My Dell Inspiron 1545 Laptop just stopped working. When I press the power button, the light turns on and I hear the fans run for two seconds, and then everything just shuts off. When I plug in the laptop, the charging light doesn't go on. Brought to geek squad, they tested charger and said charger was not working. They then tried a new charger with the laptop, and the laptop still didn't work. Same thing happens every time....light and fans turn on for two seconds, and then just turns off. they said it was probably the power source and to just buy a new computer. Help me please, I need my laptop.
Remove the battery, and try again. If it powers up, the battery is faulty. If not, remove the battery, unplug and hold the power button for 30 seconds. Try again.
If you still get nothing, reseat (remove and reinstall) both memory modules. If it won't power up thereafter, the mainboard is faulty. If you're out of warranty, this is a $300-400 repair - a new system may be a better idea.
In my case the issue was that the laptop would power off before getting to the operating system.
Through troubleshooting I found that I have a defective keyboard. I have removed the old one and am using an external until my replacement comes in. I hope this helps someone. . .
