Yes.this is correct.I have also tried air ii dual boot bios with the hope it will work as the win only but no luck.The conclusion is that dual boot bios has issues.That makes me wonder about onda dual boot implementation if it has the same issues.

As for GPS someone posted that you can manually add as legacy device the GPS but have not tested it.

So at this point we need to choose either Android or Windows for a stable run?
[Teclast X98 Air 3G] grigoris_a:
If you mainly use android you can have dual boot.Windows will be stable.But if your primary OS will be Windows then dual boot is not an option.Unless you not mind a drain of 3-7% /hour

what about screen refresh rate in Windows? 48 hz or 60 hz?

I want to ask if anybody know how to install flash player on this tablet? I am on Mirek 190 rom and c6j6 model. Thanks
[Teclast X98 Air 3G] Petepe10:
Well, not exactly the point. 1A should be enough when powered off to charge (slowly). 1A is not enough under use. Ignoring losses (incorrect since tab gets hot but as a start) :

If tab battery is 8000 mAh it can deliver 8 hrs of 1A. Normal use is less than 8 hrs, so it consumes more than 1A. So a 1A charger can not keep up with use and battery drains. If you look in my previous post you can see how to check it. Android only though.

About chargers: a good one will maintain voltage up to the specified current, and even overloading will not happen as the current will not increase further or it will stop. A bad one will indeed drop in voltage, sometimes even well before the specified current. Have a peek at http://www.appleclubeindhoven.nl/apples_en_peren.html and http://www.appleclubeindhoven.nl/apples_en_peren-2.html for a comparison of cheap Apple lookalikes, in Dutch but the figures are clear. Plus some can be dangerous too. Not a bad idea to invest in a good one. The teclast seems to work ok., but durability we don't know yet of course.

Can you please do something to make sure we are having the same issue?

1. Boot into Windows

2. Press power button

3. Touch the screen right after

4. Does the screen turn on?

Because if it does that means the controller that is used for connected standby is broken. For connected standby to work the screen may not wake the tablet. Android requires all components to be compatible with the android version of connected standby, therefore it turns of the touch screen because it is no longer compatible. While Windows is more relaxed. I am working on a fix that will re-calibrate the controller.

When I use the standard Teclast charger I usually get "Throttling brightness due to thermal event". I don't think this is a good sign and may end up by frying the tablet. What do you think? Do you also get this notification when using the standard charger?

Hi guys, since yesterday I'm owner of tablet Teclast X98 Air II, model series HG8N with dualboot. But I found one problem when power supply is plugged into tablet Windows is allone shutting down. I don't know where, but I read that's problem with Bing version of Windows and reinstallation to Windows 8.1 Pro should solve this issue. I would like to know if reinstallation will help, because I don't want loss warrancy if it's HW issue. Thanks Oli

[Teclast X98 Air 3G] Jote:
What i see happening here is the same that with a too long and bad quality USB cable. Voltage drops when too much current is drawn and the device throttles and never recovers until cable is unplugged. Even though recharging is "smart", it usually doesn't even try to recover and take more current again.
[Teclast X98 Air 3G] supercowz:
after lot mail and fight ....

Dear Philippe julien, this is Echo.

Really sorry that you received so many tablets with problem.

GPU issue on X98 seires has bring us a lot of trouble to us. Especially that at the beginning we didn't know about it and only got some feedback. And Teclast keep silence and they didn't admit at the beginning.

Now they have released a file to fix it but in fact, we are not happy with Teclast's solution, neither.

The APK file can make the tablet run games smoothly but it cannot fix the issue completely.

Because your experience of games will drop down a lot. Also as you said, it cannot solve problem under Windows.

Wish you know, after the APK available, my manager has talked to Aliexpress dispute team specified about this. And they tell us that under this case, they won't let seller refund money, because no one can promise that all games can run on a tablet, and also Teclast had offer help of the issue.

We will still refund you $30. Because you are an old customer. And also we know it deeply that the solution from Teclast is only fudge trying to avoid responsibility. They won't give us any compensation for the issued batch. But you bought the tablet from us. So it's our job to make you satisfied. $30 must be your deadline. We really apprieciate your kindness.

Best regards,

Echo

If Teclast can slam the door on their authorized sellers, then why wont they abandon their customers. This is the risk we took when going with a Chinese brand and that is exactly we got.
[Teclast X98 Air 3G] j.jusko:
I am not sure if 1A is enough. And be careful because I saw on another forum so many burned chargers similar to this on your link.
[Teclast X98 Air 3G] kosrica:
If the original charger which came with the tablet is not ok, shouldn't be removed from the first page where the charging possibilities are listed? Or at least a disclaimer should be added, something like it may burn your tablet...

Any news of 3D freeze issue on windows?

Anyone have the bios file for dual Boot with the options available for disable turbo bios?

Thanks in advance.
[Teclast X98 Air 3G] vpx:
Hello, I still believe, that battery drain in Windows could be solved by software.

When you use OpenPowerCfg, you can see many settings, that are derived from BIOS to PowerCfg control panel (not visisble), but they are present in registry. When I something change, it goes back again and new value is not remembered, but I think, if I will write this into registry, it should be remembered (or write to registry after every restart).

There are such values e.g. for how many minutes will stay tablet in sleep mode, before going to hibernation etc.

From these knowledges I think, that some powerscheme properties are derived from BIOS and may be different for dual-boot and single boot BIOS.

I exported my powershceme settings, but need for comparison exported powerscheme settings from "not drained" Teclast.

Could anybody export it for me ? Detailed instructions I wrote here 2 weeks ago, if you can't find it, I will repost it.

Thanks
[Teclast X98 Air 3G] Petepe10:
The tablet indeed gets warmer, but it depends on the load current and tablet charging circuitry and its adaptive behaviour, not the quality of the charger, it does what it is supposed to do, deliver 2 A or so. Tablet also gets warm with an ipad charger. Whether this is bad and throttling is dangerous I do not know. No harm of course using a good 1A charger while not using it.

[Teclast X98 Air 3G] grigoris_a:
I find this impossible.Because without changing anything in power scheme and by changing bios the drain disappears.The only thing we can do is capture a wpa trace( https://msdn.microsoft.com/en-us/library/windows/hardware/dn495340(v=vs.85).aspx) to pinpoint the cause since with dual boot bios sleepstudy reports no possible offenders for the drain.

But I could not find PowerManagement_Profile.wprp mentioned in Microsoft guide to do it.

Please read the first post.It is mentioned numerous times.In order to access dual boot menu you have to keep vol up pressed when you press power button to boot.

You don't have to change your bios.And since you already had dual boot system I believe that you now have only one OS installed(pay attention to wimpart.txt or flash.xml depending on what you are flashing because those files will either wipe the whole disk or prepare it for dual boot)

I think it is good create basic battery report based on http://www.eightforums.com/tutorials/31440-battery-usage-report-generate-windows-8-a.html and send this file to them

I suppose, that there are marked start and end of sleep (suspended), but you can describe it under picture too (sleep was form 1pm to 8pm, you can see battery drain from 82 to 50 percent in 7 hours in this graph).

Hi, I found where is a problem:

- Windows cannot use CPU frequence 2.16GHz, it's keeping still on 1.33GHz and it cause that

- temperature is growing to 88-90 °C and then OS is shutting down

Solve somebody this issue, how to use also 2.16GHz in Windows?
[Teclast X98 Air 3G] Petepe10:
Hmm, do you think it is wise to use the high frequency if it is already overheating? I assume it is throttling CPU because of temperature and then shutting down.

Seems to me that you have a tablet with a problem in charging/overheating, and probably you should return it.

New update via Teclast OTA

See screenshot. Download is slow.
[Teclast X98 Air 3G] fearxl:
what's new?
[Teclast X98 Air 3G] grigoris_a:
You will provide them with a sleep study report(see attached pic) and Microsoft explanation as follows

""RED indicates at least one of the following:

The DRIPS rate is < 80 percent.

The drain rate is >= 1 percent per hour. (If the drain rate is >= 1 percent per hour, the connected standby battery life will be at most four days.)

ORANGE indicates at least one of the following:

The DRIPS rate is between 80 and 94 percent.

The drain rate is between 0.333 and 1 percent. (If the drain rate is under 0.333 percent, the platform will achieve 12+ days battery life in connected standby.)

GREEN indicates all other cases.

By design, some sessions are active (red rows). But most sessions can be expected to reflect low activity and low power (green). The color scheme is designed to make potential high-drain sessions easy to identify. You should be most concerned about long sessions (of several hours) that show high sustained battery drain—these sessions have the most impact on the battery

The example in the following image shows that the connected standby session had very high drain, but that no offender was over ten percent active. The deepest runtime idle platform state (DRIPS) histogram shows wake-up patterns. Typical low-power sessions have sleep time intervals that are close to 32 seconds, but this histogram shows that the sleep time interval is less than one second (closer to 512 milliseconds). This type of activity implies that frequent interrupts or some other hardware component causes the system to stay awake, which results in poor battery life.""

I am attaching a pic for your reference.With 1 is the color that should be Green or orange at best and number 2 are the possible causes for the drain if the 1 is red.As you see in my pic the row 1 is red and have no possible offenders(2 are all green).

Also me DRIPS rate is at 95%.So why the drain.It's because of the bios.

What's that? An official update from teclast? If so for which tablet version?
[Teclast X98 Air 3G] SUMMERBREEZE:
If i understand you well, If ROW 1 is RED, It means there is deffinetely a battery drain but in ROW 2 every line is GREEN and we dont see whats causing the battery drain YES? its somewhere hidden ?
[Teclast X98 Air 3G] grigoris_a:
Correct.Also DRIPS IS 95% meaning that the session should be marked as Green.The only way to find out is capture a WPA(Windows performance analyzer) session and find the cause of drain.

But I find no reason for doing that because this happens for all sessions not just one or two and this thing it's fixed with the air 2 bios.So it's clear that dual boot bios keeps something active that drains the battery.

[Teclast X98 Air 3G] grigoris_a:
Let's clear things up.Bios flashing does not modify your emmc disk.So if you have now both android and Windows they will remain that way.If you flash a Windows only bios you will be able to access only Windows.If you flash an android only bios you will be able to access only android.But the other OS WILL NOT GET LOST.So since your Windows work fine boot to Windows and flash win only bios to make a win only tablet.Then boot to Windows again and flash the dual boot bios.

Here is the link for a win only bios http://techtablets.com/download/teclast/x98_air_3g/bios_files/X98_Air_II.zip
