“Hie, My Laptop is having a problem. At start-up the laptop beeps once; long and two short ones. It doesn’t show anything on the screen but I can here the sound of the fan spinning.”
After I read this email from a friend I could easily guess that he was using an HP Pavillion laptop because their graphics cards always fail due to high temperatures.
This issue is most certainly caused by poor cooling design in the HP pavillion DV series Laptops.
The problem is caused by a few of things.
1. The Sticky thermal pad used to transfer heat from the Nvidia Graphics Card to the heatsink which does not do its job
2. The fan speed and internal design do not allow enough hot air to be extracted from the casing.
3. The use of lead-free solder which is more brittle and easily cracks under high heat conditions.
In fact, the poor cooling system causes the temperature inside the laptp to rise and this in turn will break the solder connection of the graphics card mounted on the motherboard.
If you are having the same problem you can fix your computer by using the following two methods:
The first one is very simple but it is for temporary so that you can copy and do a backup of the data in the computer before the problem resurfaces again.
2) wait for some time (15 min) and let it get warm
3) restart and you laptop should work.
