This computer belongs to a Bridge Club for whom I am the scorer, web-master and sys-admin (You could do that Chris, you're good with computers !). It was built with Vista Home basic but I reverted it to XP SP3 because it didn't have the grunt to run Vista.
I took it down to the Club last night, switched it on and turned to hook up the rest of the equipment then realised it hadn't started up. I couldn't get it to start. I grabbed another computer from my house and carried on.
Looking at it this morning it seems there is a power supply problem. With the mains connected the charging light is showing green but nothing happens when you press the power button except a very brief 'whirr' from the fan which stopped almost immediately. There was power reaching the optical drive because I was able to open that and and try an XP install disc and the self-booting Puppy disc I keep handy. Both times the disc span up and ran for a few seconds and then stopped. There is no BIOS screen of any sort.
Without the mains connected, there is just a brief display of the power on light which then goes out.
The charger unit is putting out 19.4V off load, the computer hasn't been dropped or otherwise abused, it worked perfectly a week ago - for three hours on the mains at our meeting and then for about 15 minutes on battery at home when I ran it to get the results files off it and it shut down normally. Then it was just left sitting in my 'office' until I packed it up last night.
The computer is just over 4 years old. Is it possible the battery has died and this is one of those machines that will not run with a dead battery ? Any other thoughts ?
