No.. Never try to overclock CPU of a laptop, the clock gains will be very much less, the headache that you might get by doing this could be much bigger...
Due to it is 1ghz it's cpu heats a lot but i am trying to avoid it but it moer irritates when i am in a seminar and between the seminar it heats up with no reason i just formated and installed win 7 pro but the same problem just 1 ghz as one of my client is have a upperversion of it x53u and it is running ok.
