Try the full minute but such a disconnect can cause parts to fry. At worst this is a new motherboard. Thankfully I find the files to survive even this!
Last night i was running a virus scanner and accidently disconnected the battery in the middle of a scan. Now pushing the power button has no effect no fans no lights (except the light that shows its plugged in) nothing. Ive tried un hooking the battery and the power cord holding the power button for thirty seconds and hooking everything back up but to no avail. Any suggestions as to what might be the problem
