I have a Dell optiplex GX260 machine that i am planning on using as a MAME arcade system but I'm having a CMOS battery problem. The problem is that when i boot the machine up it displays 'Alert! system battery voltage is low' so I got a new coin cell battery to replace the old one but i still had the problem of the message. Then I reset the time and date in the BIOS which had appeared to fix the problem. Then i went on holiday for a week and when i came back the warning was there again. I tested the battery with a power meter and it read 3.12 volts so i knew there was nothing wrong with the battery. Please can you help me.
