Both memory modules, wireless card, cooling and and hard drive can be accessed from the bottom. Pull the hard drive to the right side until it’s disconnected from the motherboard. My Aspire 5100 had a 80GB 5400RPM SATA HDD installed. Grab the antenna cable connector with your fingers and unsnap it from the connector on the wireless card. Spread latches on both sides of the wireless card same way as you did with RAM modules. When the wireless card pops up at a 30 degree angle, pull it from the slot by the edges.

Question type: Maintenance & Repair I have a loud knocking noise coming from the engine .

I've put 8,500 miles on it and it just started knocking. I have read a lot about piston slap and knock sensors, etc and not sure what the next step is.

answered 5 years ago for a piston slap you need to pull apart the motor and possibly either re-bore the cylinder with the bad piston or replace the entire block be cause of the damage done to the piston and the cylinder as the piston "slapped" against the walls of the cylinder most likely gouging the cylinder walls answered 4 years ago You need to tear down the engine.

In the next article I’ll explain how to remove the screen.

First of all, make sure the computer is turned off, the power adapter is disconnected and the battery is removed. If you are replacing the hard drive with a new one, you’ll have to transfer the mounting bracket to a new drive.
