Pry it apart along the edge with an exacto. Be careful around the antenna where it is circular.

Get a new battery to match and a battery holder from DigiKey.
Solder wires to the new battery holder and secure it at an angle up by the antenna with white silicone making sure that the case closes. Get the + and - right when you solder.

Test the unit then secure the case with white silicone in a small bead.

Where is the CMOS battery located?


On most desktops, it will be located on the motherboard, sitting in a slot socket. These batteries look like nickels and sit in the socket with their positive side up. They are usually held in place by a tension spring.

If you have a laptop, then the battery maybe accessible through an access door on the bottom of the case. These batteries can also be a disc type battery sitting in a slot or it can have a special covering with a small cable attached to it, this small plug attaches into a socket. In some cases, the laptop has to be disassembled in order to remove or observe the battery.

Battery to change as do not keep the time date.


Hi:
Your compaq mini tower has a coin type battery that is mounted to the motherboard that keeps the time and date. It usually is a cr2032 , but you need to take the side cover off of your tower, with the tower unplugged, and locate the battery. take note of how it is installed. It is a 3 volt lithium battery that you can buy at most stores for about $2-3 and is easy to swap out.
Give it a try, and your computer will remember after you reset everything!

The doorbell buttons and your receiver must be on the same channel. If you will get out the directions that came with your unit, they will describe the process to go through to reset the specific "codes" for your buttons and receiver.

Need help diagnosing dead UPS


Very likely, "would this also explain why none of the indicator leds are working?"...the dead batteries are your problem. you can try this test, since you had it opened: 1.) disconnect internal batteries, label the wires by terminal location. 2.) connect (2) 12 volt car batteries to same exact wires that you just disconnected, noting correct polarity. 3.) power up UPS. if everything ok, then buy 2 replacement batteries for UPS. if not ok, buy new UPS after through search inside UPS reveals no blown fuses or other faults including poor wire connections.

"Upload ...Not Present" message. Nothing else on the screen. I replaced the internal battery last spring used it all summer. Have just checked internal and external batteries and all are fresh 3v internal and new AA four batteries. Upon startup the screen says "Upload" "Not Present" and there is no menu. I have tried hitting Page and Menu, etc. nothing happens. I tried leaving it out and on for 3 hours to see if it would find itself and satellites. I tried connecting to the computer and uploading the internal program the port was not found. Tried this a number of times and a number of ways. I have tried leaving it on to search for 3 hours and have tried to connect to my computer to reinstall the software but that does not work. The internal battery was replaced with a new one last year. I have fresh batteries in the unit. What is the problem? How do I fix it? Thank you. I love this unit and would like to keep it going. I have fixed two others for friends who needed the internal battery fixed. They use it as a backup. I have tried the Auto Locate procedure about 3 times. I have also tried clearing by holding the PAGE + Power. Then tried autolocate. Message "Upload... Not Present" still remains. Also have tried clearing by holding the MARK + Power. Then tried autolocate. Message "Upload... Not Present" still remains. Now I am wondering if this message has to do with an interrupted connection with EasyGPS from last winter. I was uploading waypoints, and thought it had completed and may have turned off and disconnected the plug before an operation was completed in saving waypoints off the Garmin 48. I do not know this for a fact, but that was the last operation I recall doing last fall, before starting the GPS up again on the boat this spring. I have also tried to connect the unit to Easy GPS via the serial port, thinking perhaps it would complete whatever it is trying to do. I have tried uploading routes and downloading routes via EasyGPS send and recieve and it does not seem to work. I wonder now if the interface setting has been reset, by my pressing PAGE+power and Mark + Power earlier. I would not mind that if the menus came up properly, but that is not happening. Is there some other way to kick it out of this mode? I turn it on and there is the message "Upload...Not present" and none of the menu buttons work to get it into the normal startup screen mode..... I've tried Quit, Page, Enter, Goto, Mark, Power (off and on), and none of the get the computer out of this mode and back into the normal menus for startup. I've removed the antennae and checked all the contacts and that seems fine, and reinstalled. Is there some small reboot button inside that I can jumper? I have tried taking the internal battery out and letting it sit for three days and it still does the same thing. Any suggestions would be appreciated
