I got a Dell Inspiron 640M for free. I needed to get an inverter that received already and a backlight for screen that I just ordered. Originnaly it had thermal tape. I ordered replacement of 0.5mm thickness. Is it sufficient for the cpu and video card? it has 1.66 gig 667fsb dualcore with 2 gigs ddr2-667 memory. I will open my external hdd to get the hdd and dump it inside so ill be done with laptop. Anything you could add or suggest me ?
