Lenovo 14ALC6 - NMD521 - No power, totally dead.

by Mike Russell

Machine won't power on, no power led, no fan spin, completely dead.

Checked PQ5400 - AONS32314 and pins 5,6,7,8 are 20v (AC adaptor voltage) but pins 1, 2, 3, 4 are 0v.

Following Gate Pin 4 to PU5400 - BQ24780SRUYR.

VCC 20v
ACDET 2.8v
ACDRV 0v (goes to pin 4 gate of AONS32314).
ACOK 0v
REGN 6v

According to datasheet, conditions are correct for ACOK to be high but it is not.

Tracing ACOK it's connected to ACIN which is connected to a pin GPB0 of IT8227 but also shown as connected to +3VL via a 100k resistor...

iMac A1418 - No LED, no power after overvoltage on Ethernet port

by ryogadan78

Hi guys, I need your help again.
I have this iMac from a customer that shut down during a storm along with all the other devices in the house. In particular, the router, connected via Ethernet to the iMac, caught fire.
When I removed the screen from the iMac to check the status of the LEDs, I noticed that none of them were lit. I had a perfectly compatible and working power supply, so I tried it right away, but the problem remained the same (no LEDs). With the thermal camera, I noticed only a slight warming (32 degrees) of the NCP1605BG chip on the power supply. The rest was completely...

How can I be sure that my EC chip is dead?

by double_DD

Hi all,

As the title suggests, how can I be sure that my EC chip is really dead?

I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...
