Will this charger/adapter work with my laptop?

That only happens if you're using some cheap, junk adapter. A proper, certified one—like the OEM stuff you get from Dell or HP—has built-in overcurrent protection. It won't blow itself up; it'll just provide the maximum current allowed by its specs.
It's the same deal with phone chargers. You can plug a modern smartphone into an old 5W brick, even if that phone is capable of pulling 3A at 5V (which is basically standard nowadays for 15W charging).
