Laptop Power

How fussy are laptops?
I have a Gateway MX6124 Notebook PC that has a 19v 3.42A power supply.
Can I run it from a power supply that puts out 19.55v 3.65A ?

 

I don't think so tim, you will be over volting. shorter component life, and general badness may insue. I wouldn't do it, especially since you can buy the right adapter for like $20.00 on ebay, and sell back your high voltage one to who ever has the laptop that goes with the adapter you have for about the same money.

 

Yeah you shouldn't use an adaptor with a different power different rating for any electronic device than the one required. The electronic components within them require very precise voltages and currents to function properly.

Power = current x Voltage

19 x 3.42 = 64.98 watts
19.55 x 3.65 = 71.3575 watts

thats a difference of about 6 watts between the adaptors - using that power supply could cause instant irreversable damage to your laptop! (unless the laptop's PSU has an inbuilt fuse, which I don't think it does)

so to answer your question, no, and hope I didn't put you to sleep
