Information about the problem of early dying batteries on Thinkpads of the 600 series.

Problem description

The charge indicator falls from some still quite high (between 50% and 95%) charge state to 5%. This happens only on batteries which have gone through some recharging cycles already.

Affected Models

  • Thinkpad 600, 600E, 600X

Affected Operating Systems

  • all

Status

  • Raph Levien has collected comprehensive information about this phenomena and possible solutions in 2002 on this page: http://www.levien.com/tp600-battery.html
  • Another possible solution is to buy an external battery pack.

It has been the experience of some users, including myself, that the batteries perform far better if you _never_ charge the battery while the computer is on. The area around the battery gets quite hot while using the laptop. Charging the battery at that temperature seems to be a bad idea.
