Acer Aspire 1640 Laptop Upgrade



Just updated an Acer Aspire 1644 laptop from Windows XP. The installation
went smoothly, nothing was lost or messed up. But I noticed that the fan on
the CPU was running constantly. As I had read a number of posts before the
install I recognized that the CPU was running at 100% (verified in Task

So, based on th posts I stopped indexing. It made no difference and I
suspect it makes no difference on any computer. And Vista ran slower than a

same problem on my Acer ASPIRE 1620... what did I do? I just opened the

It is quite an easy operation, you don't need to take off your processor,
just open the box which contains the fan and clean it, about 30 minutes of
work considering everything.

After this the fan was not working so hard, even with the cpu running at
