Sony PCV 90

[azteca36]

I have a sony PCV 90 computer (very old). I'm having problems with the time on the computer. When the computer boots up, it's telling me that the CMOS time has to be reset. I replaced the CMOS battery but it's still giving me the same problems. I have four other computers in my house so getting a new computer is not an issue. I just want to get this one to work right. I've had it forever and I don't want to let it go. Any ideas?:D

Here is an article on that (http://www.geocities.com/micksmix2000/cmosbatt.html)

Thanks for the info. After I installed the new battery, I tried resetting the CMOS but it still does the same thing. When I reboot, it keeps telling me that the time is not set. Could there be something else wrong with my motherboard?:hmm:

hi
VERY old computers may have a problem.. That was once described as the millenium bug.

strange that this would show its ugly head after a battery got changed, but it is (I think) possible.

Is the time correct or has it been reset?

Third-party utilities or programs and/or screen savers can cause the time to stop or decrease significantly. If you are running Windows 95, Windows 98, Windows ME, Windows NT or Windows 2000, close all screen savers and attempt to end task all TSRs and disable all screen savers to ensure your lost time is not being caused by this issue. Information about how to End Task all TSRs can be found on CHTSR (http://www.computerhope.com/issues/chtsr.htm)

If this does resolve your issue, reboot the computer and attempt to determine which TSR or screen saver was causing this issue. Once the culprit has been located, see if the program has any available updates to resolve your issue.

Issue with APM.

APM, or Advanced Power Management, can cause issues with the computer keeping time. Verify this is not the issue by entering CMOS setup and disabling APM or Power Management.

If this does resolve your issue consult with the motherboard manufacturer or computer manufacturer for a possible BIOS update.

Computer CMOS battery failing or bad

The date and time will commonly get reset to the BIOS manufacturer date, or a default date such as a 1970's / 1980's date. When this occurs, this is generally a good indication that the CMOS battery is failing or is already bad.

Before replacing the battery, attempt to set the date and time to the correct values in CMOS setup and save and exit the setup.

If, after saving the values, the date and time are reset when turning your computer off and on, attempt to set the values again but this time leave your computer on for 2-3 days without turning it off. In some cases this can help enable the CMOS battery to retain its settings for longer.

If this doesn't resolve your issue you will need to replace your CMOS battery. (Well you've already done that and surly you didn't buy a bad battery)

BIOS NOT Y2K COMPATIBLE

It is possible that older computers may not have a BIOS that is compatible with any year 2000 dates. If your computer was manufactured before 1995 it is recommended that you contact the manufacturer of the computer or motherboard manufacturer to determine if the computer motherboard / BIOS is Y2K compatible.
