Recently my notebook has been giving me a lot of trouble. When I run too may applications, or sometimes when I’m watching DivX shows, the CPU will suddenly slow down. I can feel hot air coming out of the exhaust port When I place my hand there.
Well, I guess it was time to give the cooling system a cleaning.
If you own a Dell Inspiron 5100 notebook, you may need to do this periodically. Otherwise you may find that your notebook will overheat and shutdown unexpectedly. An alternate solution is to download software that allows you to control your cooling fan. However, the best way to solve this is to clean the fan. The weakness in this notebook model is the ventilation fan cannot be accessed from the outside. You have to take apart your notebook.
This is a step-by-step guide for cleaning your Dell Inspiron 5100 ventilation fan. Warning: This voids your warranty. Warning: Don’t do this if you don’t know what you’re doing. Warning: Watch out for static discharge! Warning: Turn off your notebook before attempting this. You can print out these instructions first or write them down.
Step 1: Lay your screen flat. Make sure you do this with enough lighting.
Step 2: Use a screwdriver to pry open the blue panel. There’s a little opening at the right hand side of the panel. (Pardon the dust)
Step 3: Use a screwdriver to remove four screws that are holding the keyboard down. Make sure you keep all the screws in a safe place, and group them together so you don’t mix them up.
Step 4: Gently flip back the keyboard to lie against the touch pad. Watch out for the cable connecting the keyboard to the motherboard. Don’t break this cable. (Notice how I’ve cleaned the dust from the monitor). You should be able to see the cooling fan on the right hand side. See how dusty it is!
