I'm not using a bluetooth too much, but yesterday I have a problem and it persist.

--

I have the same on my tablet with bluetooth. All settings seems ok, bluetooth driver – seen as “Realtek Bluetooth 4.0 Adapter”, before update driver was named “Generic Bluetooth Device”. All settings set to visible.

But when I switch ON Bluetooth, there is searching informations and this searching “windows dots” for new devices, but nothing. No device could be found. And my Cube also is not visible for other devices (all set to visible as I wrote above).

Reinstalled drivers, also wireless drivers too, but nothing. How to make it working?

Wifi works fine.

Some of this problem, not only mine are here:

I'm currently using this driver: bluetooth-1.3.873.3.rar it works fine on my device, but it doesn't seem to work on every device. I wonder what could be the cause of this issue, a different hardware revision?

I tried it, but couldn't see any difference in wifi signal strength.

[MENTION=6142204]Brad D[/MENTION]

Hard to tell, only possible solution is to check the SSD in another device / using an M2 SSD adapter.

[MENTION=6912182]Abyss987[/MENTION]

If this only happens when the keyboard is connected, than it is probably intended as the USB3 port seems to share it's power with the keyboard hub.

I have installed this driver (this one from you, from link above), but it's not changing anything. I have tried also to choose a driver from list, also deleting all and instal only one, but nothing worked. Here is a screen - is in Polish, because it's my language. But I think the devices names list is important.

I can't check if it worked on main Cube i7 Windows installation (Chineese) before I've installed my own new W8.1 Pro.

How to check hardware revision.

And another question - can I backup my current BIOS, with current settings, as is?

In case, when I will try flash other one to have opportunity to back.
[Windows 8 General] Wootever:
This can only be done by the vendor, could be possible that cube uses different revisions for the Realtek WiFi/BT chip.

Yes, it's done automatically by the bios updater script, the backup is getting saved in the same folder as Flash.cmd.
[Windows 8 General] oeriel:
OK, thanks.

Above in my post I've placed some screens about this Bluetooth
[Windows 8 General] Wootever:
Just wanted to add that those are two 3.7V cells in series, which results in 7.4V.

In theory they could be easily replaced with much larger cells.

Max size: 14.5cm x 13.0cm x 4.5mm

Hi all, I have a problem. I upgrade to Windows 10 and then I installed the drivers and the update BIOS...

Now my tablet is broken. I cant do anything beacuse the tablet show me a blue screen with the error critical_process_died. Seriously I cant do anything.

I think the problem is because I updated the BIOS. Who can help me? How can I put the original BIOS to fix it?

Thanks
[Windows 8 General] Aicene:
Does it show BIOS boot screen? But if you have a blue screen then it is Windows problem. Let's go to MS site, build a bootable flash and reinstall Windows. Or at least try to fix it with it. but better install it fresh.

Please can anyone tell me how can I check/get proof that my Windows are not genuine, so that I can get refund on dispute?

I made screenshots of KMSpico activator and also of Windows Defender detecting it as threat and deleting it, but Windows still appear as genuine and activated. I know they aren't but I need a proof.

Key is visible, so maybe there is way to check key online, but I don't know where?

And did you guys mentioned in your dispute that pen wasn't Cube pen as it was advertised or you just mentioned cracked OS issue?

Please advise, I also payed for genuine OS like you guys and would like to have them in the end, or at least partial refund..

Open a command shell and enter:

slmgr -xpr

If you see volume license activated than you have a invalid version.

[MENTION=6913657]Wizher[/MENTION]

This is more or less a common error and is caused by interferences with the SSD and WiFi module, i never encountered this issue so i don't know a proper fix for it.

Error also on forum.tabletpcreview.com

Enabling Custom Resolutions

Hello

For those who might be interested like me to play some 3D games from time on the Cube I7 I noticed that there are no 16/9 resolution below 1280x720.

In fact Intel Display drivers contain a menu that allows to add/create custom resolutions.

This one was disabled on mine, maybe it is enabled on others ?

You can enable it on the Cube I7 Stylus the same way as the Surface Pro 3 with a little reg file.

When added into your registry you will be able to access the menu item in the Intel Display Properties (right click on the desktop and Display Properties).

Then click on the Display button and on the drop down arrow next to the "Display" sub category item (top left of the window).

Here a drop down list will appear and the last item should be the Custom resolution manager sub category.

picture (sorry frenchy inside :P) showing how to access the menu:

[IMG="Intel Display Driver Properties - Custom Resolutions"]http://xdaforums.com/attachment.php?attachmentid=3456749&stc=1&d=1440948949[/IMG]

[IMG="Intel Display Drivers - custom resolutions menu category"]http://xdaforums.com/attachment.php?attachmentid=3456754&stc=1&d=1440949159[/IMG]

I added 1024x600x60Hz and 800x480x60Hz though I am not sure I will be using the latter...

1024x600 allow to play Diablo 3 Reaper of Souls with around 25-35 fps (lowest graphics quality)

1280x720 only allow me to get 15-25fps which is still very playable but I really prefere smoothness over display sharpness here :)

I found the info here

Direct link to reg file: here

Oh and for those who would like to know the tablet has accepted my 128GB SanDisk Ultra MicroSD flawlessly

As the tablet is advertised to handle 32Gb sized microsd card at max on every website resellers I saw...

Hope to help

For those, who have problem with Bluetooth on Cube i7 Stylus.

On TechTablets http://techtablets.com/forums/topic/its-too-hot-battery-4500mah-bluetooth-issues/#post-10589 is a solution.

For me works installing Realtek Drivers from Lenovo.

Everything it's ok now.

Wootever, can you check now what is the problem with this? Different device/chipset?

On the Devices Management I have no change after installing this drivers. Still have Realtek Bluetooth 4.0 Adapter, v. 1.3.842.3.

Maybe is possible to extract lighter driver instead this 50 MB files.

Wifi disconnect when attaching original keyboard

I got my i7 stylus several days ago with win10 pre-installed and got the SSD upgraded to 256GB everything is working fine... but one really annoying thing is that almost every time I attach my i7 to the magnetic keyboard, there is a large chance that I have to try several times to get it stand right, meanwhile I notice the wifi gets disconnected. and sometimes even for a while, the wifi block is completely gone in the action centre. it usually takes it 30s ish to find the network again... sometimes longer than that... Just wondering are you guys experiencing the same thing?? I thought that maybe due to the magnetic... Please share your idea or fix if you ever encounter this issue :) thanks!

[Windows 8 General] Wootever:
Well, i accidentally damaged the digitizer and it seems that replacement parts aren't available, so i'm probably going to buy an Onda V919 Core M.

Driver package is most likely to receive further updates as most Core M devices are pretty similar, but i won't do bios or hardware mods/updates any longer.

Edit:

This is not to punish Cube or other device owners, but simply the result that i can't fully test new updates anymore.

this device consume much power cause of wifi module is connected by USB bus.

Thanks [MENTION=6915532]icsoft[/MENTION] for this guide.

Linux on Cube i7 Stylus:

Cube refers to Lubuntu 15.04 as installed from a x64 live desktop iso with 3.19.0-15 kernel.

You will need a USB keyboard, a USB hub and a spare USB stick 4GB or more formatted to FAT 32.

Use "Startup Disk Creator" to make your USB stick bootable and load your ubuntu ISO (i use Lubuntu).

Install from USB:

Cube USB seems to fail config on bus powered device if your USB key and keyboard draws over 200mA, to resolve this:

use powered hub, or

manuall configure USB ie. "echo -n 1 /sys/bus/usb/devices/[usbdevnum]/bConfigurationValue" or

hub that does not comply with USB spec may also work as it reports less current than it draws

WiFi Driver:

Use driver for the RTL8723BU from lwfinger on Github (https://github.com/lwfinger/rtl8723bu)and compile it on a pc that has the same kernel as the lubuntu you are installing.

To compile this you will need Git and build-essential from the repo (sudo apt-get install git build-essential)

Get the driver (git clone https://github.com/lwfinger/rtl8723bu.git)

Compile it (sudo make)

copy the compiled 8723bu.ko file to the Cube and put it in /lib/modules/3.19.0-15-generic/kernel/drivers/net/wireless

make it root owned (sudo chown root:root 8723bu.ko)

run a "depmod -a" to refresh the module list

then "modprobe 8723bu" to load the driver and your wifi should come up.

As soon as you have WiFi running, update all your software (sudo apt-get update&& sudo apt-get upgrade)​

Sound card:

The sound card is an Intel PCH (Realtek ACL283 chip)

Open Audacious and go into the settings

Audio - ALSA Output settings

Select ALC283 Analog (at bottom of list)

Mixer Device - HDA Intel PCH

Other software:

install "onboard" for an onscreen keyboard (sudo apt-get install onboard)

I found that i could not get the on-screen keyboard to work for logging into the cube.

I haven't recieved my wacom pen as yet, I will update this with more info as i get things running.​

This should be doable: replace battery cells

On the battery contacts on the protection board you can resolder cells with a similar size or if the contacts don't exactly fit, you can also solder the cables from the battery cells. Only take care at the polarisation, + is on left and - (ground) on the right of each pair.

Edit:

It's not a visible damage, i guess the touch controller itself is defect.

Edit2:

I think it's the digitizer pcb board which has damaged conducting paths caused by mechanical stress by disassembling the mainboard.

Can you simply tell me how can I sold a new battery? There are 4 plates named (from the left): B+ / VM / VM / B-

So on this direction:

B+ [+} / VM [-] / VM [+] / B- [-] ?

And 2nd - can I sold battery cables to only one side, ie. B+ and left VM and right side left empty?
[Windows 8 General] Wootever:
Yes, this is the result i got with my voltmeter.

Probably not, those cells are series-connected to reach the required 7.4V. The new cells need to be very similar to the current ones:

2x Lithium-Polymer with 3.7V and 4500mAh+ (higher rated cells should be automatically adjusted by the Gas Gauge IC: Texas Instruments BQ3060)

Creepy palm rejection

After 3 weeks on W10, I'm rolling back to W8.1 because of no palm rejection in the bottom and/or right edges of the screen (approx. 25-50px). It's makes this device not usable under W10 and with pen. There is a lot of reports regarding this bug directly to M$ on the net

I recently bought a Cube i7 Stylus 2nd hand from someone in the neighborhood, and so far I am liking the tablet.

But I have a weird issue where I can see an installer popup flash by whenever I reboot or shut down windows 10. Looks kinda weird.

Hello,

I received my Cube i7 stylus 4 days ago and everything seems so cool for me. I'm just thinking about upgrading to Win 10 (because it's win10 and it's free :D)

[Windows 8 General] Boid-man:
Sad to hear. I find new palm rejection very useful. Being able to select tools with my left hand and at the same time draw with my right. Maybe your tablet is set to left hand?

With mine, everything right of the tip of the pen should be rejecting palm, everything left of that point will accept touch from only the left hand.

After upgrade mine to windows 10 everything work better then in windows 8.1.

I don't think that you will lost something, and even more. if you not happy with windows 10 you can role to windows 8.1 in one click (it valid only for one month after the upgrade to windows 10)
[Windows 8 General] icsoft:
Make sure that when replacing Li-Po cells that you do not use smaller ones as the charging circuit is designed to charge at a safe constant current rate of 1C, that is 1 x the mAh rating of the battery, ie if the battery is 4000mAh it will charge at 4 amps.

Our 12v 2.5a power supply is capable of supplying 7.5 amps at 4v and the Li-Po battery will charge at anywhere between 3.6 to 4.2v, so unless you know the current rating of the charging circuit, be aware that changing the battery isn't as simple as it looks.
[Windows 8 General] Wootever:
[MENTION=6915532]icsoft[/MENTION]

That's what i thought, my intend was to increase the capacity by replacing the battery cells.

Other than measuring with a voltmeter i have no way to verify any battery data, this is the gas gauge manual but it's unfortunately controlled by the EC which has no public available documentation. The chip itself is probably an custom-built model for Core M processors (ITE IT8110E).

Edit:

The ACPI BAT0 reads the Designed Capacity from the Embedded Control on offset 0x80. The battery information just multiplies it with 10 and lists it at 43.000mWh.

Method (_BIF, 0, NotSerialized) // _BIF: Battery Information
{
Name (BPKG, Package (0x0D)
{
[...]
Index (BPKG, One) = (B1DC * 0x0A)

The battery status lists the present rate at 8~9 mWh, it is multiplied with the default battery voltage of 7.4V

Local0 = (B1CR * B1FV)
Local0 = (Local0 / 0x03E8)
Index (PKG1, One) = Local0

The default capacity of 43.000mWh is probably 4300mAh, the current rate would be ~1.15A, so i guess it's 4,255A per cell

Ater upgrading to W10, my auto rotation of display doesn't work, which driver should I update?

The screen doesn't rotate at all when I turn the tablet.
[Windows 8 General] icsoft:
My handy dandy linux battery app reports the current capacity of my battery as 5864mAh at 7.4v (5810mAh reported by the battery), so this is obviously 2 x 3.7v cells in series at 5810mAh each. (series doubles the voltage, whereas parallel doubles the capacity)

To determine the charging circuit constant current rate, you will need to put a multimeter that can handle up to 6 amps in series with one of the battery cells as they should be separately connected. The batteries should be being charged at 5.8 amps or lower.

The battery must be around 50% charge to get an accurate reading as the charging circuit will go into constant voltage mode (4.2v per cell) if the battery has too much charge.

Note: this is what my battery app reported, that is usually read from the BIOS, my calculations were based off those figures, the actual standard battery size is 4500mAh on this device.

On a 4500mAh LiPo cell 4.5 amps is the maximum charge current, if you do not want to destroy your cell.

It is not an USB cable,

The Anker Astro Pro 2 has a 12V DC output (round plug).

I will not work with an USB cable. USB is 5 V. The only thing you can do is by a USB to 12 V step up converter and charge with this the power bank. Even with this step up converter you cannot charge the tablet directly as the charging current is way too small. Charging the power bank works. However it takes ages ;(
