My old and precious dell laptop was overheating but it was working. One day I decided to clean the fan because I notice the whole cooling system was clogged with stuff. I removed the cooling system where the fan is attached then I put everything back. After that my laptop did not boot anymore. If I move the cooling system to the lock and unlock position sommetimes the the two lights in the front panel go on a little bit then they go off, some other time only fan runs. I cannot afford to take it to a technician or to buy a new one that´s why I desperately need your help.
Could you please help me with this issue?
