Dell Studio laptop with model PP33L has a touchpad problem-solved.
A Dell Studio laptop with model PP33L has a Touchpad problem. The problem was buttons (Right click , Left click ) have no respond to click.
I guessed at beginning the problem was software, the driver is not working or the options of buttons were off. I installed the driver again and configured the touchpad correctly but the problem not solved, at this time I decided the problem is a hardware problem and not software.
1- I removed the flat and keyboard.
2- In this model the touch pad circuits in the top plastic cover, so I removed all the screws from laptop backward as shown below.
3- I checked the flat cable to its connectors place it was ok.
4- I removed the buttons only from its place as shown below.
5- After i have removed the buttons, i began to check the buttons’s tracks, i noticed the tracks were open. I soldered it carefully with thin wires as shown below. I checked the continuity of the tracks by my analog meter set to x1 ohm the tracks were ok.
I fixed back all the things and started the operating system and the buttons worked perfectly good.
