hey guys, me and the techs here are having a bit of an issue. We have a customers notebook. Old hardware but runs decent. It does not show the post screen when you turn it on. The cpu is fine, we tried multiple cpus so we know that isn't the issue. We checked the hdd the heat sink the cdrom, battery or d/c jack no issues with that.
every so often it will show the post but we were thinking its the ram. so we try different sticks of ram, somehow with new sticks the notebook boots up no problems, but to see if the old ram is shot we place the old back in and the computer boots up. when you turn the note book off and on a few times it will boot into the post screen then to windows or it wont show the post screen at all and just hang with a black screen. since the problem has been replicated multiple times we still cant find the underlying issue, I was wondering if any of you have a solution or have had this problem
and also when an external monitor is plugged in, its the same issue if the monitor wasn't there, either it boots or it doesn't and will or will not show the post screen
specs of the book is here:
