My laptop spec:

Model : Acer Travelmate 4052LCi
Spec : Intel Pentium M 725 processor (1.6GHz, 400MHZ FSB, 2mb L@ cache)
15.0" XGA TFT LCD
80gb hdd
Dvd/Cd-rw combo
256+512mb ddr
802.11b/g wireless Lan

Don't know what is the prob. When on laptop using plug, it suddenly hang. Need to open laptop using battery after 1 or 2 hours then only can use plug then it will not hang. The screen also like to automatically turn off when it is overheat and memory too high.

How much you can take?
