The dead battery can pull more power, create more heat, possibly burn out things or worse. I'd remove the dead battery as well as do the usual canned air and heatsink work (that work is on the web if you didn't know about it.)

Hello,
I am doing window 7 updates on a gateway computer. The computer was working fine until the updates occurred. it restarts, turns back on then it shuts down. when i turn back on, the computer goes to the desktop but it shuts down unexpectedly.
The computer battery went dead since it was about to die but this behavior started after.
What is going on?
