About a week ago, my laptop started making crackling noises coming out of the speakers, the cursor would lose control and randomly click. As well as this, the power adaptor was making a clicking noise. I unplugged it for a while. I tried plugging it in a different plug socket, and had the same problem. Later, I plugged the power cable in, and then put the power adaptor in. There was a large bang and the plastic on the adaptor blew off. I ordered a replacement adaptor, believing that to be the problem, which arrived today. It didn't work at first, but then I replaced the fuse in the mains plug. For about 20 minutes or half an hour, it was working fine. Then suddenly the monitor started flashing on and off, the clicking noise in the adaptor came back, the laptop switched off and there was a strong gassy smell.
Considering the moment when the adaptor actually exploded was when it wasn't plugged into the laptop, I'm guessing this is a mains plug problem? What worries me is that my laptop smells very strongly of gas and stuff. I'm guessing that means I've had some bad damage to my laptop. I'm not really sure. Any help?
Thought this was worth a mention, but I don't think it's related. The laptop battery is [bleep]. It's been telling me I need to replace is for a while. But these problems happen with the battery out and even without the laptop plugged in.
