Having problems with your PC Laptops ?

The connection where you plug in the power on my compact presario R3000 laptop is broken. The female part that you plug into is loose and probably broken away from the solder on the mother board it self. I can hold the plug in and move it to charge the battery, but as soon as I let go it stops charging and the computer shuts down. how do I take it apart to resolder the connections?


Answers :

Before you pull apart your laptop, check the male connector and power cord of the adapter, check it with a multimeter and or plug it into another Compaq. You could have a broken wire in the power cord, it could save you a lot of work.

\015\012To pull apart the laptop, remove the battery, hard drive and CD drive first.
\015\012Then remove all the screws from the bottom of the laptop, plus the screws on the back that holds the LCD's hinge to the laptop base.
\015\012Take a note of where the screws come from, some may be shorter that others.
\015\012The remove the keyboard (the screws should already been removed from the bottom of the laptop).
\015\012Carefully remove the plastic cover next to the base of the LCD screen, This may also cover the hinges, if necessary fold the screen flat to enable you to carefully pry this cover up and off.
\015\012The plastic top cover is clip fastened to the bottom of the case, carefully prize apart from one side and gradually work around the other sides.
\015\012You can now remove the LCD, there are two connects attached to the motherboard, unclip these.
\015\012The motherboard is under the keyboard and plastic top cover, there are screws securing it to the plastic base, remove these and you should be able to free it from the base.
\015\012Now you can solder/fix the power connector.
\015\012I suggest you use a temperature controlled soldering iron.
\015\012
\015\012Don't use too much force, you might crack the plastic parts.
\015\012Best of luck and have fun.
