Introduction The development of ultra-low power LSIs is a promising area of research in microelectronics. Changed CMOS battery on a Dell Optiplex now PC won't power up at all I've got a Dell Optiplex SX280 that was reporting system voltage low on the CMOS battery. PS (leakage current) (supply voltage) Most CMOS data sheets specify an I CC maximum in the 10-µA to 40-µA range, encompassing total leakage current and other. IC Switching Levels, Chart of voltage thresholds for TTL,CMOS, LVCMOS, GTL, BTL, ETL, and BiCMOS devices, showing input and output switching levels. CMOS Checksum Error; CMOS Battery Failure; System battery voltage is low; If any of the above issues or messages are encountered, you likely need to replace the CMOS battery. I Think, despite my tested voltages appearing okay it MUST be the PSU that has failed. Note that CMOS logic gates and devices are static sensitive,. CMOS Battery minimum voltage - forum-en. I'll order one next week, but I don't really know how to fit it in the special casing. 0 volt internal battery soldered to the PCB that powers the clock chip.
