Here's how one accesses the Threshold settings:
Plug the Back-UPS into power, but don't turn it on. It should be in standby dell laptop battery mode with no LEDs lit.
Press and hold Master/Enable for ten seconds. All the LEDs will then flash to indicate that it has entered programming mode.
Release Master/Enable. The LEDs will then indicate which threshold setting is being used.
Press Master/Enable to select a different threshold setting.
And the LED indications are:
Low (10 Watts) Master/Enable LED flashing.
Medium (25 Watts) Master/Enable and Online LED flashing. (This is the default.)
High (60 Watts) Master/Enable, Online, and Replace Battery LEDs flashing.
Hopefully you won’t need to alter these Laptop Battery settings, but if you do, there it is.
Results of Testing
Out of the box, the APC worked fine with the multimedia PC. We had to change the threshold settings in order to work with the laptop. Performance was spotty when the UPB-90 external battery was in line between the laptop and the APC, but removing it and resetting the threshold back to 25 Watts solved the problem with the additional drive in the laptop. The unit then correctly identified both hibernation and hybrid sleep (in Windows Vista) and worked with a satisfying CLUNK when it switched the controlled outlets off.
And, as a note, in normal operation, one does not need to get under one's desk to switch the unit on before starting the computer. Simply pressing Start on the PC causes the dell Inspiron 5100 battery APC to also apply power to the controlled outlets. It's very convenient in use.
Using the Software
Here are some of the PowerChute screens. "Runtime Configuration" is where you can adjust it to run your computer as long as battery possible, or shut down after some specified time when running on backup power. The "Performance Panel" shows events like power outages, under and over voltages, and line noise that happened in the past. The "Self-Test" screen checks on the operation of the device and the condition of the battery. It also has a link to order a new battery or to inform APC that you've installed a new one.
The "Notification Configuration" screen allows you to dell 6T473 battery specify the times that the device should remain silent, even in the event of a power interruption. This is handy if you live in a place that frequently has power fluctuations when you’re trying to sleep.
There are also user-selectable settings for sensitivity to line noise and voltage fluctuations.
Fit, Finish, and Design Rating
As Bright Hub reviewers have come to expect from APC, the fit, finish, and design battery of the ES 750G are excellent. It has long, full-length, functional vents on the sides. Four of the outlets are widely spaced for angle and overhanging end plugs, which seem to be becoming common (and commonly annoying) with cell phones and other small devices. Connections for DSL/phone/cable, the reset switch, and the power fault LED are all conveniently grouped on one end along with the main power cable. The other end is unadorned and elegant in its simplicity, and the LEDs are dell Inspiron 630m battery bright.
Dimensions
The unit weighs 10.36 lbs (4.7 kg) and is 3.5" high, 13.5" long, and 7.1" deep (88.3 x 342.7 x 180 mm).
Warranty
The unit is warranted for three years from the date of purchase. The customer should contact APC Tech Support for an RMA (return materials authorization) and should pay shipping to APC. APC will pay for ground shipment back, and the common practice is to replace the device with a remanufactured unit.
Conclusion
So there you have it - the Bright Hub dell Inspiron 640m battery review of the APC Back-UPS® ES 750G backup power supply. Should you consider spending $99.99 for this unit? Yes, if you have a need for a backup power supply and want to be eco-friendly while saving a little on your electrical bill, it's an excellent choice. It's a set it and forget it device that you won't normally have to spend much time thinking about. When needed, however, it will continue to run your PC and accessories for the time you've specified and even shut down your PC and controlled components when completely unattended.
We also found that it works as well with laptops as it does with desktop computers and that having three controlled outlets is enough for the peripheral components that need to dell Y9943 battery be powered during blackouts and brownouts.
Bright Hub gives the APC ES 750G an overall excellent rating and it carries our best battery recommendation. It is a product that works as advertised.
