        Schematic: http://www.s-manuals.com/motherboard/quanta_r22

        Check the CMOS battery voltage. On page 12 of schematic, check all caps ,resistors,diodes on +AVBAT .Check Y3 xtal .

                              i think flashing bios can solve ur problem

                                        Problem with LG Plasma 60PM6700 - Random power downs
                                        by theone111
                                        I have an LG Plasma TV 60PM6700 for the past ~12 years.

                                        In the last ~3-4 months I have been having some issues.
                                        1. Problem: It started with random picture disappearing (sound still worked).
                                          Frequency: Happened about once a week.
                                          Solution: Had to turn off TV wait a few seconds before turning it on again.
                                        2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                                          Frequency: Happened about once a week.
                                          Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                                        3. Problem: TV shuts down
                                        ...

                                        Thinkpad W541 (20EG) Q1, weird behavior after SPI flashing (3 flashes of power button LED)

                                        Hi,
                                        I kindly ask for help with Thinkpad BIOS/ME repair.
                                        Thinkpad W541 board bought from Aliexpress, so I have no service tag nor S/N. It is 1GB version Q1 (K1100 nVidia GPU). BIOS 2.23, EC 1.13, ME 9.1.32.1002.
                                        It worked fine until I tried to remove whitelist.

                                        Steps taken:
                                        - battery out, CMOS coin cell out, laptop disassembled; I kept LAN/USB subboard connected
                                        - i took SPI programmer (CH341A with 3.3V mod) and SOIC clip and did a full backup of all SPI flash chips (SPI1 and SPI2 - BIOS, EC, ME, GbE; SPI3 - video BIOS; SPI4 - Thunderbolt fw) for several...

                                        i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
                                        The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

                                        by HTR-Informatique
                                        Hello,

                                        YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

                                        I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

                                        On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

                                        I also changed the screen because the PC fell and the screen was broken.

                                        I changed the battery with a new and original battery.

                                        I also had corrosion/oxidation on the...
