My laptop is a HP Pavilion DV6000. I bought it in Sept 2011, so it's pretty old. The original battery that came with the laptop went kaput in early 2014, so I got myself a new (authorized) battery from HP locally. It's been fine since. But for the last couple of days, my laptop's been heating up a lot. The Fans been making a lot of sound too. I figured I'm using a lot of RAM and that the graphics card must've been running too (Since I've been playing some games on my laptop last week). I stopped playing games since yesterday and have been using applications carefully (without using several applications simultaneously). But since yesterday my laptop shut down abruptly twice. When I switch it back on after plugging it in, it showed 60%and 75% respectively. Since today morning my laptop is charging to 75% quickly, but then lagging. It's getting to 76% after like 15 minutes and then slowly climbing. So does anyone have any idea of what the problem may be? I know my laptop is old, but it functions well. I haven't had any problem with it a lot. Do I need to get my battery replaced? Or do you think the laptop is overheating because of dust? I can go to my local service provider and ask him to take the laptop apart to dust it. What should I do? Any advice, suggestions?
