PC repair call out services in London and Surrey: SONY VAIO LAPTOP

Overheating problems arise in all laptops whether they be from Dell, Sony, HP, Toshiba, Esystems, etc. Most laptops out on the market are fitted with one fan and one Heatsink but a lot of the time these fans are not capable of keeping an entire laptop computer cool and result in laptops swtiching off after they've been turned on after only a few seconds. We went on a callout to findout what was wrong with the customer's laptop. The client told us that when the laptop was switched on, the Laptop would come on with the hard drive lights, DVD rom lights and other light indicatiors coming on indiating that power was going to the machine. We then first thought that the ribbon conncting cable had come loose from the back of the screen so we took the screen out of the laptop to verify this. The cable had not come loose so we put the screen back into the laptop and then thought the GPU may be playing up and overheating so we stripped the laptop down (we didn't take out the motherboard at this stage). We then switched the laptop on and then found that that a lot of heat was coming out of the laptop. We then switched the laptop off, uplugged the power cord and then continued to strip down the laptop. We preceeded to take off the bottom of the case which then revealed the motherboard. We then took out all the screws from the motherboard, tookout the heatsink, leaving only the fan connected to the lower base of the laptop. We carefully lifted out the motherboard from the bottom base of the case and then placed this on a non-metallic, non-conductive surfce. As we had previously done this overheating job before, we then attempted to remove the old thermal compound from the GPU and CPU using a thermal removal solution that's used to remove silver thermal compound. With the remnants of the old silver compound removed we then replaced the old thermal silver compound with new silver thermal compound and then heated the GPU for 30 seconds. After replacing the heatsink over GPU and CPU we then put back the mohterboard into the bottom base of the laptop but putting the screws back in and screwing the mothrboard back onto the case. We then switched the laptop on and everything seemed to work. The laptop was then switched off and put back together again. As soon as everyhing had been put back we switched the laptop on for one final time and this resulted in Windows booting up, so again we actually fixed this machine. The following photos will illustrate the work that we carried out for the client.
