Well, you said you replaced a RAM. Your machine has two slots. Are both the modules the same ones that came with the machine? One should be labeled DIMM A and the other DIMM B. The manual has a cautionary statement about installing DIMM A first. Some machines don't like it if you don't fill all the slots up starting with the lowest numbered slot. And If you had a bad RAM module, that could be the case. So, its possible one or the other is bad. Also, is it possible you installed a mismatched module?

Compare to this (apart from size).

If you can't enter CMOS (Configurable BIOS) still, then I'd still be suspecting the RAM.

After replacing the battery, the BIOS checksum error would have appeared due to CMOS having been cleared by the battery being removed. It should automatically reload the defaults. You could force it to do that again, by removing the battery. Once you can get into CMOS, there would be an option to select factory defaults and possibly other saved configurations. I haven't ever noticed that option, but then there are many different BIOS out there.

Your new CMOS battery may already be less than 3 volts if it's been in storage a long time in a warehouse or shop. Even 2.8 volts is too low.

Buy another one from a different supplier.

Hi Changed New Battery now i got another problem running on every time when i boot up.!!

ON BIOS SCREEN - ERROR 1 : 0271 : CHECK DATE & TIME SETTINGS

WARNING 1 : 0251: SYSTEM CMOS CHECKSUM BAD - DEFAULT CONFIGURATION USED.

Then Finally Press F1 to Resume & F2 to Setup.

The problem i cant understand even when i changed my date & time and after shutdown and reboot. I'm getting the same error message and beep sound. But this time it is started showing bios screen previously nothing.

Any suggestion please.??

Dell Studio 1558 right?

Did you replace the battery with the same number? You could try measuring it with voltmeter in circuit?

Five beeps indicates Real Time Clock failure (see setup manual).

Does it keep time when its set and running.

Dust maybe causing you problems. Dust can be conductive and cause unpredictable behavior. Blow it out with compressed air. Use a compressor that doesn't spray out oil or water with the air.

In the BIOS, select one of the preset configurations so that the complete configuration is written to the CMOS memory. This should fix the checksum error. Then set the date& time.

If that doesn't work check if the battery is properly seated in the battery socket with good contact (tension).

Did you try booting with just DIMM A installed?
