              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...

              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...

              Lenovo IdeaPad Gaming 3 15ACH6 - no power
              by gleniu
              Hi, I have a problem with a Lenovo IdeaPad Gaming 3 15ACH6 laptop. My nephew asked me to replace the charging port because the laptop wasn't charging. This issue had happened in the past, so I knew that replacing the port was only a matter of time. Until now, my nephew managed to deal with the problem using a temporary solution: bending the positive metal tabs inside the port with a thin tool. However, this had stopped helping for a while. Today, I replaced the port – and to my surprise, after the replacement, nothing happens when I plug in the charger: the power LED doesn't light up, the laptop...
