    first check +V3.3A_RTC RTC_RST# after check RSMRST# should go 3.3 to 0V when press PWBTN depends on the platform & LD05 LDO3 ?

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              HP Probook 470 G4 - Power and Charging Problem
              by Scoff
              Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
              Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...

              Dell XPS 13 9370 Laptop, No power, not charging
              by rob_hen
              Hello!

              This is my first post for help, and I am quite newer to board repair, so bear with me.

              I have this board here (LA-E671P), with no power, and doesn't charge. No lights come on when plugged in.

              After visual inspection of the board, U22 is obviously blown up. This is the for backlight, and there is no shorts present after removing the chip and replacing.

              There is 3 USB C ports to power this board, USB 1 gives 20V, while 2 and 3 only give 5V.

              My observations using USB 1 at 20V (0.075A draw on Ammeter, slowly drops from 0.136A)...

              Help please..Lenovo ideapad 5 14itl05 power and charging problem
              by Dr.d
              I have a lenovo ideapad 5 14itl05, board LA-K321P, That will only power up on Battery only, or with battery disconnected and power adapter only. If battery is connected and usb-c power plug connected. It only works on battery and will not charge. I can however force it to charge by connecting the battery from a disconnected state while the power USB c plug is powering the laptop.

              Additionally....to add to this strange situation. The usb-c power plug ONLY works to power the laptop on one side when inserted into the boards power usb c plug. If you rotate it 180 degrees, the board gets...
