Re: Lenovo IdeaPad Gaming 3 (15ARH7) - HLG50 LA-M082P rev. 1A
all of them have about 19 Ohms to GND. The third coil from the left is clearly the one connected to the controller I removed. I'll order a controller and update when I have it replaced

Re: Lenovo IdeaPad Gaming 3 (15ARH7) - HLG50 LA-M082P rev. 1A
You're a life saver!
I was surprized too that it P.O.S.T.ed, and even showed the boot menu of my USB drive. I couldn't find schematic, so I have no idea what's its purpose...
Thank you big time!...

Lenovo IdeaPad Gaming 3 (15ARH7) - HLG50 LA-M082P rev. 1A
Hello. I have the laptop of the title for which I can't find any info at all...
It suddenly stopped working (no power at all).
I located a chip overheating and by removing it the laptop POSTed, but (not suprizingly) did not boot into OS.
The problem is that the said chip is something I have never seen before and couldn't Identify it.
The markings are MPPD 8694 1456 C
Any help would be really appreciated.Thank you in advance!... -

Schematic for Toshiba L675 (Compal LA-6042p) needed
I have searched everywhere without luck.
Does anyone have a schematic for Toshiba Satellite L675-11G (Motherboard is Compal LA-6042P rev 1.0)
Thanks in advance! -
Toshiba P200D not power on when plugged in
Hi everyone!
I have a pretty strange problem with a P200D (Compal LA3831P motherboard): While it turns on just fine on battery, it does not when plugged in (even with battery connected), BUT, the thing is that the battery charges and if I plug it in while turned on, it continues working.
To the details now, the power button does not have 3v as I expected but around 10v when on battery and 16v when on AC. After pushing the button (thus grounding this voltage) it goes near 3v for a few seconds then returns to 16v (if it turns on, it stays at 3v).
Any ideas?

Re: Motherboard schematics archive?
Well, I'll put a bunch of files I've collected, but I don't have time to cross-check if already uploaded.
Great idea btw!

Best guess is a shorted capacitorLeave a comment:

Re: Toshiba L650 power problem
At the end it didn't work. I'm still trying to figure out a way to make this thing usable again.
Thanks for your answers!Leave a comment:

Re: Toshiba L650 power problem
I have read this post, in fact, I have replaced a couple of proadlizers with capacitors successfuly, but it is irrelevant with my question.Leave a comment:

Toshiba L650 power problem
Greeting to everyone!
I have a Toshiba L650 that works perfectly good on battery, but does neither charge nor work on external power. I have attached the schematic of the power supply part of the board, so I cut to the chase.
After some experiments I probably destroyed the charging chip (MAX17435ETG+)
but it still works the same (even with the IC removed).
I get 19v to the Drain of Q6002 (with adapter on but battery removed) but only 3v on the Source and nothing to the gate (same as before destroying the IC).
With battery on, I get 12v on the source... -
Re: acer 5920 g blinking power adapter
Thanks a lot guys, I just fixed another 5920g, the bad capacitor was PC24, located next to the drive connector on the top side of the PCB.
ps. the info about the modem was a savior!!!
