That's right: those things have a charge controller which should take care of that (at both ends: overcharge, because *boom*, and that's expensive for the manufacturer, ask Samsung [1]) and deep discharge. Unless the charge controller is somehow defective -- and they are all a bit, because it's a tradeoff: if you just allow 70% max charge wrt what is usual, your battery pack will live quite a bit longer, but you can't boast "8 hours" or something. I wouldn't expect that from Lenovo, but what do I know? regards - -- t -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAljYxKsACgkQBcgs9XrR2kb/XACdFq+49NKjlcwpICJgH1cdQY2j +L8An2guyN7z1N42aGJ3OGNu5Fp8Asg/ =ZFWi -----END PGP SIGNATURE-----
