Hi,
I have this laptop HP x360 1030 G2.
Battery is charging well, the laptop powers on the CPU gets warm but nothing on the internal screen or hdmi.
The fan is spinning at full speed.
Any idea ?
I just asked for a schematic i cannot find it.05-30-2024, 05:25 AM -
I started troubleshooting this Razer Blade 15 laptop DA560 motgerboard a while back, due to some shorted 19v, 5v, 1v power rails. I fixed some of components and think 19v rail is good, 5v rail is good, 3v is better but not all way i think, and 1v is still bad. At this point the diode reading on these rails are 19v - 0.032v , 5v - 0.167v, 3 - 0.63v and 1v - 0.005v .
When the rails when down, I went down different rabbit holes and seeing chips getting pretty warm on thermal but not blazing hot. Yet there were not any caps or any small components getting blazing hot. Example is EC chip,...06-06-2024, 11:35 AM -
I have this 1707 with the 5V 0A power loop issue on 3 of the jacks.
One of the CD3215C00 had corrosion under one side U3100 to be precise.
This USB jack was drawing ~.2A and not boot looping.
After replacing the CD3215 I am having an odd problem. I can rotate the USB-C and it only works in one orientation. And now it boot cycles, like the other usb channels so I'm part way there.
After looking at the schematic and board view. It makes very little sense that this is happening since they both pin 59 and pin 60 both go to the same places on J3300.

Hi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.

Hey everyone,
I'm a novice trying to repair my laptop. The LCD screen has an image, but no LED backlight for the image. It also produces an image when connected to an external monitor.
I have found what I believe to be a blown inductor labeled "L4502" and "120 Ohm" in the schematics (zoomed in image, blue arrow to blown component). I have included an image of the general area of the mobo and an excerpt from the schematics as well.
I am having trouble selecting a replacement component, which I believe to be a 120 Ohm ferrite bead, from the components...06-06-2024, 03:39 PM -
Hello, I have the similar problem. My Dell Precision 7520 doesn't turn on with only battery. Below are the various scenarios and its symptoms
1. With only battery, the laptop turns on but no display and shuts down after few seconds
2. With battery and charger plugged in, the battery light comes on. But pressing the power button does nothing and laptop refuses to turn on. However, the battery led light blinks every 17seconds from when the charger is plugged in with or without battery. So whether the battery is inserted or not, the battery led light will turn when charger...Yesterday, 09:23 PM

Quick repair summary for those interested. I had a Hisense 58R6E3 TV that had backlights working but no picture. T-Con had 12V supply but some of the supplies on the board were 0V. Unplugging one of flat cables to the LCD display driver boards brought the supplies back up, so I figured it was a short on the LCD panel driver board. Narrowed the short down to the 15V power supply by checking the coils on the T-Con board to ground with a diode test and confirmed that all the MLCC caps on that rail all showed a short to ground. I injected 5V/1A into the 15V rail on the driver board (T-Con disconnected)...Yesterday, 04:16 PM

Hi,
i had a HP 640 G8 with a DA0X8AMB8E0 Board. I would Flash the BIOS, but i used a CH341A Programmer with 5V instead auf 3,3. Then I thought the BIOS was now defective. I have already replaced it with a new one (flashed the same BIOS).
With the new chip, the notebook has the same error. The charging port lights up once and then goes out again. The notebook does nothing more.
I iced the board with a cooling spray to possibly find a chip that gets hot or has a short circuit. Unfortunately, I didn't find any. I suspect a fuse might have blown. Does anyone...Yesterday, 02:47 AM
