    HP 650 g2

    Does anyone know where is 3.3V formed on this kind of laptop?
    I have not working HP 650 g2 laptop and there is only 2.7V, instead of 3.3( before I push the power button)
    Thank you

      Find the motherboard model number silkscreened in white, then search for a schematic.

          The reason I asked about 3.3V rail was the fact I could not find the complete schematic.

          So I hope someone will know details about 3.3V rail at least or help me to find the source chip on my mainboard ( experts here may provide hints to a newbie how to)

          The mainboard is CIRCUS-6050A2723701-MB-A02

          Thanks again for help

              Probably the coils down near the RTC battery. But found this, may help.

                  Lowest possible resistance on laptop motherboard rail - Guide Table request
                  by Nagy Daniel
                  Hi, I'm Daniel, and I'm new to the world of repairing motherboards.

                  I would like to create a table, or more likely a guideline about the voltage rails and their possible resistance rail.

                  I know that the motherboard design has a very big depend on the rail's resistance, but I would like to know what is the smallest value for a rail that can be acceptable. For example, I heard that some new gaming motherboards can have 0,5 Ohm resistance on the GPU rail, but on an older type, it could be a sign of a shorted GPU rail.

                  So, I generated a table with AI so I can...

                  Lenovo Thinkpad L480 : 3VALW rail shorted to ground, but I can't find the shorted component
                  by mkdj
                  Dear all,

                  Laptop is Lenovo Thinkpad L480 (boardview can be found in this badcaps topic). When pressing the power button the LED power light turns on, but nothing else happens.

                  I removed the motherboard, checked for shorts on the main inductors. I found that there is a short to ground on the +3VALW_P rail (@PL201). I soldered a wire on the PL201 inductor, and I injected up to 1.3V with my power supply. Current drawn is approximately 3.2A.

                  I used a small thermal camera to locate the shorted component. But nothing on the board heats significantly, except the...

                  Looking for tools to find mainboard equivalents
                  by Jun Alithis
                  Hello!

                  I work in TV repair and often need to find equivalent mainboards for replacements. I was wondering if there are any programs, services, or websites that can help streamline this process?

                  If you're using anything like that, I'd really appreciate it if you could share your experience. Also, if you manage this task manually, I'd love to hear about your approach.

                  Thank you in advance for your help!

                  Lenovo Thinkcentre tiny M90Q gen 1 - no 12V rail
                  by lefetylorant
                  Hello Everyone,

                  Long story short, I got this unit for very cheap.
                  I've started to experiment with it's BIOS, as I did before successfully with an M900. However my very bad quality SOIC clip broken while dumping of the biosof and it must have damaged something on the panel, because it does not turn on, and does exactly nothing when powered. The maximum voltage that could have affected something is the 3.3 or 5v from the IC clip, because the unit was not powered while the bios dumping was in progress.

                  I've performed some measurements:
                  - 20V rail perfectly...
