iPad Mini 2 GSM No Power [FIXED]

I got this iPad Mini 2 GSM with Retina display from my neighbor. He said that according to the owner the unit suddenly shuttled down, and when trying to charge there's no charging indicator at all. So the unit can't be charge nor can't be powered on.

I dismantle the unit. Check first if it's shorted to ground. YES! It's fully shorted. I checked the board over my microscope to see if there's a burnt capacitor or IC. I saw 2 suspected capacitors as shown on the image below.

To make sure if the two capacitors are shorted to ground. I checked with my multi-tested. But my multi-tester said that the two capacitors are not shorted to ground. So I decided to look again for suspected burnt component. I found another capacitor show on the image below.

I double checked again using my multi-tester, and it's positive. This capacitor is shorted to ground! What I did was I just remove it and the shorted was gone :)

Problem solved!

Lenovo Laptop No Power [FIXED]

This Lenovo laptop came to me with a no power, no light indicator. In short, no sign of life. I disassemble the unit and check if there's a short to ground on the charging pin. There's no short to ground. The board is clean, and no sign of water spill.

I connected the charger and measure voltages in charging pin. There's a 19V there. I measure input and output voltage of the first mosfet, also there's a 19V. I measure input voltage of the second mosfet, and 19V was also present. But when I measure the output voltage of the second mosfet, there's no 19V there. That means that the second mosfet was damage or open.

Replacing it and the laptop revived!

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!
