iBook Battery buggered

I am currently getting roughly 35-40 minutes of life when the power settings are at highest performance.

Hi all,

My iBook battery went through the problems of the 10.2.8 update but seems not to have recovered since. (Late Jan 01 dual USB 600Mhz)

I am currently getting roughly 35-40 minutes of life when the power settings are at highest performance. I only have airport running, plus MacSoup and Safari, so there is no great power drain app making it so low.

My iBook is covered by Applecare to the end of next year, but I would like to to have this sorted out now as 40 minutes is not what I call workable.

Any idea on how to approach this with Applecare? Do they feel that 40mins is normal battery lifespan under highest performance. I certainly do not think so, and recall it being over an hour under similar circumstances.

Thanks Nic

I'm afraid that after three years, in practice 40 minutes isn't at all bad. Lithium ion batteries are delicate things; just existing seems to tire them out. If you had problems with 10.2.8 Mk 1, then that would be all the encouragement the battery needed to die for ever.

You can try Applecare, but I'm not at all sure that it will cover the battery after two and a half years- I thought 18 months was their limit.

Result!

Just spoke to AppleCare. Made a point of telling them the following:

1/ iBook has had a handful of charge-discharge cycles as I have chargers both at work and at home.

2/ It was working just fine prior to the 10.2.8 update.

3/ I have tried their instructions of reclibrating the battery and resetting the PMU.

They are sedning me a new one in the post. The iBook will be 2yrs old this December, and has the extended AppleCare warantee.

Thanks!

Now I feel glad to have paid the extra 180 for AppleCare, although the purhcase was prompted by the fact that repairs to creeking case and dodgy CD writer were not sorted out a few weeks before the one year of warantee lapsed.
