Re: Trouble Locating Shorted Component

Thanks for the reply, RJ. So a resistance of less than 2 ohms would be normal on a power rail that carries low voltage?

I'd considered the fact that it might not be shorted, but after measuring a bunch of other points on the board, I couldn't find any resistances lower than 50 ohms or so. That's why I thought the 1.4 ohms or so might be a short.

Hi everyone,

I've been trying to revive my 2015 Dell XPS 13 (9343). So far I've been able to locate a short to ground on the 1.35v power rail on the system side.

After doing a bit of research online I came across Louis Rossman's videos on finding short circuits where he applied an expected voltage to the power rail and then feels around the board to see which component gets hot.

Unfortunately, the board only takes around 0.8 amps at 1.35 volts. Ultimately, 1.35 volts at 0.8 amps isn't enough to make the component hot, and I'm hesitant to crank it...

Hi all,

My name is Coleman, and I'm currently and engineering student at the University of Alabama. I've always been interested in computers and technology in general, and after taking an interest in Louis Rossman's videos on Youtube, I've been inspired to try and revive a broken laptop of mine.

I'm just here to learn what you guys have to offer. Thanks in advance for your help!
