So my laptop recently made a weird noise and a message appeared that there was a cooling system issue (I think a piece of the blade came off or something came loose. Its about 4 years cold now.) I want to repair this myself to save sometime from going all the way to my brother's house 4 hours away for a free professional repair, however, I'm nervous about dissembling the laptop because I'm scared I may hurt it somehow. I need to know if I can somehow check the fan of my Satellite C55t-A5222 without removing keyboard. There are only a handful of dissemble videos. I'm also looking for how to clean a G56 HP laptop's fan if you have any information along the same lines as the previous statements.
