[Jane]

Are there general guidelines that tell what resistance each voltage rail in laptop should have?

Meters vary in features, cost and how rugged they are. Recently purchased a Fluke 87V/E2 from a local reseller at a nice discount. Too expensive to buy at full retail price.

You may want to read the articles on EEVBLOG about this topic:

EEVblog Brymen BM235 Multimeter is what they recommend.

There are many on Aliexpress at varying prices.

I don't think there is any need for a great expense, you need to measure voltage and resistance and diode mode is useful.
Save your money for other tools.
