Resolution of 800x600 with 16-bit colors (65536 colors).
B. USB Hubs and Extension Cables 
Self-powered USB Hubs: An external USB hub expands a single 
port to 4 or 7 ports. If the hub gets its power directly from 
the PC through the USB cable, it is said to be "bus-powered".
If the power is supplied externally, in other words if it has
its own power cord to plug into an outlet, the hub is 
considered "self-powered". 

If the hub is self-powered, the external power cord must be 
plugged into a battery backup outlet on the UPS. Configured 
in this manner, the UPS will be able to sustain power to the 
hub during an outage. Failure to do so will result in a loss 
of power to the USB hub which will inhibit the operation of 
all downstream peripherals. 

C. USB Extension Cables: 
USB was designed to operate in the local desktop environment. 
Full speed USB devices can be connected up to 5 meters 
(~16.5 feet) apart. Low speed USB devices can be connected up 
to 3 meters (~10 feet) apart. The APC USB UPSs are low speed 
peripherals and should be connected directly to the PC or hub 
to ensure reliable operation of the PowerChute Personal Edition 
software. The USB Standards Committee and APC do not approve
the usage of extended USB cables. Their usage will not harm 
USB equipment but overall system reliability could be affected.

D. Online Help:
The context-sensitive help (which is displayed when you
press the information button or F1 on the main application) 
displays a page with the title 'The page cannot be displayed' 
when the software is installed to a long path (i.e. greater 
than 56 characters) on your system. This is due to a problem
with the help facility being used. To avail of help, install
to a path that is shorter than 56 characters.

E. Keyboard Access:
It is not possible to navigate through the application using 
the tab keys. Use your mouse to navigate around the 

F. Netscape Issues:
For computers that have Netscape configured as the default 
browser, you may get a dialog indicating that Windows cannot
locate a web link when you visit a page through the 
You may launch Netscape and type the web address manually or 
use Microsoft Internet Explorer as your default browser.

G. Multiple Setup Execution Issues:
Problems may arise if you try to run the installer twice in 
quick succession. When you launch the installer, wait until 
it is finished before trying to run it again.

H. Error Messages from USB Devices:
Ensure that all USB devices connected to your computer via the 
USB port are powered up before booting up your computer. This 
will prevent driver error messages from appearing and reduce 
compatibility issues between devices.

I. Creative Labs SoundBlaster Live!Value Issues:
If you have a Live!Value card installed on your system and you 
experience a crash in DEVLDR16.EXE when the system is shutting 
down, disable SB16 emulation on your computer. See for more details.

J. Upgrade from Windows 98/Me to Windows 2000:
If you have a previous version of PowerChute Personal Edition 
installed on Windows 98/Me and you upgrade to Windows 2000, 
you should uninstall the software as it is not currently 
supported on these platforms. Note that after uninstalling the 
software, the shortcut on the desktop and the Start menu remain. 
You should delete these manually by right-clicking on the icons 
and selecting 'Delete' from the menu. Registry entries may also 
remain after uninstall, but these will not effect your system
in any way.

K. Compatibility with ZipMagic:
You may experience problems with your computer if you have 
ZipMagic running when PowerChute commences a shutdown. If this 
occurs, it is recommended that you close ZipMagic when you are 
going to leave your computer unattended for a period of time.

L. Troubleshooting Lost Communications with your Battery Backup:
If your PowerChute software has lost communications with the 
battery backup and you have carried out all of the steps 
outlined in the troubleshooting section of the online help, open
the Device Manager from the system applet in the control panel 
and press the 'Refresh' button to update the device list. The 
battery backup should now appear in the device list.

M. Files Locked During Uninstall
If you are presented with a dialog indicating that files are 
read-only or locked while uninstalling the software, close all
components and files associated with the application such as 
the release notes, the main application, etc. Then press 'Yes' 
or 'Retry' to proceed with the uninstallation. Otherwise, files
may get left behind.

N. Swapping USB battery backups on Windows XP
If you have PowerChute Personal Edition installed and you 
connect a battery backup to your PC that was not connected to 
your computer before, you should reboot the PC to avoid 
Windows native power management from being re-enabled. If 
Windows asks you to reboot as soon as the battery backup is 
recognized, you should reboot twice. Rebooting is not required
after that.

O. Upgrading from Windows 98/Me to XP
In order for Windows native power management to be completely 
disabled following an upgrade from Windows 98 or Millennium 
Edition, you should reboot your computer.

P. Time to turn on your computer following a power outage 
When your computer shuts down or hibernates, it causes your 
battery backup to go into sleep mode some moments later. Even
if AC utility power is restored before it goes into sleep 
mode, do not turn on your computer until all lights on the 
front panel are turned off. Otherwise, the battery backup 
will stop supplying power to your computer for a moment, 
which could cause problems for your system if it is booting 

Q. Acceptance of the APC Battery BackUP driver on Windows XP
On some systems, during the install you may be asked if you 
want to accept the driver 'APC Battery BackUP' as Windows 
indicates that it is not signed. This message should not be
presented as this driver is signed and approved by Microsoft, 
and is safe to use. Press the 'Continue Anyway' button to 
accept the driver.
