Computer Gateway2000 486DX2 60 MHz PhoenixBios

When I start the computer I have on the screen:

Gateway2000
CPU ??? ???Hz
System RAM Passed 00640K
Extended RAM Passed 0015360K

Press <F2> to enter SETUP

Cache SRAM passed 0012K
System Bios shadowed
Video Bios shadowed

System battery is dead - Replace and run SETUP
Real time clock error

When I press F2 it says entering setup and reestarts again. BATTERY is new, I changed twice already. What to do to access the Bios? I cleanthe battery socket with a brush and check every pin entrance, the battery looks like a microchip.

To access the Bios setup,locate the designated key in lower left corner,press key when start up screen appears (Delete may be designated key)

You may have lost the configuration settings if the battery was inoperable for a long period of time,use the motherboard manual to reset dthe configuration

To access setup in this computer you press F2, but I can not access because when I press F2 it says Entering setup... and instead it reestarts again. I can not access the Bios.

Wow,

You say the battery looks like an IC?

I have seen a few PCs where the battery was built into the Real Time Clock / CMOS memory chip.

If this is the case with your system, make sure that none of the pins on the IC are folded under, or outside of the socket.

Then, because the chips are likely more than 5 years old, you will need to let them charge up for several hours before they will start working. (this assumes a nicad batery, if the chip uses a lithium battery, the battery maybe dead when you get the IC!)
Try letting the PC run for 3-5 hours at the BIOS prompt.
Re-boot, and see if you can enter BIOS settings.

Keep in mind, if the battery is built into the RTC, it may have been running since the IC was fabricated. In this situation, the battery will go dead just sitting on the shelf.

Unless you have some special situation that you need this PC for, I would go out and get a newer used PC. I have seen PII's for under $100.

The computer uses a lithium battery, and this battery looks like a microchip, only bigger. If would like to see it go to www.eBatts.com and look for cmos battery, B-280 - Lithium Battery, I need to have this computer working, a good friend asked me to upgrade for him and when I finished installing the sound card this happened, everything was working wonderful, suddenly....your answer did not help me but you seem to be getting there. Thank you.

So, I did guess correctly, that it is a battery and clock module.

Have you tried going through the reset CMOS memory procedure for this PC?
Without a full model number, I cannot look it up on Gateway's site.
I assume that there is a jumper on the motherboard that needs to be set, then boot up, shut down, and place the jumper back to normal.

Beyond re-setting the CMOS, is there any way to verify if the battery is good?

If this module is designed to not drain the battery during storage, is there some procedure that you need to go through to activate the battery?

One more thought, are the part numbers on the top of the new module the same as the old module?
If not, I would see if you can get a data sheet from the module mfg. There might be a difference in the pinout, or some jumpering that is required to activate the battery.

Here is a link to a Dallas Semiconductor (Maxim) tech note on replacing RTC modules.

Remove any spaces from the pasted link.

From a link in the tech note,
http://www.resource800.com/dalfaq.html

They state that for some systems, you need to run the manufactures setup disk the first time you boot after replacing the module.

I would deffinately attempt to find whatever info or downloads that you can from Gateway.
Their procedure / program may be your only hope.

I checked the websites you suggested me and I found something strange, the battery I bought came marked 3.0 Volts while the one in the www.maxim-ic.com is marked 5.0 Volts, both of them have the same number. I used the technical informationI found to check the battery volts, with a multitester, I did not get anything. I am going to contact them for more information on the phone. If it solve my problem I will be pleased to let you know. Thank you,
John

Hi John,

Just going back through some old questions, and wanted to see if you got anywhere with the battery issue?

Merry Christmas

No, I did not get anywhere yet. I contact Maxim about it and the told me to talk to Gateway about the problem. I will try it after new year. Thank you for interest, Merry Christmas and Happy New Year.
