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
