z61t Freezing Problem

[UNCrules2187]

Hey all,

This problem just started happening last night, but now without fail it's happened everytime since yesterday. If I have my z61t on A/C Power, it seems to lock up after about 10-12 minutes of operation. I've found that on battery power, it doesn't lock up. However, my battery has degraded to the point where it only holds a 45-minute full charge, so this isn't optimal. Anyone know why it seems to freeze when it's on A/C power?

This problem happened to me once before (one day early January), but after about 5-7 times it worked itself out and stopped freezing so I didn't think anything of it. However, it has happened probably 8-10 times now and it's still happening even after I've turned my laptop off for a good 8 hours.

Thanks for any help.
