A30 motherboard question

[david_parry]

I have a thinkpad A30 whose battery charging circuit has failed. I also have a spare motherboard which appears functional with the exception that it will not boot due to a unknown BIOS password being set. From reading various posts on this subject I understand that BIOS passwords are difficult to retrieve without some technical expertise. My question is, could the EEPROM integrated circuit (from my own laptop - which has no passwords set) be transplanted onto the BIOS locked motherboard (in order to achieve a fully functioning thinkpad with no BIOS lock problems). If anybody has previous experience of this or knows of any problems which may arise, it would be helpful to know before I visit my local electronics repair man to see what he has to say.

thanks (hopefully)

Welcome to the forum!

What you've described is not doable.

The charging circuit issue is likely a blown fuse, which may or may not be easy to locate and replace.

At today's A3x series prices though, a replacement motherboard shouldn't be expensive at all...

Good luck and keep us posted.

Speaking of fuses on the A30 MB... I've seen one for another MB on here, but does anyone have a graphic of all of the A30 fuse locations? Hand drawn or graphic. I have the same "not charging" problem on another A30 system I have.

Not as nice as the one Nick made for the T4x, here is a hand drawn one for A3x.
