1), when taking your computer apart, take out the battery and unplug it always
2), Remove the plastic cover piece above the keyboard, called the keyboard bezel. this is the piece where you can see the speakers. it is a bit difficult to get the plastic retaining clips to pop loose, but if you are careful, you can use a small screw driver and slowly between the two screen mounts. this is done with the screen all the way back. you could use a paper clip with a little 1/8" bend at tip to do this also. (it is a tight working area) there are three retaining clips that have to come loose the others are fairly easy to pop out . once this is bezel is off the rest is fairly simple. please take your time and be patient as if your not you could damage it .
3), Remove the keyboard. Remove the two screws that are evident once the bezel has been removed. These hold the keyboard in place. Lift the keyboard up from the screw side and the retaining clips at the front of the keyboard will lift out. (there is no need to pry here). Once the keyboard is loose you will have to either leave it connected, just off to the side, or disconnect it from the mother board. The keyboard cable connector has a black clip along the top of it. just lift this clip up a little and the keyboard cable will slide out. (the keyboard cable does not have a fixed connector, but is just a ribbon that is held in place by the black clip along the top of the keyboard cable connector) Once you have removed it you will better understand what I mean.
4) Remove the wireless card. It is the only card visible at this point. It is connected by metal spring clips. just unclip in a similar fashion as removing ram. You do not need to disconnect the wires connected to card, just move card over to expose area below card.
5)you will see C88 clearly labeled right next the jack that the wireless card plugs into. There are two little solder squares (approx 1/16") at this location. *** At this point plug the power adapter to your computer again. ***
You will have to jump the two solder squares at label C88. .use a small wire or paper clip but make sure you removed all the coating off the paper clip first with pliers so it can make a good contact on both ends. hold it in place on these two solder contact squares and press the power button to boot your computer. here is a link to guide you for disassembly it is the same family of laptops although its for a a135
