I've owned a Vaio VPCEB46FX i5 processor for 18 months. Worked well for the first year but for last 6 months, the fan comes on at high RPM within 1-2 minutes of turning on the laptop, and within 5 minutes the unit feels hot. the battery life which used to be about 3hrs, has declined to 1 ever since this began happening. I opened the bottom and blew out any dust in the fan assembly (there was not much) but this did not help at all. Can anyone tell me what my next steps for diagnosing the problem and fixing it should be? Thanks!
