Lenovo Ideapad 320 No Power Successfully Revived

I successfuly repaired this Lenovo Ideapad 320 laptop with board id NM-B242 Rev 1.0. According to customer, they used universal charger and set to 24V causing the laptop not to power on because of overvoltage.

I check for shortage using power supply but it has zero ampere. I dismantled the unit and check if there was a burnt components, but the board was clean and shinny.

I check 19V rail. I measure voltage input of the first mosfet, it has 19V. But on the output side, it has zero volt. I thought the culprit was the 2nd mosfet. But before I checked the 2nd mosfet, i disconnected the jumper PJ301. Then measured the output of the second mosfet if it has 19V. YES, it has! Therefore the problem lies on 19V rail.

So, I downloaded the schematics, and check the 19V rail. By analysing the schematic diagram under page 53, I planned to lift PQ314 hoping that this mosfet was leaking. I lifted the mosfet, then checked 19V at current resistor PR301. Huwaw!!! 19V was there! I quickly replaced PQ301 N-Channel type mosfet. Now the laptop has been revived.

Lenovo Ideapad 120S-14IAP No Display Successfully Repaired

The customer said that this laptop was from US, and upon receiving the unit they complained that there was no display. In my thought, maybe there was a bios program corruption. That's the reason why I flashed it on my RT805F bios programmer. See images below.


Board ID: 120S_MB_V1.0

Back up first before writing.

Then write good bios bin

Now its done.

iPhone 6 No Power Successfully Repaired

This iPhone 6 has no power due to disconnection or shorted to ground. What I first did was by visual checking. I look at all capacitor that might have corrosion. But the board was so clean. I then use my digital tested to test the capacitors one by one by setting it to diode mode. I first check on the area where vcc is connected. To make the story short I figured out what was the bad capacitor. See image below. By removing the bad capacitor, the unit came back to life :)
