    Help I want to ask about HP 840 G1 6050A2560201 MB A03 laptop components

    I have a motherboard 6050A2560201 MB A03 which is missing one component, which is as shown in the picture below



    then I tried to look for references on the internet and got some information, that apparently the missing component is as shown in the image below



    and the information I got from the schematic is that the missing component is a resistor as shown in the picture below



    but this information is still not enough for me, please help to determine what components are missing and what are the specs like? how many ohms? what type? I'm looking for a replacement

    Thank you for the help

      Hi. It should be fine to just short the location with a solder blob.

      From my understanding you have 2 rails that can power the VCCIO.

      One rail will be active when the logic board is awake = main power rail.

      If the logic board is in sleep mode, the main power rail will disable and the always on, lower current rail will be switched to power the VCCIO pins.

      The VCCIO pins need to be present to perhaps power devices like a mouse -> when the mouse is moved, the logic board can then wake up again.

            Huawei D14 dah98ambad0 rev d please help identify Missing components

            Hello I just bought this laptop to be used personally (that I'm currently trying to repair.), I am aware that liquid (gravy) has been spilled in this area before. but there are missing components it it possible to have a board view or a schematic of this? or just an idea on what components its missing?

            as far as I know this parts are connected as sense or enable.... that's how far I know...

            Images attached:
            the picture of the area. and some of the pinouts that I noticed on the chip...

            Xfx RX470 - Missing components
            by Artakozu
            Hi, I'm new to this forum.
            I recently bought a damaged XFX RX470 for around $10-12 USD. As you can probably see, I believe the only issue is some missing components, likely due to a scratch or a fall.
            Can anyone help me confirm which components are missing, and specifically, tell me the value of capacitor C502?...

            DJI Mini Pro 3 missing components near camera connector
            by summerwhite
            I have a DJI drone that is not displaying a video feed anymore after a repair.

            When tearing down the DJI drone to fix the armature there was some hot glue next to the camera connector that i had to remove.

            Now there are missing components either because they got pulled off or because they where never placed.

            I have two reference images from XXZ and a photo of mine.

            I'm truely hoping someone has another DJI Mini Pro 3 that they can help me identify what these components are and if they are necessary.

            On the board view from XXZ they...

            HP 15-cs3055wm - DAG7BLMB8DQ REV:D - Missing Components - Fan Error
            by grimacelord
            Hello,

            I have an HP laptop here (model and board model in title) that powers on with an error message about the fan not working properly and needs to shutdown. The thing is, the fan is spinning just fine. I disregarded the message and continued to boot into Windows and loaded up OCCT to look at temperatures and the OCCT was reporting that the CPU was very hot (98C) and climbing, so I shutdown the computer, did a CMOS reset and checked then thermal paste and heatsink for dust build-up. Paste looked good, but I cleaned it off and applied fresh paste anyway and blew out the fan from...

            MSI 1660S Ventus missing components
            by Caspar
            Hi all, I accidently knocked off some components on a MSI 1660S Ventus while trying to remove the heatsink to repaste the GPU. The missing components are located on the top left corner of the GPU. Does anyone happen to know what the values of the components are? I circled the missing components in the provided picture. Any help would be greatly appreciated.

            Thank you!

            PS If there's a boardview, that would help as well!...
