|My laptop is an HP Compaq Presario with AMD Turion 64 2.0 GHz, 1 GB RAM, 80GB HDD using Windows XP SP3. I was able to restart/standby/hibernate the laptop without any problem until recently. But now, though it can enter restart/standby/hibernate status smoothly, it would not wake up or resume most of the times. Only the lights for power, volume etc. would come up but the screen remains blank and there would be no light from the USB mouse. The hard disk indicator would not blink and the system sound will gradually become louder (may be it is heated up).|
However, when I press the power button for a while, the system shuts down and it would resume/wakeup from whatever state it was before – from hibernation or standby or restart.
Please help me to resolve the problem.
