        Try ShopJimmy.com, or Ebay. Just be careful when buying from ebay, look for good seller with a return policy.

            Check them for shorts. Typically, they are MOSFETs (3 legged devices.) You do not need to remove them from the board to do the test.

            To test for shorts, use the same mode on your meter that you used for fuses. Except this time, a reading of near zero is bad. Test all three combinations of pins (pins 1-2, 2-3 and 3-1) the polarity does not matter for a quick check like this.

            If you find a device with more than 3 legs on that heatsink, please advise the part number printed on it so we can indicate where to test.
            hi hello! my name is Al. I'm sorry for the interruption. I'm also having the same issue, but mine reads .5 and 1.5. I'm new to this too. Is mine bad too with those readings?

                Same basic steps...Do you have soldering experience ?
                IF NOT, it might be easier for you to replace the board !

                    Asus Probook P5440UF-XB74 power issue
                    by GLISIT
                    Hi all,

                    TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                    I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                    A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                    Samsung Plasma TV Power Supply Issue
                    by lp20th
                    I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up. Upon investigation, removing feeds to the other boards within the TV it was found that disconnecting the logic board from the power supply allowed the...

                    Acer Spin 1 SP111-33 Power-On Issue (Troubleshooting Assistance)
                    by justice171
                    I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.

                    Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:
                    1. Verified that all critical voltages are present:
                      • 3.3V and 5V are always present if DC is plugged.
                      • 1.8V on the BIOS chip is present.
                    2. Checked the power button functionality:
                      • When pressed, the voltage drops to 0V, indicating the button is functional.
                    3. Inspected the flex cable connecting the USB, audio, and power button to JUB1:
                      • Confirmed connectivity is intact, ruling out issues
                    ...

                    lenovo flex 5 14itl05 power sequence issue
                    by claws77
                    hi guys, my motherboard will not start no matter what
                    when connected to ac power, the battery does get charge, led indicator glows red when discharged and turns white as it is fully charged.
                    but rest nothing happens no sign of life.

                    this laptop has one preexisting usbc power issue - so i use DCIN jack for charging my laptop.
                    with this issue my laptop was unable to power ON only sometimes i just had to wait some time.
                    but now nothing happens no matter how much i wait/ charge/ press and hold power button.

                    i have no knowledge of motherboards ....

                    Dell G3 17 3779 Weird power cycling and shutdown/restart issue
                    by SuperJames
                    This one's a weird one, and still unsolved despite it having gone back to Dell once.

                    Specs

                    i7-8750H, GTX 1060 Max Q, 500GB SSD & Seagate 7mm 1TB HDD. 17.3 IPS screen. This has the fingerprint reader in the power button.

                    Backstory

                    I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...
