A further consideration involves whether the device is essential to the operation of the computer. Printers and scanners are not, so you wouldn't want them running when on backup battery power. (But you sure would want that monitor.)
Four other outlets are both surge-protected dell laptop battery and backed up, and these are located on the same row as the master outlet.
The two right-most outlets in the second row are surge-protected only. They are not backed up, and they will not provide power to battery accessories during a main power failure. These would be logical for a scanner or a printer. (If you need to use a printer or scanner during a power outage, you might need a backup generator.)
Software Installation Rating
The Back-UPS ES 750G comes with the venerable and respected PowerChute® Personal Edition version 2.0 power management program. It's compatible with Windows 2000, XP, and Vista. Version 1.5 for Windows 98 and ME are also included on the CD, as is version 1.33 for Mac OS X 10.3.x and 10.4.x.
The unit should be plugged in to the wall socket and have the USB cable from the power supply connected to the computer. The installation will abort if a supported APC backup power dell 6Y270 battery supply is not found.
The installation is pretty standard. The second step involves agreeing to the terms of service, and battery then it offers a default install location.
The installer provides the option of registering the device online in the final step. The model number and serial number for the device can be found on the outside of the box. There's also a printed, triple-fold registration sheet in the box that you can fill out and mail in. APC seems to be very interested in where, how, and with what equipment the Back UPS will be used.
An icon is then placed in the notification area (system tray). Right-clicking and selecting "Open Application" shows the main program dialog.
And here's what it looks like at dell 1X793 battery first run.
Operation and Use Rating
We tested the unit in several different configurations. One was with a multimedia desktop with one external hard drive, one external CD/DVD drive, a sound system, and LCD monitor. Another setup was a laptop with no external accessories. We also tried the laptop with an external CRT monitor. Finally, we tried the laptop with an APC UPB-90 universal battery extender plugged in between the laptop and the Back-UPS.
Using default settings, the device worked like a charm with the desktop PC. We tested with the external hard drive, monitor, and external CD/DVD drive plugged into the controlled outlets. The sound system was plugged into a surge/backup outlet, and we added two "power bricks" for cell phones in the surge only outlets. Shutting down Windows from the Start-Shut Down menu caused the Back-UPS to quickly shut down the accessories as well.
Results with the laptop were interesting. Between the start of testing and finishing, I had installed a new battery hard drive in the laptop and moved the existing hard drive to a caddy in the dell C1295 battery CD/DVD drive bay. After doing this, I was surprised to find that the Back-UPS failed to detect when the laptop was hibernated. I confirmed this by removing the hard drive and reinstalling the CD/DVD drive, and the Back-UPS worked normally. This called for some head scratching, as the "Master Enable" LED was lit, indicating the system remained active. The answer, of course, was in the User's Guide, and we'll include this in the review as it will be good information for laptop users.
If you are using the ES 750G with a laptop plugged into the Master (main) outlet and the APC fails to recognize when the laptop is hibernated or put to sleep, refer to the "Threshold Programming" section in the User's Guide. You could also conceivably have the opposite problem. A really low power device like a netbook could make the dell Inspiron 1100 battery Back-UPS think that it should shut off the controlled outlets even though the PC is still running.
