Question about HP Compaq Presario 2100US Notebook

1 Answer

On my Compaq Presario 2100US my screen has started going black intermittently while running. I then have to power it down using the power button because I can't see the screen to shut it down properly. What could be causing this? Thanks.

  1. Remove the battery & switch on the PC in AC mode.
  2. Check if battery charging indication or AC power on indication is glowing. if not then need to change ur motherboard.
  3. If indication is OK, but could not power ON then check ur RAM for any loose connection or dust. clean & reinstall.
  4. If still no display, connect an external monitor, check if display is comming.
  5. If Display is coming then your LCD need to replace.

Won't start but CPU fan vibrates but will not go full blast. Intermittant


It appears you have a faulty CPU fan and it is causing the CPU to overheat and shut down.
I suggest you replace the CPU fan. remove any dust from the heatsink and put new heatsink compound on the CPU/heatsink.

Presario blank screen


I think this might be a common problem caused by windows sleep/hibernate not working (MS never actually got it to work well)
Try holding down the power button for 30 seconds. Wait 10 seconds, then start up again. If you get the same problem, try tapping the space bar repeatedly...
Otherwise your going to need to boot off a windows disk, and do a re-install/repair.

Compaq V5005us is weird. Powers on with black screen and freezes


It sounds like your Video card and/or motherboard are starting to give out or your LCD is giving way. Try plugging the laptop into an external screen and see if it still acts strangely or even displays on the external monitor.
