    Dell Inspiron 17R-5720: No Power - No Lights


    Hello everyone. I'm currently working on a friend's Dell Inspiron 17R-5720 running Windows 8. The LEDs on the front (Status, Loading, Battery, WiFi) are all off, even when battery is installed, and AC adapter is plugged in.

    I've checked his AC Adapter with a multimeter, and it shows it's giving off the correct amount of power. I've also tried a working charger from another computer, and it's still not being recognized. I did a bit of troubleshooting before taking it apart, thinking it would be the laptop's DC Jack, so I went and replaced that, only to find it still is acting up. I even tried to take the battery out, and plug it in just with the AC Adapter, but no luck.

    Now I did get it to power up once (with the battery installed) for a few seconds, with the message, "this battery is temporarily disabled" as shown in this thread. I powered it down, but it refuses to power back up again. I don't want to say it's a bad motherboard, but that's what I'm starting to believe it is. Has anyone else experienced this before?

    Thanks!

    Did you try with AC adapter only (battery back removed), I have run into few laptops that would not start with bad battery. ?

    Try removing the battery and power adapter and hold the power button for about 60 seconds.

    Yes, tried it with just the AC adapter (tried two identical chargers) but no luck.

    I have also tried this, but no luck.

    I'd start pulling components, HDD, DVD, etc and try to see if you get power. Then memory, then start ripping it apart and reseating all connectors and looking for any burned spots on mobo. Last one I did I found they had spilled a soft drink in it.

    Before you rip it apart, make sure it isn't still under warranty.

    Checked the warranty, it's been expired since 2013. I've taken a close look at the motherboard, I couldn't see any burn marks or anything out of the ordinary. I also have tried just the motherboard hooked up to the display and AC adapter, and still no luck.
