Dell Vostro 220, power up problem 2 months ago. Pressing power button, amber light flash once then nothing. Repeat, nothing. After about 100 tries, before I gave in, somehow the PC started.
Since I turned on the PC 2 months ago, I have kept it on. At night I put it into sleep mode (with blue light flashing, not hibernation). For the first 2 weeks, I can wake up the PC by clicking the mouse. Then clicking on the mouse didn't work any more, so I had to press and hold the power button for a few seconds to shut down the PC, then in a few seconds press the power button again to power on. However, if I only put the PC to sleep for a short time, say 30 minutes or so, then I can wake it up by a mouse click.
Weird thing is, shortly after I turn off the PC, when I press the power button, after about 2 seconds delay, amber light will flash once, then blue light came on then the PC starts.
When the PC is on, it works fine without any problem. So I used this trick to keep it alive.
Unfortunately, today my nephew came over and he shut down the PC when he left. By the time I found out, the PC was left in the "cold" for a few hours, and I haven't been able to turn it back on again. Same as in my last post, it will flash amber once when I press power button, then nothing.
Most strange isn't it? I am considering the following 3 problems:
1. CMOS battery failure: not sure if CMOS battery issue would prevent power on at all though?
2. PSU failure: not sure because the PC works fine when it's on.
3. Motherboard failure: could it be some capacitor issue? since If I keep the PC on, or just in sleep mode for a short time the PC seems to boot up or wake up no problem.
Please Help!
Thanks!
