Your laptop uses a 5400-rpm HDD on System C:/drive../
Change that to a 7200-rpm HDD..
The Processor is a AMD 1.3 GHz../
...I need to check that../be right back../

It seems to be the System C:/drive..at 5400-rpm
You need to find a 7200-rpm HDD that is compatible..
I would suggest a Western Digital Green/HDD 7200-rpm@160-GB's../

You might need a Clean re-install of the OS..
So--if you do replace the slow HDD with a faster newer design..
Do--the Clean re-install..NOT--a Transfer/
