I have an EiSystem 4405 laptop 2.4 Ghz Celeron processor with a 30 Gb hard drive, 256 MB DDR RAM.
One night i was on it then it just shut down
I thought it might have been a cooling issue
So I left it off overnight and tried turning it on the next day and it didnt come on
I opened it up and tried cleaning out the fans as I heard this might improve cooling but that didnt seem to do much
The battery by the way is dead in it so I have it out
I left it off for a few weeks and tried a new power cable and it turned on
I put the old one back in and that worked too
So i thought maybe it might be the connection that connects the power cable to the laptop

Remove the power adaptor (and battery if it was in)
Hold in the On button for 30secs (dispersing all internal power)
Put the power adaptor back in
Try turning it on

Otherwise Yes, hardware issue, with connector or adaptor

Nope still didnt turn on
Guess its off to a pro then

make sure the power supply is the right one. many people overlook the fact that with the wrong power supply your system will not run optimally.

yeah the power supply is the right one
its the one that came with the it
