Using a different AC adapter than the original - yea or nay?

post #1 of 6
Thread Starter 
Alright, sitting here in Port-au-Prince and can't get back to my base in Leogane because some gang violence shut down the national highway. Haiti has a way of keeping things interesting.

Anyway, don't know how long I'll be stuck and I need to work so I need to charge my laptop. I brought it with me but didn't bring the charger thinking this would be a one day trip. So, my question:

Is it OK to use a Dell AC adapter to charge my HP DM1z? The DM1z, from what I can tell, uses a 65W adapter with 18.5 volts. The Dell adapter is 90W with 19.5 volts and 4.62A. From what I've read, the watts don't matter unless the computer is not getting enough of them, which in this case it isn't the problem. However, given the Dell adapter is one volt higher, am I going to fry my battery / computer? I've read modern computers can handle voltage variance, but want to be sure. To be clear, I don't expect to be stuck here for more than a day or two so it would likely only be for a charge or two. Still, want to be sure as getting a replacement laptop in Haiti is a pain in the ass.

Mesi,

Well, you are correct in that itll only pull as much watts as needed. If youre worried about it, try it, and if the battery heats up (within a couple mins) then dont use it. You may still be able to use the adapter with OUT the battery in and use it to just power the laptop. I dont think an extra volt will matter, but to be sure, be careful.

Your voltage is close enough that it should be okay as long as the polarity is correct. But as stated earlier keep an eye on your battery's temperature just in case.

the amperage is something to worry about,if its higher hope you dont fry your laptop..
Frying your battery is the least worrisome scenario.

Wattage and amperage are ok if they are higher at the same voltage. Once again as stated they will only draw what the need. Going lower, you run the risk of cooking the device. I would probably not do it regularly. Might be ok one time to get what you need do
