Is it a bad idea to connect an Acer Laptops? power cord to UPS Backup?

All right, I?ll place this question here seeing I have some heavy knowledge available here.

I read this on my old Compaq book, ?Don?t use an UPS battery back up for power.?

Okay, UPS has a battery fed by Utility fed AC to a battery & DC/AC Generator, and so forth.
It is almost the same with the Acer Laptop power cord to its? internal battery.

I don?t see anything in the Acer documents that warn of this type of hookup. I think I may be okay in hooking this configuration up, what say you?

A typical notebook a/c adapter is going to draw between 65-100 watts. It's not a problem to connect them to a UPS.

Thank you John. I feel I can too. There must have been something in that old Compaq that conflicted with Ups Backup devices.

maybe it was that when the ups were built at the time of your laptop, they weren't up to snuff.

i would hook a laptop up to a ups in a hearbeat, although i don't think you need it because if you are on a/c, and the power goes out, the laptop will switch to its own batter, just like you unplugged it.

what you do not want to plug into backups are printers...

I concur. However it's laser printers that are taboo.

I plug my Toshiba notebook and USB hub to a light-duty 350VA APC UPS. So far no problems.

i had read somewhere (cant remember) that even inkjest tooks some juice, although i don't know how. but a laser, with its fuser getting to ~400F definately takes some juice

Inkjets are usually fine, its just a tiny motor...

Good information on Printers! Thank you all, however my thinking was to have a hell of a buffer between Florida Power & Light and their power problems of high voltage and brownouts hitting my computers. I was also looking for a quick easy extra battery time on my laptop when I lost power.

I lost most of my main and backup computers the last two years in the Hurricanes and just now built my first desktop and bought a laptop. I learned a lot in my build, but I lost one good computer. I partially restored that one where I can use it, but now I don?t need it that much. I always back up my files to a CD.

All but the most expensive UPS power supplies produce an "emulated" sine wave. It's a stepped square wave that can cause problems with certain kinds of power supplies. In practice, it's a seldom-seen problem. But, theoretically, it's possible to damage some kinds of electronics with that kind of wave.

that is what i had thought, glad that was clarified because i couln't fathom how a inkjet could use much power
