I know this may have been posted on here before, and if it has I am sorry!
Anyway, have discovered this evening that my laptop has started suddenly shutting down. The first time it happened I was browsing the web and it had been on for 40-45 mins when it suddenly turned off within a seconds with a high pitched squeal/ pew sound. I then turned it back on, and the same thing happened almost immediately. After leaving it a few minutes I tried again, only to find that once I had logged in the same thing happened.
The laptop is about 6 years old. It was made by Toshiba and has the 1st gen Intel core i3 processor. About a year and a bit ago it had a replacement battery fitted, and it recently had the free Windows 10 upgrade.
Would I be correct in saying that it is overheating?? Someone said to me the other week that it felt hot around the fan vent, though it has always been relatively warm around that area so I didn't take much notice. The fan has been noticeable from new and I don't remember really noticing it that much tonight, so could that be the culprit?
Any replies would be greatly appreciated.
