Won't sleep on low Batt - Auto Shut down.

[pogomonkeytutu]

I started using an O2 Mobile Broadband dongle last month and since then, I have been having a few issues with my Powerbook G4 12".

The battery is ridiculously drained now, lasting maybe 30 mins unconnected to the cable (even less with the dongle plugged in - 15 mins at most.) and will auto shut down even when the battery level is around 40% remaining.

And when it shuts down, upon restart the time and date are set to Midnight, 1970.

I've looked at my energy saving settings incase something had changed there but it hasn't.

Anyone have any advice?

Use iStat Pro (www.islayer.com) or Coconut Battery do see how healthy your battery still is.

With health I don't mean the current charge but the full capacity when charged.
So you could have a health of 40% (but still show a charge of 100%), which means the battery will only hold up to 40% of its original charge (when you bought it new).

Wow, it says I only have 35% health! Is there any way that the dongle could have done this? It was fine before I used it and to be honest, if it was the fault of installing the mobile broadband, I'm not overly happy!

Thank you for your advice, it's been very helpful!

How old is your battery?

How old is your battery?

I brought my Powerbook in 2005. However I received a new battery from Apple in 2006 (Or early 07... not sure which) as part of the battery exchange.

If I'm going to have to buy a new one, can anyone suggest the best place? I'm UK based and a snob for branded hardware so it would have to be an official Apple product unless anyone can convince me otherwise as to a better option.

Can you tell us the cycles of the battery?

If you're under 300 cycles (and under 80%) you could maybe get a new battery from Apple.

And I don't know about a USB dongle that drains a battery so much that it even loses its health.

According to the thingy, 850.

The a battery health of about 35% sounds right.

You need to get a new battery then, Apple won't replace the one you've got.

Try eBay or other sites maybe, even the Apple Store might offer some old batteries.

They will cost around 129€ (around 400 GBP according to the Unit Converter widget, but more like 110 GBP. wow the Pound has lost some value, 32 months ago I still could get 75 GBP for 100€).

If anyone can suggest a good make, I would be very appreciative. I don't want to buy one to find it's not the best quality and end up having to fork out another £50 in a years time.

Apple has them for £87:

You might be able to find one cheaper from ebay, but it will be a knockoff, so there is a good chance it will be below average quality (or not work at all, or catch on fire, etc).

FastMac and OWC both make very reputable batteries; their batteries are cheaper, equal or higher quality, and have greater capacity than Apple's OEM batteries.

Cheers for all the advice. I'll get hunting!
