My friend has a laptop with no power cord and I have a power cord with no laptop. The hp power supply happens to fit the compaq laptop(i wonder why).
I'm not 100% on the values as I don't have it with me at the moment, but the laptop requires about 18.8v@3.5amps and the PSU cord is about 19v@4.3amps. Basically, they're different values and the laptops are both lower.
Will this fry if i plugged it in, or will the laptop only draw the power it needs?
