Question about Toshiba Satellite L455D-S5976 Notebook

1 Answer

I'm trying to figure out a toshiba satellite l455d-s5976 laptop. It shuts off automatically. If you leave it off for days, then it will run longer (30-60minutes) before it shuts off. Once it's off, you can turn it back on but it will only run a couple of minutes. Sometimes, it doesn't turn back on at all! I called Toshiba which made this piece of ****, and they asked for more money. The computer is barely used. My mom used it for skype and email basically. I know it's a lemon, but I'm hoping it's not a complete loss. If it is, it's time to buy another NOT-toshiba laptop.

Hi,

It's difficult to determine the exact cause of the problem but from your description it would appear that the laptop CPU is overheating. This would cause it to shut down as a safety mechanism to prevent your CPU or other components from permanent damage.

The first thing you need to do is open the laptop or have it opened by somebody in the know.
There are inlet & outlet vents whereby air is sucked in over the CPU which helps to keep it cool. These vents have filters which become blocked by dust & other debris in the air.

Cleaning the dust from these filters often sorts out overheating problems.
If this is not helpful in your case, it would be advisable to have a technician do further tests to determine the problem

Best wishes,
Graeme
