller works while measuring the resistance of the cells. Capacity can be increase by doing intermittent charging.

Could the battery last another 10 or 20 years?

I do not see why not, as long as it is kept charged, indoors in a room temperature that a human can survive.
[TouchPad General] DoubleStuff:
Thank you @HP_TOUCHPAD for giving your analysis on the increasing battery capacity....

Volume Up/Tape/USB symbol:

And for your discovery that you have to place the "tape", now for me "rubber band" on the hp touchpad before BEFORE

you plug it in to the charger. I have done this operation 4 times now.

1) my first time I must have put tape on before I connected the charger, because I received the USB symbol, but I was not there live, and I falsely assumed that the moboot menu came up and it scrolled to WebOS recovery.

2) my 2nd time, it went into Android, and I was confused as to why, "most likely I put tape on while it was charging but low battery icon was showing", again I was not there live.

3) my 3rd time, I actually placed a video recorder so I could watch what the "gremlins" did while I was not in the room.

and replaying the video footage, I saw the moboot screen booting into Android, again I must have put tape on at the wrong time.

4) Last night after reading your message about "put tape on before connecting to charger", I used a new "Rubber Band" method since "sticky stuff" was accumulating on my button, and I followed the method "depress volume up key first, then connect the charger" and I was there live to see it change to USB symbol ( and no moboot ) screen.

I call this method the "Goldilocks Rubber Band" method.....because rubber band must be "not too tight, and not too loose, but just right" - Goldilocks circa 1837

[Moto G6 Questions & Answers] rosjo99:
Hello,

my Moto G6 is stuck during the boot-up. It goes to the phase where the background colors switch but after a while goes back to the blue android screen, followed by the switching colors again and so on. I have recently installed a security update and have already tried wiping the cache partition. I don't want to do a factory reset right now, as I have a lot of data on the phone that I need. Does anyone have an idea how I can recover the data? One reason why this might happen is that the storage was close to maxed out. I had the same issue yesterday and after a while letting it try to reboot it did work fine actually, but this time it has been stuck for hours and no progress. What might complicate the issue is that I currently don't have access to a Windows PC, only Mac.

Best,
