first of all id like to say hi to you all, my laptop keeps turning itself off, it started doing it when i tried to watch clips on the internet or upload photos but now it does it more and more often, the fan gets louder before the laptop turns itself off (i dont know if this has anything to do with it) any help will be really appreciated

This pattern strongly suggests a thermal shutdown caused by restricted cooling. ’s test with an external fan and ’s point about dust in the cooling path line up with a common failure mode on older laptops: the cooling system (fan, fins, thermal interface) gets clogged or degrades and the machine powers off to protect the CPU.

Quick verification and safety

  • Check temperatures with a monitoring tool (HWMonitor/Core Temp/SpeedFan) while reproducing the load that causes the shutdown. If core temps spike sharply just before power-off, that confirms overheating.
  • Back up personal data before any stress testing or disassembly.
  • If the laptop is under warranty, stop and use official service.

Practical steps to try (low risk first)

  • Run the laptop on a hard, flat surface and test again. A cooling pad or desk fan can be a temporary fix.
  • Inspect exhaust vents for visible dust and lint. Clean exterior vents with short bursts of compressed air.

If comfortable opening the case (and not under warranty)

  • Power down, remove battery and AC, ground yourself.
  • Remove the access panel and visually inspect the fan and heatsink fins.
  • Use compressed air in short bursts while holding the fan rotor still so it does not overspeed. Remove dust clumps from fins and intake paths.
  • If temperatures remain high after cleaning, remove the heatsink, clean old thermal compound with 90%+ isopropyl alcohol, and reapply a thin, even layer of new thermal paste before reassembly.

When to replace or seek a shop

  • Replace the fan if it makes grinding noises, does not spin freely, or shows low RPMs after cleaning.
  • Take it to a repair shop if unsure about disassembly, if the motherboard looks corroded or damaged, or if the problem persists after cleaning and paste replacement. Labor can cost more than the part, so compare quotes.

Cautions

  • Do not use a vacuum directly on laptop internals (static risk).
  • Avoid canned air upside-down (liquid discharge).
  • Hold the fan to prevent overspinning with compressed air.

These steps should help diagnose whether a simple cleaning or a fan/thermal work is required.

Overheating? Fan not working? Laid on a carpet?

i lay it half on my knee when im using it so the fans are uncovered, i think the fans are working because you can feel the draft off them.

The fan sound makes overheating a reasonable diagnosis.

If you blow cold air into the laptop does it take longer to turn off? there are air intakes that you can aim a fan at.

Does it turn of if just idle and what is the laptiop so we can assess whether the CPU goes into low voltage mode when idle or if it has any low voltage mechanism when overheating.

hi there ive just tried blowing a fan into the air intake while playing a film on the internet and managed to watch 3:10sec! and it didnt turn itself off! so if i take it to a repair shop to get a new fan fitted that should do it. the laptop turns off completly and its a tosh satellite a30

If you can feel the hot air being blown out, it might not be the fan although greater efficiency won't hurt.

A good first bet is for the repairer to look at the mobo for dust layers or other air obstructions.

Anyway, good luck with that.
