A recent BIOS update from Lenovo has bricked the laptop.

Hello

This device came in with a strange problem,
The laptop starts by resetting the time and date settings every time it is turned on, as if the RTC battery was removed.
RTC battery is brand new, 3V is present at Q2502
No liquid damage or corrosion, board is clean
Same on AC or battery

schematic and boardview can be found here

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...

This is the bios that messed all up...

The USB drive is poorly made, that's why the utility says it's protected by EEPROM.
Otherwise, try another drive or a smaller one.

Read my various posts on these pages.

Use the formatting tools and then enter the contents of the USB drive.​

L13 gen2 can't be unlocked by patching bios, you have to read EC, I think is an NPCE. Or try [B][URL="https://www.badcaps.net/member/240937-maxpower3"]Maxpower3[/URL][/B]​'s method:

Could somebody, please help me? I was able to extract 32mbs from the web update, but I couldn't find the BIOS 2 16 mb part. If somebody has it, could you send it for me? That would be very helpful now.

Hello everyone,

I have a Lenovo laptop (ThinkPad L13 Yoga Gen 2) that was interrupted during the bios update and no longer boots.
After my initial research, I came across this guide: [url]https://www.partsnotincluded.com/flashing-the-bios-to-fix-a-bricked-lenovo-laptop/[/url] . However, it fails at the first step to get a clean bios, because the .exe file does not extract a .WPH file under the following file path %USERPROFILE%\AppData\Local\Temp\WinFlash nor does it help to extract the .exe.
After further research I came across the following post in this forum: [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/94408-bios-for-thinkpad-l13-yoga-gen-2[/url]...
