To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...05-05-2025, 04:59 AM -
Hello,
Today I discovered that PSU Chieftec BDF-750C PSu has died. Not sure when that happened since I didn't use PC for a long time. PSU is not that old, about three years, but just out of warranty.
I had some previous success in repairing different electronic devices including PSU. Until now, the problem was usually bad electrolytic capacitors after many years of operation, but this time is different. When trying to turn on the PC, fans move a little bit and then nothing. There is astable 5V SB (actually 5.13 V DC Standby voltage), but that's it.
I tried to jump start...05-07-2025, 05:30 AM -

PP3v3_G3H_RTC_X is present - 3,3V
PP3v3_G3H_SOCPMU is present - 3,3V
What else should I check?

Long story short. i am building a fully custom car radio. and want to use a extremely bright LCD.
sadly the DGPU seems to be nonfunctional after i fixed the bios (fried voltage controller). so the Original HDMI port does not work.
you can use a EDP TO HDMI adapter to add a HDMI port as replacement to the onboard EDP LCD connector,
HOWEVER it turns out. lenovo enforces a LCD whitelist.
this means you cannot upgrade the LCD despite matching EDP specs and voltages.

This device came in due to the screen flickering if you use the touchpad or external mouse. It will flicker black when this occurs. If you use the touchscreen, the behavior does not appear. Also, if connected to external monitor, the external monitor is not affected by the flickering. I did a good amount of research on this, and concluded that it is due to the display driver. HP does not offer Windows 11 drivers for this model so I got the replacement drivers direct from Intel. I installed them and the problem...Yesterday, 12:21 PM -
Hi
I cannot find any information on an sot-23 component. It is on a USB board. The markings are 23AX
There is another sot-23 component next to this one and the markings are 1AM. I have found some information on this one but no information about substitutes
If anyone has any ideas, please tell me.

Previous owner said TV just went blank one day.
They attempted to open the back panel and yanked the power connector off the power supply in the meantime.
Easily fixed that and got the TV to turn on. Backlights come one with everything connected. Good Sign.
The mainboard shows signs of life (red light on digital audio out is on) but that's about it. Good Sign.
There is not blinking LED and the most importantly there is LED response and sound when I press the MENU button on remote control. GREAT Sign.

Laptop does not power on but has a fix white light on power button, when connected to power.
I found, while trying to diagnose, a hot spot in the motherboard and found it to be a shorted capacitor (see photo below) on the 2.5v (2D5V_S3 on schematics). After replacing it with one from a donor board, still, the board does not turn on...
The usb-c meter reads upon connection 20.1v and 0.00a, with some occasional flashes to 0.03amps. After 10/15 seconds circa, it goes to 5.2v and draws an almost constant 0.07amps. (same behaviour as before)

I hope my computer does not randomly reboot while typing this. My main system is the AsRock 970A-G/3.1 motherboard with the AMD 8150 chip. I am experiencing FREQUENT and RANDOM reboots once the system is used for a couple of hours (sometimes it reboots before I even get to the Win7/Linux Mint dual-boot screen). The problem MIGHT be the DRAM controller chip (I recently upgraded to the maximum 64 GB RAM). It also might be the VRM chips. I am using a typical aftermarket CPU cooler, which does NOT blow air DOWN onto the VRM heat sink.

Hi guys I have this dell that with the battery charged it turns on correctly, but if I connect the charger I get the charging symbol but it doesn't charge the battery.
I found the shorted charger PU4401 ISL9538h that had pins 14 and 15 shorted and I replaced it. but it still doesn't charge.
I noticed 2 things:
1) without the battery connected if I connect the power supply, on the SDA and SCL pins of the battery I have 0V I measured the resistance with ground and it is very high, if I connect the battery I have 3v on the 2 lines.
2) if I try to turn it on without the battery...05-06-2025, 06:19 AM -

Hello,
I have a Lenovo Yoga C630-13Q50 Windows on Snapdragon laptop that I bought used here in Japan. They only sell the 4GB RAM version here in Japan so I decided to purchase an 8GB motherboard off of Aliexpress. The motherboard works without issue but Product ID, MTM, and Lenovo SN entries in the BIOS are INVALID.
I would like to input the values from the old motherboard. After searching the internet I learned about LVAR and have tried to use it to input the values but I get the following error.

Hi there guys i have this laptop that doesnt power on. When i plug the charger i see 2 white blinks on the front leds with a small delay. If i press the power button the led ligts up for less than a second then dies down.
When i plug in the USB AMP meter on the Type C i get 20v and a jump up to 0.34A then the value changes to 5.02v 0.03-5A. Please if someone could guide me on how to troubleshoot and possibly fix it. i am new into fixing boards so this will be a valuable lesson to me.
Thank you in advance guys .05-06-2025, 10:05 AM
