Potential solutions to some Hi10 Issues

[Laura]

don’t do the freezer thing. it will just make moisture inside the tablet condensate on the board and damage stuff

[kravmama1]

Yes. Thank you for pointing that out. There is a risk of condensation damage with the freezer thing. If you read the forum that I cited, the poster tried to mitigate the condensation issue. The poster was desperate and the tablet was already deemed “dead. ” It worked for that person and a few others on the forum.  But use that freezer method at your own risk!

I have edited my original post to include that warning.

 

Another thing to try is if the battery seems dead and charging light won’t turn on, trickle charge for an hour via USB port of computer and see if the charging light starts to blink at that point. If so, finish charging using a wall charger.

Hey , You SAVED my hi10 !!!

Created this post about how it is working now

http://techtablets.com/forum/topic/chuwi-hi10-cannot-power-potentially-solved/

Credited you! hope you don’t mind!

[kravmama1]

Glad to hear that your hi10 is working again! That means that there is hope for other hi10 users, and that some issues may be Windows related and not due to a bad tablet.

I figured that if Surface pro users were having the same issues, then it may be an OS issue, since that is a high end tablet.

I tried to solve the black screen issue using the described steps and a whole lot more, unfortunately it did not work 🙁

Additional suggestions for black screen issue

For some owners, the issue is hardware, the tablet may be defective. For others, it is software and can potentially be fixed. If there is charge in the battery, then what may be happening is that the tablet may be going into sleep mode and won’t wake up. I am posting a link that suggests that updating a driver may fix the problem. Four possible solutions are listed in detail. It’s worth a read and a try.

Do you have charge in your battery? If so, have you tried completely draining the battery, then recharging, then power button?

[Conscript]

I do not know if the battery is charged. When I connect it to a charger, the charging light does not light up.

I haven’t tried draining it yet, so I might try that.

Also, when I turn it on, I can hear the tablet chip resonating (modem like sounds) when I put my ear very near it. It then stops at the same time, each time. I dont know if this means the battery is almost empty, or there is some other issue.

First, don’t try to boot up on low battery. That can make it crash. Go ahead and connect to charger. To see if there is charge in the battery, connect a device with a light to one of the USB ports. If the device lights up, the battery is not dead.  Keep it on the charger for a couple hours before attempting to boot up.

On hi12 forums, some had success with docking the tablet in its docking keyboard, if you have one. If not, try attaching an external USB keyboard and pressing CTRL+ALT+DEL. You may have to press those keys a couple times then try to long press the power button. Then short press power button to turn on.

If you eventually wake up the tablet, please let us know what worked.

[kravmama1]

OK. After all my warnings that going into software-triggered (non-power button push) sleep state can trigger the black screen problem, I managed to cause the black screen on my tablet by pushing a hotkey on my wireless keyboard that triggered sleep and sent it into a coma. Given all my research, I didn’t panic. I tried pressing CTL+ALT+DEL a couple of times, then long press power button followed by short press. Then tried ESC key and  other random keys on the keyboard. Tried power+ volume up button. I connected to charger and no LED light. I removed the charger and connected a USB keyboard and pressed CTL+ALT+DEL a couple times, then long press on the power button for at least 30 seconds. Reconnected charger and LED charging light was blinking. Pressed power button and also power+volume up , don’t remember which first. Tablet started to boot with Chuwi logo then went to black screen. LED charging light still blinking. Did more research and read that sometimes Windows 10 will cause lockscreen to be black on startup. Solution: press CTRL then enter your PIN/password. After doing that, I long press power to shut down, then short press to start up. Tablet booted up and working normal again. From now on, will avoid putting tablet in sleep mode.

UPDATE TO BLACK SCREEN ISSUE

This applies to tablets that have charge in battery, but has black screen.

There seems to be 2 situations.

1. Screen is black, can’t shut down or boot up.
2. Tablet boots up to black screen.

Screen black and won’t shutdown/boot up

This is known to occur on several different tablets/laptops after update to Windows 10. This is most commonly associated with the tablet going into sleep mode and not waking up. This is associated with issues with drivers incompatible with Windows 10. To recover the tablet, one must attempt a forced shutdown, then reboot. Here are some suggested methods (each number is a different method) and explanation of what is happening:

1. Hold power button for 30 seconds or longer (this attempts forced shutdown). Let it sit for 15 seconds. (this allows it to run any shutdown routine and achieve a full powered-down state).Push power button for 5-10 seconds (this attempts to restart tablet after shutdown).
2. Hold power button for 30 seconds (this attempts forced shutdown). Push power button + volume up button for 15 seconds (this is called the 2-button  forced shutdown). Let it sit for 15 seconds (this allows it to run any shutdown routine and achieve a full powered-down state) . Push power button for 5-10 seconds (this attempts to restart tablet after shutdown).
3. If you had previously configured a USB mouse or keyboard to awaken the tablet from sleep, attach the device and push any button or key. People who have the original docking keyboard are able to wake up their tablet by redocking it because when first connected, the keyboard  was automatically configured to be able to wake up the tablet from sleep. The tablet will not respond to a bluetooth mouse or keyboard, because the tablet disables bluetooth mice and keyboards in sleep state to conserve battery ,and this cannot be changed in device manager settings.
4. Attach a USB keyboard. Press Ctrl+Alt+Del (self-explanatory). then push up arrow key once (this takes you to the shutdown icon, but you can’t see because of the black screen.). Push Enter. Wait 15 seconds (this allows it to run any shutdown routine and achieve a full powered-down state). Push power button 5-10 seconds (this attempts to restart tablet after shutdown).
5. Sometimes anything attached to the tablet can prevent it from waking up. Disconnect all attached devices including power cord. Hold power button 2 minutes( to force shutdown). Wait 30 seconds, then press power button again 5-10 seconds (to restart).
6. Draining the battery fully will shut down the tablet but can cause problems, so do this only as a last resort and at your own risk. If battery is fully drained, it may actually take a few DAYS on charger to be able to recharge it again.

Once you have recovered your tablet, you can try to prevent this from happening by:

1. Change settings to disable sleep mode completely. However, keep in mind that this will drain your battery faster and you would need to manually shutdown the tablet after each use.
2. Update BIOS (be careful not to brick the tablet).
3. Update graphics driver if possible. The Update Utility won’t work. There is not a downloadable updated driver for Z8300 processors for Windows 10. My tablet was pushed a driver update on 3/02/16. See if your tablet’s driver was updated as well.
4. Exit out of all programs before entering sleep mode.
5. Configure a USB mouse or keyboard to be able to awaken the tablet from sleep.

Tablet boots up to black screen

You may see a  the Chuwi logo for a few seconds followed by a black screen. You may or may not see a mouse on the screen This has been an issue on other tablets besides Chuwi tablets on Windows 10. What is happening is that the lockscreen is appearing as a black screen.

Press Ctrl (this takes you to the PIN/Password input screen, but you can’t see it). Enter your PIN/password, then press enter.

If you still have a black screen after that, then force shutdown with power button held for 30 seconds or power+volume up for 15 seconds. wait 15 seconds, then power button for 5-10 seconds to restart .

To prevent this from happening again you can try updating BIOS/drivers, disable fast startup or other methods described in this forum:

My tablet was automatically pushed a graphics driver update on 3/02/16

Hello. Thank you for your detailed instructions. I have Chuwi hi10 Q64G42151202677 model. with c106_B101UAN.607 x 64 version of BIOS. I have a problem with plugging/unplugging hdmi cable to TV. When I plug it, I see windows on TV, black screen on tablet. When I unplug the cable, the screen on tablet starts flickering. My Intel HD drivers version – 20.19.15.4308 from 22/10/2015

Could you help me with this issue? Maybe you can give the link to the latest Intel HD Graphics driver?

Thank you.

I won’t be able to get to my Hi10 until much later. For now, try this:

With tablet attached to TV so that you can see the display, try attaching USB keyboard to tablet. Then push window button+P. This should bring up display menu. Not sure exact word used, but select “duplicate” or ” project”  ( the selection above “extend”). You should now see screen on both tablet and TV.

Will update with more information after I have tried it myself.

Thank you for your reply. The problem was in case with magnet. I don’t know why, but it influenced on the tablet when rotating.

But now I have another problem. Display is flickering. I tried to reboot, it didn’t help. I read that bios update fixes it. But I have ***2677 number of tablet. 607 version of BIos as I know is the latest for this tablet. Right?

The second problem is charging with full brightness. TechTablet’s review says that need to change it to Surface 3  charger. What do you suggest? Maybe use another charger?

 

Thank you

[kravmama1]

Glad that you figured it out.

I know nothing about BIOS, so suggest that you post your question on one of the BIOS threads.

I have read that the original charger has difficulty charging the tablet when tablet is being used. Try a different 5v charger capable of at least 2 amps. Else, you may need to turn your brightness down to charge while in use. I am able to charge while using the tablet with an old 2amp charger that I had for the original Kindle fire tablet, but my brightness setting is at 25%.
