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!

ACER Core i3 Blinking Display [FIXED]

The only solution for this blinking display if the LCD panel is good is to flash the BIOS. I used EZP2010 V3.0 Bios Programmer.

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!

ASUS X551MA No Display [FIXED]

This ASUS X551MA comes with a no display on the screen. I fixed it via BIOS Flashing.

Lenovo Laptop Blurry Display [FIXED]

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! :)

Sony Vaio E Series No Power [ FIXED]

This Sony Viao E Series comes with a no power issue was very easy to fix. It has a missing 19V on charging pin output, so I checked the charging pin connector.

Problem solved.

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!

Sony Vaio E Series Laptop Hinge Repair

I use epoxy in repairinig the broken hinges. See picture below.

Toshiba Satellite A205 No Display [FIXED]

This Toshiba Satellite A205 comes with a No Display on screen. When I disassemble I saw the NECTOKIN ic which is commonly know as the culprit if the laptop has no display. I just remove it and replaced with a modified 4 pcs capacitor.
