I see that it's been acouple of years since you asked this question, but though I would throw somethings at you to try. First I never had any issues with my netbook, which is the same as your got and about around the same time as yours. Now after acouple of years I have notice browsing to be an issue and the LED which is no stop running my mine tells me that something is using up way to much resource, or the hardware is wearing out, that could be anything from the battery to the hard-drive. I would suggest placing both and since hard drives are now go Solid State Drive (SSD) you might want to go that route. Also update your OS to Windows 10 for free if you still have the Windows 7 Starter software installed. Plus once in awhile system clean you system. My choice is CCleaner, also have a good Anti-Malware soft install and uses the free built in anti-virus program in Microsoft called "Defender".
