Hello. I have an old Gateway M350WVN laptop which was running extremely slow and the battery wasn't lasting very long. Upon further inspection I noticed that it is idling at 50 degrees Celsius which explains why the fans are running so much which is killing the battery and I assume also slowing down the computer. So I opened it up, cleaned it out and reset the CPU with Arctic Silver 5 and no luck. I'm not real familiar with laptops. What should be my next step? Thanks in advance for any help!!!
