I opened my laptop (Accer) to clean it up like I've done many times before, but this time round when I closed it up it wasn't powering up. Not coming on and fan not moving, (but power light showing charger connected was coming on when I connected it's charger)

So I opened it up to check the connections by disconnecting and reconnecting everything.

I noticed a chip on the motherboard (ITE-IT8987E-1527-BXS-AC30AA)

Which is the I/O chip would become very very hot whenever I connected the battery to the motherboard.

The battery was fairly fine before I opened up the laptop, (it's a 2 hours battery, and had probably lost some power strength in the last month) . I opened it up because my keyboard was acting up, and hence in cleaning up the keyboard I cleaned everything else.

Nothing smells burnt on the motherboard.

Could the battery have decided to die as I opened it up??? Or is something on my motherboard damaged??

I'll be grateful for any help

Some better focused pictures would help.
The whole PCB if possible.
Then hopefully you will get some answers.
What did you clean it with?
Good luck..............
