Hi everyone,
I have a Compaq Presario CQ56-115DX Laptop. The laptop has Windows 7 installed on it. I tried to clean the vent and cooling fan with a hair dryer. Before cleaning it with a hair dryer the fan was making a clanking sound. Though after cleaning it the cooling fan does not work at all. I keep on getting an error code of: 90B. What can I do?

Thanks,
Dylan

If the machine is out of warranty; open her up and see if any crud is lodged in the fan that keeps it from spinning.

Here is the manual, go the Removal and Replacement Procedures > Component Replacement Procedures. It has a really detailed step to step instructions. Please be really careful when you do it.

Unless you have a massive hair dryer I don't see that cleaning out the built up dust in a laptop. I own a repair shop and 90% of the laptops we open up are clogged bad with dust -- blowing the dust back into the machine only makes things worse, as usually the dust just blocks the fan movement.

The clogging that I also see is one reason I don't recommend laptops as a desktop replacement.
