From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I would say, just check if voltage and and current are the same as your previous charger. If they are, you are OK. If they are lesser than before, you'll charge slower. If they're above, you're gonna harm your battery.
I was taught that it's really only voltage that really needs to match to avoid damage. And even that can be a bit fuzzy with modern electronics and their charging circuitry.
The wattage and amperage only measures how fast the charger will recharge the battery. There will be a minimum amperage needed to power the laptop... but as long as you exceed the the minimum the laptop will run fine even if the adapter is capable of crazy high Amps. The laptop will only pull what is needed.
U = R x I
volts (U, probably 19VDC) is constant. The laptop has a resistance (R). This means that the laptop has already dictated the amount of currents (I) that it pulls. You can connect an 100A charger to an phone. The phone dictates howmuch it actually pulling. There is no battery damage/harm in doing so.
If you charge a battery at full-speed, It can heat up. This is in the long term bad for (Lithium) batteries. That's where the myth might come from?
*fixed formula order
All correct but R=U/I
Its the same equation
