I've had the Lenovo G555 for about 2 3/4 years at this point, and I've had another part fail -- the battery.
A laptop battery losing its ability to hold a charge after two years is by no means unusual.
Laptop batteries can be pricey. I've seen them go for -- and that's for a computer that's worth maybe .
When my LCD power inverter went when I had the Lenovo for about two years -- a bit early -- and I was able to replace what is usually a part by spending and change on eBay, I decided to look around before committing to a new battery.
I saw aftermarket batteries going for anywhere from to . That's quite a range. Some claimed to be better. Those offered a two-year warranty. Most of the time, it would take another to in shipping to complete the transaction.
I've had my Lenovo G555 laptop (AMD Athlon II at 2.1 GHz) for nearly two years, and recently I've been experiencing thermal shutdowns while running prolonged, CPU-intensive tasks in Debian Squeeze.
Perhaps ironically but probably totally explainable, watching Flash video is not one of these tasks. I can watch Flash-delivered content in Hulu all night, and the Lenovo is fine.
The laptop overheats and shuts down when doing two things:
Java-heavy tasks like listening to networked, software-defined-radio sites like http://w4ax.com
Rendering videos in OpenShot
Two things that are very CPU-intensive, indeed.
So what did I do about this?
