hello, this Dell turns on but the screen remains black, if I press the power button a second time the fan turns at max and turns off, the voltages I measured in the pads are all, I tried to warm the cpu / gpu chip but nothing has changed, could it be a bios problem?

Re: Dell e5440 turns on but the screen remains black
Make sure RAM is good and compatible, and that you tried disconnecting any devices.
If CPU VCore is present, try to flash the BIOS.
Don't mess with the GPU or the CPU themselves randomly.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView -

Re: Dell e5440 turns on but the screen remains black
I flashed U2, the programmer ch341a told me file length, beyond range of will be ignored, I turned it back on, now the LED flashes 5sec on and 5 sec off and does not start, maybe the file is not right or I have to flash U1 too ?Comment

Re: Dell e5440 turns on but the screen remains black
Are you using those clip things to connect the ch341a to the bios chip while on motherboard? I have found that it doesn't always work 100%. I take off the chip and solder directly to ch341a pads, and yes, flashing U1 might work. But save your original .bin first of course. I have a e5440 board with dedicated graphics if you need those two .bins. I'm not sure what's wrong with it though. I know it's not the bios.Comment

Re: Dell e5440 turns on but the screen remains black
I gladly inform you that after flashing U1 the screen turns on,although ch341a says file length etc etc, it probably doesn't affect
, thanks to everyone for the valuable advice,

Re: Dell e5440 turns on but the screen remains black
everything works fine only when I turn it on the screen comes after 20 sec. I also downloaded a last 8 mega bios, downloaded from the dell site, but the problem remains, it can remain even so but if I can improve it is betterComment

Re: Dell e5440 turns on but the screen remains black
You have a dual bios,you should flash U1 and U2 .If you can`t clean the ME yourself make a new post in the bios requests sub forum ,post both your original bios backups https://www.badcaps.net/forum/forumdisplay.php?f=40

Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
