IBM T30 laptop- replacing CMOS battery

I just bought a replacement (non-IBM) CMOS battery and installed it in my laptop; it didn't appear to change the boot sequence (currently boots to setup screen where it asks the current date/time). I pulled the new one and noticed that the leads for the new and old batteries are reversed polarity (at least the colors are reversed). The guy I bought it from says this isn't a problem. Everything I know about electricity says black is negative and red is positive, so seems to me it would make a difference if the battery is installed with reverse polarity. Anyone know if these off-brand CMOS batteries have leads that colors/polarities are switched? Thanks

Provided the laptop booted (albeit to requiring bios set up), all is well. The data such as time needs to be re-entered manually, because since the battery is required to maintain volatile memory, when the battery goes flat or is removed, the data is lost. Re-enter all data, including boot sequence (i.e. IDE 0, CD-ROM/DVD)! exit saving to CMOS. should reboot to OS.

Try to see the battery, there is a flat suface. The flat surface is + and the reverse is -, Yes the vendor is correct the black is negative, and red is + , However did the original battery is lying down to the mainboard , exactly the flat surface (+) is visible(100%)

Bought T30 used about 5 years ago, neeeded to change CMOS but has a Lock. Took out Yellow CMS battery to clear CMOS. Now can not get in computter at all. Please I am 62 years of age and enjoy my samll...


Sorry to hear of your problem. I'm not too familiar with the T30, I jumped over that series and went from the E600/X600 directly to the T4X. I'm going to guess that the T30 is similar to the X600 as it was IBM in the same era. When I've replaced the CMOS in the 600, you have to sett all of the time and date clocks all over again. You should get a couple of error codes on the screen followed by an entry into the bios.

I want ot reset BIOS password for IBM T30 model laptop as i forgotten it


To reset the BIOS read the information from this link.

In case of your IBM laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

IBM T30 - power issues


You might try cleaning the battery compartment. Makeing sure there are no damaged pins. Often times even a single messed up pin will cause this. Also this is a very good indication of adaptor failure. If you haven't allready I suggest getting another ac adapter specific to you machine. Even a substitute will casue the same issue you are now experianceing.
