A friend of mine has a HP Pavilion DV7 laptop. The laptop has been overheating for some time resulting in the computer powering off. Now the condition has gradually gotten worse and he asked me to have a look. The laptop is out of warranty so I began disassembling the laptop and noticed the fan was clogged with dust, bugs and fluff. However, after cleaning the fan and cleaning the processors and reapply the silver cooling substances, the laptop did power on for a while before overheating again, again resulting in the laptop powering off. However, now the laptop will not power on (or stay on). The laptop LED light for the power supply will stay on when connected. Upon pressing the power switch the lights on the laptop will flash with the fan spinning for a second before the laptop powers off again. I've tried a cold reset (holdiing down the power button for 30-60 seconds). The problem also occurs with just the battery installed.
I'm thinking the system board has become faulty during the overheating period, and now it will need replaced. But I want to make sure it is the system board....as I don't want my friend to purchase a new one and it not making a difference. However, it does looks very likely!!
I've been reading about this brand/model and there has been so many cases of this happening - apparently a design flaw on HP Pavilion models. The laptop is only 1 year and 7 months old - you would expect this problem to occur later in its life!!
Has this problem happened to anybody else here, and if so, how did you go about fixing it (apart from purchasing a Toshiba laptop)??
