Re: Thinkpad Yoga 14 20dn black screen, no bios logo



Hello piernov, thank you for your help. Unfortunately I can't find a supplier that can provide me with this chip. Maybe somebody know a supplier preferably located in Europe.

This are the details:

Device: Lenovo / Thinkpad Yoga 14 / 20dn
Mainboard: LCB-1 MB 13323-2
BIOS-Chip: MXIC / L150515-10G

Thank you very much folks!...

Hello guys,

I've got recently my hands on a Thinkpad Yoga 14 (20dn) which will not boot up. (black screen, no bios logo)
When I press the power button, the keyboard illuminates and the FN-Led lights up. Also the fan spins up. But thats it, nothing else.

For my understanding it could be a bricked BIOS. Unfortunately I have no exact history about what happened with the laptop.
I disassembled the hole thing to locate the BIOS chip but didn't find it.
The mainboard is a LCB-1 MB 13323-2.
I did a little bit research on the board and found ebay...

Hello everyone,

I'm a sysadmin from Cologne, Germany who likes to repair things.
I found the forum through a Google search because I've just got my hands on a Laptop which has a bricked BIOS I think.
Apart from that I'm looking forward to participate in this community!
