    Dell Inspiron 3420

    Hi dear all,

    I have a problem in Dell Inspiron 3420 Laptop. If i removed CMOS Battery and plug the adapter to laptop without pressing power button it will power on and boot normally. But i cant power off it using Power button. If CMOS Battery installed and plug the adapter, Laptop not working (No LED, No power) I can't power on this laptop using power button.
    I have checked power button connector. It have 3.52V and it is going to 0V when pressing power button.
    Please tell me what i have to do?

              Bios: 1.9.0

              When I received this , it would only flicker on the KB backlight for a second, then off and on.
              Then it started getting weirder!
              Sometimes when attaching the AC power supply, and pressing various pre-boot diagnostic keyboard keys... it did try to boot, in fact out of a hundred attempts, the laptop did actually boot into the Bios ! but never has...

              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...

              Dell Inspiron 7506 2-in-1 HELLCAT 19859-1 - No power
              by Scaff
              Hi all,

              I've had trouble with the power on this device since I got it. It always shut down with no warning and would often fail to power up. Dell's advice has been to disconnect the power and battery, wait, then reconnect and boot. Letting the battery run down completely also helped. I had them come out at one point and they said they replaced the board. This helped for a while but then it just stopped powering on. At this point it's well out of warranty. I missed the chance to get them to come out again because life. Current situation is it shows zero signs of life with both barrel...
