Hello everyone !

My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...

Hi there, I'm hoping for some help. I did a bios update a while back, and have had problems since - laptop taking 30-60 seconds to post during boot, unable to correctly go in and out of sleep mode, causing battery issues. I tried to redo the BIOS update but it fails each time. I googled around, and there's lots of similar symptoms on the same model as mine, where people say the ME Region is corrupted. When I boot to my BIOS, alongside ME is blank. I've tried to follow a few guides but am struggling and hoping someone can help me.

I have a CH341A

Hi,

I have 2 x Lenovo Thinkbook G2 ITL laptops. They seems to be identical specs, both 11th gen, 1135G7 cpu, both 12gb ram and both 256gb M.2 ssd.
I have ensured both have the same latest bios and ec firmware.

One of them works totally fine however the other has charging issues.

I have compared both motherboards in diode mode and cannot find much of a difference anywhere.
I have swapped the motherboards over to the other casings and the issue transfers.

It's behaviour is it will connect at 20v on USB-C and always start to charge....

Hi all,

Would like to ask some help to bring my L13 Gen 3 AMD laptop back to life after a BIOS update gone wrong. I was updating to BIOS 1.30, as always, laptop connected to AC, didn't touch anything. 1h later the screen was black and the laptop didn't respond. Waited 3 more hours until I decided to just turn it off and on again. Now it doesn't show anything on boot, keyboard light turns on a few seconds and then nothing, just the light on the power button. Left it all night, clicked the reset button, disconnected battery and cell coin battery for 2h... still nothing. Also tried...

Try the HARD RESET idea. This apparently will reset the hard drive so be aware of this.



To perform a hard reset (factory reset) on a Lenovo Flex 5 laptop, locate the Novo button (a small pinhole reset button), press it with a paperclip while the laptop is powered off, and follow the on-screen instructions to choose "Remove everything" to erase all data and restore the system to factory settings.
Here's...

My lenovo v330-14IKB gets to hang up on the Lenovo Logo screen for a long time (about 30 seconds or so) due to a Mouse radio transmitter (A4-tech wireless mouse) attached to a USB port. If no transmitter attached the Logo-stage will get to be passed fast enough. I guess the same may happen due to any non-bootable or non-storage device attached during the boot-time....

I think I found the problem... some voltages are missing from the board.
VCCIN and P_VCCIN_PH1_S 0V. I think I need to measure at least 0.7V on PL3400.
Can someone confirm this?...

Attached BIOS works. But laptop shutdown exactly after 30 minutes (even in BIOS Setup) after startup.

Please advise / help. Thanks....

[FONT=Calibri]Lenovo G50-80 (80E5) boots normally (e.g. Windows or Ubuntu).
Processor is Intel Celeron 3205U
Latest BIOS Version is installed: B0NA0WW, 30.09.2016

But the laptop shutdown exactly after 30 minutes (even in BIOS Setup) after startup. Obviously, this is controlled by the BIOS.

Could be a corrupt BIOS (MEI)?.
Does somebody know how to fix that?
Is it required to read, patch and write the BIOS chip UC3 from mainboard? Any suggestions?[/FONT]
