Lenovo flex 5-14alc05

[simonemont]

Hi,

I'm trying to fix my daughter's Lenovo IdeaPad Flex 5 14ALC05, the screen simply stays black and the Esc and Capslock LEDs are lighting up, fan is on.

S/N: PW023V0L
MTM: 82HU00MTIX
MO:: PWN0B2511006

I dumped the bios with my CH341A but it seems that the bios is "empty". I don't know how to recover the DMI

Can anyone help me?

Thanks

Make more backups and compare them. Are you using a clip, is the chip supported

Thank you so much!

i am dealing with 74M12JWSIQ which doesnt get detected.

IC not responding
Current programmer: CH341 Black

LC56-14A SVT
203021-1

Suspecting faulty ROM. Any recommendations as replacement?
Would Any 1.8V 120 Flash size would work?
XM25QH128A I have here seems to be 3.3V

It doesn`t get detected because you are doing something wrong or the chip is not in the support list. Don`t assume it`s a fault ROM just because you can`t read it. Choose a different chip that is in the list for example W25Q128JW (1.8V) and try reading it again. If you`re using a clip or pogo adapter it`s not the most reliable way, desoldering the chip and putting it in or on an adapter is the best way.

Thanks SMDflea
I should have specified that this is with the ic desoldered and placed on a SOP socket on 25xx side
I have tried with the clip initially, but hasn't detected it. Unless that clip damaged the chip somehow. :/

Where the XM25QH128A IC on that socket reads fine, but gives me this error when programming XM25QH128A with GJCN27WW.bin or W25Q128FW_dump.bin from another but same board numbers.

Seems there is no W25Q128JW on the CH341 Black list. Has anyone come across new list updates? My NeoProgrammer 2.2.0 Chiplist is from 29/09/2021

You can add new chip support to NeoProgrammer https://www.badcaps.net/forum/troubl...41a-programmer

Attached is ASProgrammer 2.1.2 ,it has pretty good XMC support.
Attached is my NeoProgrammer chiplist ,the 25Q128JW is supported.
