Toshiba laptop turned off and will not turn back on

[Lazy420]

I have a Toshiba laptop that shut off by itself and won't turn back on. The LED lights will not even come on. I have only had it for 2 years but I use it a lot. The warranty is no good anymore so that is not an option. When I plug the power cord into the wall it still doesn't work so I know its not the battery and I the power cord I have works with an older Toshiba laptop (broken beyond repair) so I know its not that. I have tried the method where you take out the battery and hold the power button down but it still doesn't work.

Anybody have any suggestions?

It sounds like your dc jack might need replacing if there is no LEDs when you plug it into the wall can you try this on your laptop the next time you plug into the wall riddle the cord near where it plugs into the laptop and tell me if the LEDs come on.

There is a known weakness with these things caused by the graphics chip overheating and lifting off the main board. There are two cures - one is a replacement main board which might be difficult to obtain and also a re-flow of the chip's soldered connections. This last needs specialist kit and will not be a cheap fix.
The final option is the great re-cycler in the sky!

There is a permanent fix for the graphics chip it involves Reballing which will cost a bit but it is permanent.

No I tried and its not the DC Jack.

same as a re-flow which is what we call it this side of the pond!

Reflow involves reheating the chip where Reballing involves putting new balls on the graphics chip.

This is Reballing
