Having problems with your HP Compaq Presario CQ50-110US Laptop ?

Shut down during use

\015 I was on my laptop and it just shut down. i have only had this since christmas. i am guessing it overheated? please help this is frustrating!!!\015

Answers :

If the CPU heatsink\015\012is not clogged with dust and lint completely, you can use canned air\015\012and just blow it inside the laptop through the openings on the bottom\015\012and on the sides. It’s nice as a precaution measure, but it might not\015\012work if your laptop already has a problem and the heatsink is\015\012completely clogged.

\015\012
    \015\012
  1. Open the laptop\015\012case, so you can access the CPU fan and the heatsink. In some cases you\015\012can access the heatsink through the latch on the bottom of the laptop.\015\012Sometimes you have to open the laptop case all the way down.
  2. \015\012
  3. Carefully disconnect\015\012the fan cables on the system board and remove the fan. If the fan makes\015\012unusual sound when it spins (grinding sound), I would recommend to\015\012replace the fan.
  4. \015\012
  5. Clean the fan and the heatsink with compressed air.
  6. \015\012
  7. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

My HP Pavilion dv9700 was over heating and would shut off. Then it wasn't over heating and would shut off. Now it won't turn on at all. The power cord is working and the lights go on for a second while I am pushing the button to turn it on, but the computer won't turn on. HP told me the problem was the motherboard. Do you think that's really the problem or could it be something else?

My Gateway model w350a T-series laptop overheats whenever I use it too long. I can tell it is overheating because when i feel underneath of the left side it is extremely warm. I recently got a new hard drive after the fan in the old one failed, and I never had the overheat problem before then. Could there be a quick fix for this problem?

Hi, i have an Acer Aspire 5730ZG notebook not older than 1 year.
