This Lenovo laptop has a blurry display. After I disassemble I found out that the ground of the end flex as shown in the image below has been disconnected.
Re-soldering it to ground fixed the problem.

Dell Laptop No Power Done
According to the owner this laptop suddenly shuts-off while using. And she(teacher) smells like burning.
After disassembling the laptop I found out the burnt flex show in the image below.
After removing the burnt flex, the unit still dead. So I measure voltages, check burnt parts if ther's any by check the components one by one. And I found none.
The only thing I did to revive this laptop is to remove the bios battery and short the positive and negative terminal from the board for about 30 seconds.
After that, the unit comes to life! :)

Toshiba Satellite L305 No Display Done
It's another toshiba satellite laptop that comes with no display. As usual if there's a nectokin ic, that's really the problem. And if you don't have a brandnew nectokin ic, just modify it using a 4 pcs capacitors with 330uf.
Toshiba Satellite L655 No Power [FIXED]
The reason why this Toshiba Satellite L655 can't power was the owner used a universal power adaptor with 20volts output. When I disassemble the unit I saw on its charging circuit the protection diode connected in parallel with the positive with respect to negative. I am sure that this diode was the culprit. Because of the over voltage the diode became shorted, causing the 19V shorted to ground.
I just remove the diode and the laptop was revived!

Acer Aspire One D250 Power Problem
When I connect the charger the orange LED lights up, and when I press the power on, the yellow LED beside the switch blinks. And eventually the orange light will off.
The first thing I do is to find corroded parts. Maybe there's a shorted capacitor on the board. Luckily I found two shorted capacitor :)
Removing the two capacitors solved the problem...
