schematic diagram and Board view for LA-M653P, Please

by vincent999

I had problem with "Ideapad slim 5 16ABR8"
I believe 19V power line is shock to ground. M/B is not charging from Adaptor ( Adaptor is good ), Not sure about Power Jack but I like to make sure before changing the power jack. Laptop is on with battery but hot to touch near batter connection (Please see pic). I don't repair this board before and I'm beginner. Try looking for schematic and board view online but still no luck. Schematic or other help would be greatly appreciated.

Thanks

Dead LA-H323P (no light) - HP 15-DW

by Patan

Need help here...
I'm new on the forum and I'm not professional in electronics so i ask sorry in advance for eventual errors...
As title says, i have a LA-H323P dead.

Now, little background.
The computer was working fine, just seems that the cable of screen was dying because it had the classic color problem, sometimes green, sometimes violet, sometimes perfect, but anyway working.
When i opened it the battery was so fat that was seriously near to explode.
So i removed the battery... and turned on the notebook... that was, again, working perfectly fine....

Pioneer amplifier A-205 Relay not clicking after a mistake i made

Hello guys
Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing...

Hello, I am looking for any and all files related to the mainboard for 820-2565-A (13" Macbook Pro A1278 mid 2012) schematics/board view.

I looked through forum search results and google and was unable to find a board view file, I found a pdf of all the schematics but I don't know where the parts physically are on the board as this is my first macbook board level repair attempt.

The macbook charger has a green light, the battery has been replaced and OS reports Normal status but Not charging. After cleaning a corroded capacitor it crumbled off the board. There...

I have a KD-65X9005A Sony 4k LED TV.

ASUS ROG STRIX GL702VSK no power issue PQ8901, PQ8900?

by ub6ib969

Hi,

working on a ASUS ROG STRIX GL702VSK 60NB0DZ0-MB1260 that does not power on. At the PQ8900 PIN2 (P_CHG_ACMOS_G_20) I am receiving 24.7V and PIN1 (P_CHG_ACMOS_S_20) 20V, however when I place the PQ8901 P_CHG_ACMOS_G_20 it drops 0V. I don't have the replacement mosfets ( N-MOSFET QM3058M6AC PRPAK5*6
UBIQ) however will any N-channel mosfet with similar parameters work ? I also found that PCI8703, PCI8701 are shorted. any help would be grateful.

ASUS GA401QM No ACDRV, No CMSRC

by ResoluteHawk

I have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.

When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...

- Only sigh of life is beeping when touching the capactive buttons on the front.

Diagnostics so far:
Checked the PSU output voltages:
12V present
5V present altought its only around 4.2V
3V is present measured 3.4V.

I check TP 202 which is for the short circuit protection: 0.606V on diode mode
