TimeKeeper RAM failure


Greetings, If you have a TimeKeeper RAM failure you will see the monitor show no progress after the second bar of the boot-up process. It may also indicate a BBRAM failure. If this is the problem you are seeing then the following is the solution.


You will need to replace the Timekeeper RAM IC that is located on the CPU. Some units use a RAM IC with a separate battery, most use a RAM with a built in battery. These IC’s are physically taller than a standard memory IC. Usually the TimeKeeper is a Dallas semiconductor IC. It is a socketed IC and is very easily changed. If you remove this IC the system ID and date will have to be reset even if the IC is still good. There is a lithium battery that provides the RAM backup. With age this battery will fail and the system ID and date will be lost. That is indicated by the program not booting past the second bar on the monitor. You can select whatever numbers you would like for the System ID. I recommend that you use the serial number. This will make it easier for anyone else to work on the system. It will also allow you future servicing should you lose the number.


I have attached 5 files. Connecting the Logiq 400 to a laptop computer.doc and Venus Logiq 400 ID time reset without GE contacts.doc are the ones that outline the actual procedure. The Logiq 400 resetting password.doc and Logiq 400 System ID change.doc are for general interest. GE Links.doc provides a link through GE to obtain the service manual if you don't already have it. You will need a PC or laptop running a terminal program. We use HyperTerminal. The older versions of HyperTerminal will not work on Windows 7 or 8. You will require a new release to use these operating systems. The serial cable required is a straight through serial cable. Usually 9 pins on the computer and 25pins on the Logiq. Pin 2 connects to 2 and pin 3 connects to 3. The service manual gives the details regarding the cable and the setup.

HDD reformat

I have a new HDD for a Logiq 400 destined for a unit in Afghanistan. We are attempting to copy the known good software from a HDD to another to send it along. We are not able to read the format of the working HDD to allow us to clone or copy. It is not EXT3, FAT or NTFS. Any ideas? Your help is greatly appreciated. Ron.
