Can I operate my T21 w/out a battery in the battery slot?

Why would I want to?
Don't really know, other than to rotate batteries for maintainning charges in all.

Kyocera,

Thanks; I made a point of asking since I believe I fried a HD on a Dell CPxH I own by not having a battery in place when starting on AC power; I could be wrong and maybe the HD was ready to fail. Maybe the extra step the CMOS had to go through to recognize the fact that the battery was not in place caused confusion w/the HD- I don't know, but I figured it was exactly this config that caused the Dell HD to blow.

Thanks again.

Well, that being said I did not elaborate but I am one of those that believes it is important to have the battery in place. Some say they don't use the battery much - some, like myself think in the event of a power failure it will help maintain your system continuity. A drop in voltage could cause power supply problems over a period of time. I used to work on large network printers and strange intermittant problems were often traced to bad or poorly wired AC outlets. A check with a multi meter or suretest is a good indication. Power supplies in laptops are tiny and can not take a lot of voltage flux.

I would agree with you in that current battery chemistry is classed as consumable.

If you use it or not, the battery will still lose half it's chemistry in 3 years if not more.

The batt. in mine prob. dates back to 2000? It's probably only good for 1hr or so now.

If you want to keep your T-series, buy some batts off ebay?

With regards to mains line voltage fluctuations; if you want, you can get a UPS + Surge Protector to guard against stuff like that. Although all bets are off as to what your system will do if the AC line starts going crazy and surging on/off at high frequency....I do know, however, that stuff like that can fry systems. Those occurances are rather rare though. :)

Not as rare as you might believe, depends on your location.

Family members in Tulsa this past week suffered a home fire, as did their neighbors, when they were the recipients of a massive voltage surge.

Fried ALL of their electronics, even her work laptop which was on a UPS! Basically, fried everything that was plugged in or connected to the mains, whether it was "on" or not..

Firemen reported the romex (metal clad) wiring in their attic was glowing red!

Needless to say the entire house is being rewired. Very fortunate it happened during the day as no one was injured.
