optiplex gx150 how to save bios settings

The smaller of the two panels reveals the system's 2.5-inch hard drive and a lock switch for the DVD/CD-RW combo drive, which pops out (or not, if you lock it) just like that of a notebook drive. As you might expect, there's no room inside for slots of any kind, save for a pair of SDRAM slots, both of which are occupied. The tower has two access panels, either of which pops right off with the push of a small, green lock switch. The cleverly designed case can be hidden behind the flat-panel display. Despite its intended corporate audience, the near-$2,000 OptiPlex SX270 would make an excellent home-office system, as well. Factor in Dell's industry-leading warranty, and the OptiPlex SX270 rivals IBM's ThinkCentre S50 as the business PC to beat. Plus, what the SX270 lacks in internal expansion, it more than makes up for with its endless supply of USB ports. Its 2.4GHz Pentium 4 processor, Intel 865G chipset, and 512MB of DDR memory make it impressively fast for a business system, and its clever design saves space and upgrade hassles. What else can be done to solve this problem.Who says corporate PCs have to be dull? Witness the Dell OptiPlex SX270, a tiny tower built for big business.

It is the removal and replacement of capacitors is what I have not done as there is no bulging capacitor on the mobo. I have read similar posts on the same type of Dell desktop and follow the steps or suggestions which have not yielded the expected result.

Once the power cable is removed from the psu even for as short as 5 seconds, settings are lost whenever I restart the system.

The system will boot into windows without any error message as long as the power cable remains in the psu. I remove the Pswd jumper for the RTC reset pin, restart the system, reset time, date and others save the settings and reboot the system. Some of the discovery I made include a dead power indicator lamp, but the system still boot, and none existing jumper on RTC reset pin. I have changed the cmos battery from another desktop Optiplex GX 745 that works yet the problem remains. I have a 2nd hand bought Dell GX620 desktop which failed to remember it's bios settings once the power cable is removed from the psu or there is power cut from the public power supply.
