Lenovo ThinkPad Edge E531 BIOS

[TossDon]

Hi guys,

I have a Lenovo Edge E531, MB Part# 04Y1299, won't accept any AC adapter, won't charge the battery and just shuts down after flashing the message that the AC adapter is not genuine( which is), this started after upgrading the BIOS.
Any one has the BIOS files, EC and Main? or any ideas?

Hi
it can coincidence, do you have another AC adapter to test ?

The AC have a small eprom that says to laptop power and model so it can be damaged on the process or miss writed / bad match from bios

regards

Yes, I have 2 adapters, both were tested on other Lenovo's OK, one was actually being used to charge it until the BIOS update, I know the 1 wire protocol to check the ID but I think it is the BIOS is messed up. Thanks though.

Did you solved your problem now? Did you try to reinstall the bios drivers?
