About a month ago I started having problmes with my computer.
It would not "wake up" when you moved the mouse after leaving it ON, but idle for a while.
I would do a forced shutdown with the computer power button and then it would work again. That only worked for a few days, then even a forced shutdown would not work when restarted.
I took it to the local "GEEK" repair place. They called and said they could not duplicated the problem. They said sometimes you have to unplug the computer and let the "electric drain off" and that must have been why it worked OK for them when I brought it in.
I took it home and it worked only the first day. I even went to the "sleep" settings for the computer and set them for NEVER.
I took it back and told I still have the same problem. They had it a week and said they could not duplicate the problem and it might be the monitor, please bring in the monitor.
I took the monitor in. A week later thye called and said the monitor was the problem. It was not "waking up" from it's power saver/sleep mode.
I had old tiny monitor and so far so good!!!
I got spoiled by the bigger monitor I had, so time to once again go monitor shopping. I have room for a 23 or 24 inch monitor.
