          It would help if we knew the make and model number, without that don`t expect too many replies...

                    Surface Pro 7 type 1866 PD controller firmware issue
                    by titomno2
                    Hi guys,

                    Hope you are fine.
                    I'm struggling to fix a small issue with one of the tablet Surface Pro 7 type 1866 i'm fixing (windows 11).
                    The boot time is so long (up to 5-10 minutes).
                    After several attempt I finally find one thing is not right (PD controller firmware is 0.0.0 it can't update to 3.6.1) under device manager I have a yellow mark, code 14 and error as decribed on picture attached.
                    I don't find any information regarding the error code 0x1803 (and sometimes it change to 0x1804.
                    In the past I have found that if the update is a success, the boot...

                    Hey everybody, got a strange one here.

                    The TV will display the Home Screen, Menus, Netflix Home Screen, YouTube home screen with preview tiles, etc, without issue. As soon as I try to play video (streaming or from any of the HDMI inputs), all I get is audio and and blank screen. It's like the video is not being processed. So I ordered a replacement main board. I can now play video from streaming sources but the video from HDMI sources is all green (kinda like photo negatives but all green) and the audio does not work. Is it possible the main board I ordered is also failing?? I can't...

                    Optiplex 3050 micro 2 blinks followed by 3 blinks issue
                    by Taurus12
                    Does anyone have an idea of what might be the issue with my 3050 micro? I have tried replacing new cmos battery but still the same

                    I am not sure if its the powersupply that I'm using is the issue since its the original powersupply. its a laptop powersupply with the same specifications with the 3050 micro so i guess it should be fine.

                    i also tried replacing the bios but with no avail, everytime i try another bios it gives a different blinking lights

                    Any recommendation on what I have to do next? Thanks in advance

                    Victrix pro bfg ps5/pc controller - battery issue
                    by bociub
                    Hi there

                    So, here is a controller which has 2 batteries, their connectors on the right side. The controller does not work wirelessly and if I try to switch on it lights in red until i release the button. Furtheremore, I beleive that it never ever worked wirelessly. The voltage on the batteries (between a-c and x-z) are 3.8 volts and if I connect it to a charger it flashes one green.
                    however the voltages on the middle pins are different and I cross tested the batteries and it was same so the issue is going to be with the board itself. (i beleive so)

                    So, between...
