Question about Dell Computers & Internet
When you turn the Dell Inspiron 7800 on it keeps powering on & off.Till you un plug the a/c adpater.And it trys to Boot.
Keep in mind since you cleaned it out, only have the AC adaptor hooked up to rule the battery out. If the laptop stays on with only the ac adaptor hooked up and doesn't shut off then you know that the battery is faulty. If it still shuts off even with just the ac adaptor hooked up then it could be the ac adaptor.
Also check one more thing, with only the ac adaptor hooked up, wiggle the cord where it plugs into the laptop and see if the laptop shuts off, if it does then the dc jack on the motherboard is loose and needs to be resoldered back into place so it stays put.

Remove the battery from its compartment on the side of your Dell Inspiron laptop computer.
Remove the power adapter from its plug on the side of the Dell Inspiron (if your laptop is currently plugged into a wall outlet).
Press down and hold the "Power" button on the laptop for one to two minutes. This will dispel the excess electrical current that is built up inside the laptop.
Put the battery back inside the compartment of your Dell Inspiron.
Plug your power adapter back into the side of the Dell Inspiron. Press "Power." Your laptop computer will now turn on.
hope this helps
