|Windows 2000? |
Dell make/model laptop?
Age of laptop?
It's hard to say exactly what the issue is. If the AC adapter is proved good, you either have:
- A motherboard component level malfunction issue (bad motherboard).
- An AC adapter connector issue ON the motherboard where the AC adapter plugs into the motherboard providing it with power.
- Bad power switch on laptop.
- Bad fan (but that would usually give you a screen component failure error).
Just another stupid saying...
