    Have an IBM Thinkpad 600 233, 4G HD and 190mb memory....thing
    is that microsoft site recommends upgrading BIOS and requires that a "fully charged battery" be installed during process. My battery is dead so I do not know if the upgrade will work or not :confused: Any suggestions?

    Are you having any issues that are fixed by a new BIOS upgrade? If not, my suggestion is to ignore the advice to upgrade the BIOS. It's quite easy to render your machine inert in the process of upgrading the BIOS.

    Don't fix things that aren't broken. :)

    I have never heard of a recommendation like that. I would presonally have the thing plugged into the Wall when you attempt to upgrade the bios.

    But like Johnwill said, If it aint broke dont fix it.

    My thoughts too...the battery just has to be installed and AC power too. I think the battery thing is for the ACP power management stuff in the BIOS. "If it ain't broke, don't fix it."

    I don't know about the older laptops, but the newer laptops usually won't allow you to go through a BIOS upgrade unless they detect that power is coming from an outside electrical source and not from a battery source.

    A BIOS upgrade is okay to do, if there's a need to do it and not just because an upgrade is available. If a BIOS upgrade goes bad, you're up the creek without a paddle.

    As far as "If it ain't broke, don't fix it", read here.

    My sentiments exactly, but I know it needs something because when it boots up, is shows the memory...192xxx, pauses for about 10-15 seconds, then flashes abit and starts desktop scene.
    No award bios info, devices info, nothing. I installed 98SE on it after wiping NT, (formatting to clear HD). One thing that is also weird is that when I click on the internet access (dialup) icon, it duplicates connection and gives next number. Like Access2, then
    next time it does Access3, then 4. Very strange....so I just click IE and it automatically dials my original Access connection. Some update needed in DUN probably, but it connects and works fine. Anyway, like I said before, the battery thing during BIOS upgrade is some IBM Thinkpad Power Management stuff that measures battery charge and displays power levels and beeps when low or 5 min. remaining on charge. Lots of problems with the old TP batteries, and I can't use mine because it's dead. Hence, I only use A/C.
    Thanks for any comments, suggestions. Good link to the updates info., and I do any and all fixes I feel necessary, according to the
    "Big Fix" program which I found on this site.

    While I don't disagree about driver and O/S updates, I have to stick to my opinion that upgrading the BIOS needlessly is not necessary and ill advised.

    FWIW, many laptops don't show a BIOS banner, since it's a manufacturer's prerogative to put whatever he likes as the BIOS splash screen. I don't think a BIOS upgrade will change that.

    It's also normal for the BIOS to pause after the memory test, it's configuring the MB and I/O devices, and there are lots of timing loops waiting for responses.

    Thanks johnwill, I knew it was "loading" everything because the HD light flickers. Thanks for the advice guys, much appreciated. I
    think I'll leave it as is and not do anything drastic until I have major problems. One question, what would doing any BIOS updates or changes affect?....motherboard? Hard drive? everything? Thanks again.

    Depending on the amount of difference between the old and new BIOS, it can render a W2K/WXP installation un-bootable, I've seen that happen. :) Generally, BIOS updates affect support for various MB devices, and also support for larger disk drives.
