My Dell Latitude laptop will not power on. It was slow for a few days and I was able to get Windows to load once and found that the battery is at 96%, so that is not the problem. Now I cannot even get it to load windows. The green light flashes for a few seconds then goes out.The fan doesn’t come on and Windows never loads; it just goes off. I think I may have a virus, and want to reload Windows, but can’t even get it to power up or bring up the reboot menu. What can I do?
1. Try starting your laptop without the hard drive. The hard drive can be easily removed from the bottom. If the laptop tuns on and loads BIOS screen, most likely have a failed hard drive.
2. If removing the hard drive doesn’t help, remove all other parts you can access except memory modules. Remove the battery, DVD drive, wireless card. In short, minimize the system as much as you can. After that try turning it on from the AC adapter. If the laptop gets power from the adapter (light turns on) but will not power up, this could be motherboard or memory failure.
3. Try removing memory modules one by one. Try tuning it on with only one memory module installed. Try different slots. If the laptop fails with each module, most likely this is motherboard related failure.
You can backup personal files from the hard drive using an external USB enclosure.
