Advertising GPD Xd charging issue
« on: November 08, 2015, 11:03:49 am »
Gpd just confirm me the problem.

Charging device 'power on'---> OK
Charging device 'power off'--> OK

Never do: If you charging device 'power on', never 'power off' device when charging.... it should DESTROY the screen!!!

Gpd will change hardware in the next batch.
For actual devices, they are searching for a software solutions

When i got more info, i'll say something

Please share

thanks

If I understand you correctly, powering the console off/on while charging will break the screen? Damn.

I turned it off / on while charging once, no problem... I must have been lucky.

Never going to do it again tough! Luckily i had already made a habit of not doing that.

I just hope an app never makes it crash reboot by itself while i have it in the charger...

But what does "destroyed" mean exactly? And does this happen almost always if you reboot while in charger or is this just a small chance of it happening? Does it happen on all firmwares or just the newest one?

Also...

Just wondering...

How did people install new firmwares then???  Because it has to be turned off, and it charges over USB right ? So shouldn?t everyone bricked their screens when installing new firmwares if you can not turn it off while charging? :-/

When the device is in bootloader mode to be flashed is not charging, even though it's connected via usb.

About that failure, I have powered off my device lot of time during charging and never have an issue with it, so perhaps only happen to some models or some batch.

 I don't know if it is always/ all devices...but the best is to not test it ;-)

Screen is damaged or probl?m with touchscreen...

Don't have more info for now....

But i think it is necessary to do an advertising for users...

Thank you for this explanation! But I mean, I usually (and I think most people) connect it, turn it off, then start the batch tool. So it would still be fried.

I think you are right about it only happening sometimes, maybe like the battery indicator bug on the g5a.
Altough, from what the OP said, it?s unclear to me wether it fries itself if you just turn it off while charging, or if you turn it off and then on while charging. Which would be more logical - maybe at boottime, there is a split second where the charge to the screen is not correctly regulated, and it gets too much current and is BBQ?ed.

Agreed! But, one thing - is the damage done if you have it in charger and turn it off, or do you have to have it in charger, turn it off, and then turn it on again while still charging to do the damage?

No need to do that to connect it to batch Tool. The best way to connect it in bootloader mode is just with the device Powered off, pressing vol + button while you connect usb cable and it boot in bootloader mode directly.

The problem happening is that the device isn't rebooting correctly, the screen goes black but the backlight stays on, and the battery isn't charging. You can reboot it only by holding the power button.
But if you leave it like this, it will slowly but surely damage the screen, the backlight and the touch panel, making them not working properly anymore (screen color "burned", and touch screen becoming crazy when charging).
I can't really say if it's random or not, once my device was damaged I was careful not switching off while charging...

It's just when you turn it off. When the problem happens you have to hold the button more than 7 sec to be able to reboot it.

To be a bit more precise, when you switch it off while charging, if everything goes well it should reboot in the "charging" mode, with the little battery icon in the middle of the screen, and the led on.
But when the problem happens, it doesn't reboot, it doesn't charge, the led is off, it just stays with the black screen and the backlight on.
I don't know if it has anything to do with the firmware, but mine was the 3.3.6.

AHa, that problem. Yesh, I had that once before with my XD, but I immediately noticed something was off because i wanted to reboot it, and it did not respond to the normal 3 second press. Also I saw the blacklight was still on. So I pushed it 7 seconds (I knew this from my q9, where I also had it once like 4 months ago, and I believe my archos gamepad 2 did it too once), it went off for real, then I turned it back on again normally. No damage at all.

I can imagine tough that ignoring it and letting it lay there like that for a few hours might cause some damage.

But, to summarize:

You can turn of and on device while in charger. but, IF the blacklight stays on when you try to turn it off while charging , immediately push the power button for 7 seconds. You will see the blacklight go off so you know it?s long enough. Do not ignore it and let it charge like that for any period of time, it might damage the screen.

And I had the same issue once on my q9, so from experience I can say that most likely the issue happens with the Q9 as well. It happens very rarely, usually when in charger it will turn off correctly, but if it does not, immediately press that button for 7 seconds and there should be no problem.

Off course, I just let it charge in standby. Much saver.

Now to be sure, am I right in believing that an app crash or android crash while in standby and charging (so I am not ever there, maybe not even home) can never result in this happening? Android always does a full reboot when it crashes right?

Thank You! And at least we know this can never happen by itself.

Altough a still wonder, maybe you can ask gpd... Could a crash forcing android to reboot from standby whike its charging cause this, kr can this only happen if you shutdown while charging via the menu? The former would be much more dangerous...

Oh and BTW, it does have to be in the charger for this issue to occur and/or cause damage right? It can't just happen randomly when you turn it off and it is not in charger?

im assuming this was the issue i had. My device powered on normally 2 weeks later after a full recharge(just left it in the drawer.) Then I formatted and flashed newest update. no issues since.

Why not just install that firmware update if they release it in a few days?

Altough personally, I am just gonna ignore it, I don't want to lose all my apps/data or have to back them up (not enough space), and I always charge it in standby so for me it's not an issue...
