I have a new X220 laptop. Since I have a desktop at home so I only use my laptop during business trip ocassionally.I always have my battery removed from laptop after each usage.I heard that this can prolong battery's life...
However, every time when I power up my laptop, it turns on and then turns off itself. At first i was wondering if this is due to the lack of battery. After connect it to my A/C source, it turned on and said System Date and time error and I needed to go into BIOS to reset it.
This is new to me as I didn't encounter such issue with older version of thinkpad. Did I miss something here? Pls help. Thanks!!

Sounds like you may need your CMOS battery replaced. It should not be a problem after you replace it.
Also, if you want to prolong your battery life, just detach it during computer use (use AC only). Then while it is turned off I would actually plug it back in so your computer is never without a power source for an extended period of time.
There are many studies suggested that battery life will start decaying after 2-3 years regardless what method you use. I actually recommend making the most use out of it. Hope it helps.
