Yes, to the left there's a kaby lake platform with Intelยฎ Coreโข i7-7500U CPU and Intelยฎ HD Graphics 620 GPU. Should I rather use resistance mode (than continuity testing) to test these? There are some inductors on the other other side of the motherboard that can't test (no beep & infinity measurement).... -
Oh I thought I learnt something ๐ unfortunately I don't have the boardview file only schematic. And there's very little writing on the board itself - i.e. not many things are labeled like I've seen on other motherboards that people use to teach on (e.g. on educational YouTube vidoes), so it's difficult no know what's where.
When I touch my meter probes, it reads 0.1ohms. it's a cheap meter though, unlike fluke, so it might not be accurate I guess.:/Leave a comment:

Beginner question. Did I find a short?? HP dax31mb1aa0 REV A motherboard
Hi beginner here, so I'm not sure of I've done this right ๐ trying to diagnose my laptop's motherboard (dax31mb1aa0 rev a). I don't quite know how to read the schematic, so I'm attaching the pictures of the motherboard and the measurements.
I was attempting to measure resistance to GND on inductors. I disconnected motherboard and used "continuity testing" setting on my multimeter. I put black probe to Ground & red probe on an inductor. Did I measure this right? Am I correct to think that 0.3 ohm measurement indicates a short circuit? Thank you for your help!... -
Thank you so much for your reply!! Yes, but I'm willing to learn! It's quite interesting the more I look into it. The difficult thing is that there's so much info and a lot of it contradictory/misleading. It's hard to know where to start and what's correct.
Aah you'll need to dumb it down further for me I'm afraid ๐
what multimeter settings should I use (I saw some videos where diode&continuity test setting was used for it, on my multimeter- these are separate separate)? Also, double checking, I'd need to use input on the right side, correct?
Sorry...Leave a comment:

Motherboard diagnostic beginner advice
To save you some time: the most important bits are in bold.Some further examples/explanations or to the side & in grey - you can probs skip them if it's TLDR for you. Sorry, I've got ADHD & tend to over-explain stuff - just like I'm doing right now ๐ Briefness is for poets not me ๐
Please help!! ๐ถI'm just a girl in a world that wants to scam me out of lots of money for any tech stuff/repairs ๐ต Seriously tho, I'm poor&I can't afford to get laptop diagnosis, especially if it ends up needing a new motherboard.
Where I live, all the tech shops are run by very...
