Compaq Presario CQ56-102SA

AMD v140 2.3GHz Single Core CPU (s1g4 socket)

6GB DDR3 RAM (Upgraded from stock 2GB)


Windows 7 64bit


I hope thats enough info. Please ask if more is needed and I'll try get it


A few months ago I decided that I wanted to upgrade my laptop as it isnt really fast enough for what I do. (video editing and rendering)  

I first bought 6GB of RAM and installed that with no problems, the laptop improved but not by a great deal. Someone suggested I upgrade the CPU so I stupidly thought that any CPU with an S1G4 socket would be compatible with my motherboard. I bought a Tri Core AMD Processor (cant remember which one) and iinstalled it myself using internet tutorial videos as my only guide. I tried to boot up the laptop after I had replaced the CPU and re assembled it but I just got a black screen so I did some searching on my other computer and found that the CPU I bought was not supported by my motherboard (or BIOS?!?). Anyway I put the old original CPU back in and the computer booted fine, but there was a problem. The computer would no longer charge so I bought a new DC port and fitted it but it still wouldnt charge. I was later told that I had fried the motherboard either by trying the new processor or doing something wrong when I fitted it.


I have not bought a new motherboard but I still have the same slow processor so I am still looking to upgrade. The new processor I want is listed in my laptop manual as compatible so does that mean I will be able to buy it and fit it myself and the computer will work with no problems? Or should I buy it and get a professional to fit it?


Thanks for any help received, Adi.

its likely you fried the motherboard with the new CPU-it probably drew to much power and over volted something, thats why its important to check the compatibility list first. As far as installing a new one, if you know what your doing, are extremely careful and have good thermal paste, you can do it yourself. If your not comfortable doing it, a professional is more expensive but a safer bet.

Hi. Your reply pretty much confirmed what I was already thinking about why the motherboard stopped charging. The best processor listed in my computers manual is a 35W dual core so would any 35W processor with the same socket work with my machine?


Thanks a lot for the useful info.
