Damn! My laptop was making strange noises recently, and now it tells me the cooling fan isn't working properly and I shouldn't be using it at all. (Don't worry, I'll shut down in a minute, before it gets a chance to get hot!) So - any ideas? Do I need an engineer to solve it, or is it relatively easy to repair?

GO INA! GO INA! GO INA! GO INA!

just showing your laptop how a fan is supposed to work

Take the back off (carefully) and check the fan and cooling fins Ina, they get clogged with dust and cease to cool the processor.
I have to do mine with rather embarrassing frequency, maybe because our duster went missing some years ago.

Maybe your duster eloped with mine Tony

Yeah, mine's getting noisy again, too. I think I may need to take it to bits and pick the cat hair out of the fan, again. I can't remember exactly how I did it last time, but apart from being careful in case of accidentally pulling on delicate wires, I don't remember it being too difficult.

Thank you for your encouragement and advice... The screwdriver it is, then.

Yeah, dust is a major problem in this house - no idea where it comes from, really, although I'm sure the cat contributes to it...

it doesn't look easy to take a laptop apart...

Go to youtube & in the search box put… how to remove cover on xxxx laptop …. And someone will have posted a video showing how. Take notes on the screws to remove & just as importantly those not too if you can’t use another computer whilst doing the job…. This also works for almost ‘anything’ you can think of.

I didn't actually have to take it all apart in the end - just took a cover off, and now I try and keep the dust away from it where possible...
