HP LA-C701P REV 1.0 does not trigger after shutdown. However, when we remove the adapter and plug it in, it gets triggered.

Re: HP LA-C701P REV 1.0 does not trigger
1) is the power adapter the original and recommended model for this unit ?
2) see attached -> measure the voltage on the 2 x DCin mosfets used by the charger IC to power the logic board.
Meter in DC volts mode (30v or higher is ok).
Red meter on each pin to test; black to ground.
Check source (1-2-3); gate (4); drain (5-6-7-8) of each mosfet @ PQ202 & PQ203.
Post each measurement for a review.Attached Files -

Check voltage on power button.Comment

thanks everybody
PM_SLP_SUS# did not exist. We noticed that there is liquid contact on the motherboard. We carefully examined that area. We noticed a disconnected line on the back of the CPU. We repaired the line. that is all.Attached FilesLast edited by simabilisim; 10-01-2022, 04:34 PM.Comment

Hi fellows,
I am trying to repair a Dyson DC45 battery powered hoover.
There is a trigger board in it which hosts an Attiny48 and some power stage to drive the brush motor.
Unfortunately a SO8 component burned to hell in it together with a 0603 resistor and the IC could not be identified.
The Attiny output looks to be survived the problem because when pulling the trigger it outputs high for a while and then turns off.
It is likely that it measured the current on the R10 shunt and this is why it is shut down.
I have attached... -
Hi Ideapad when Plugged in 3.3vALW and 5vALW are on, but 1.05vALW and 1.8vALW absent. Power led lights and remains always on and laptop not trigger..
Found a burned spot on LV5075B IC, replaced with a new imported IC, but 1.05vALW and 1.8vALW still failing. .
EC IT8586E working voltages and signals are all ok except PBTN_OUT# 2.44V not changing when power button is pushed and EC_RSMRST# always 0.1V ??
Reflashed EC IT8586E and Main bios with newly download dump from Lenovo site to no avail.
Should I fix again a new L5075B and replace IT8586E to solve the issues.... -
Hi all! A bit of an interesting and unusual problem: as the the title suggests I have a Hisense H50N5300UK that reboots when showing fullscreen solid red images (and some other solid colours, but red generally causes the issue the fastest). I first came across the problem assuming it was an intermittent issue, but later lucked into finding out that a title sequence of a show I watch happened to trigger the reboot.
What happens:- TV appears to operate normally, for an indefinite amount of time until a problem image appears
- The problem image is displayed very briefly, then the

I'm new to BoardReader and schematics.
I did, however find a schematic for my board here:If I trigger a system restart by shorting CC20 to ground, system memory is wiped clean (Memory dump is mostly: AF AF AF AF AF AF hex values).Code:https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/schematic-requests-only/91332-la-j801p-schematic-acer-a315-56
However, if I click restart the machine via software, artifacts persist in memory and there is no AF AF AF at all.
This leads me to...08-21-2024, 08:14 AM -
I have a nacon controller which has some fancy RGB ring (4 RGB LEDs). 3 of 4 leds are not good and I am looking for a replacement. The size I measured is 3mm x 2.5mm and it seems a 3528 led would fit fine, and it's in common anode. But I am not sure what wattage it is. I have attached photos of led and driver ic (ak63rq1 I think).
Also one of the triggers is malfunctioning sometimes, I don't know what these pots are called. I measured across the 1st and last legs (in circuit) seems to be 1.1kohm pot. I found some xbox controllers have this but they are 10k. Any info?...
