Things that Absolutely Cannot Happen ... but do ... (Part 2)

Before I went out to London on Sunday morning, I shoved my palmtop on charge for a few minutes. It was at maybe 53% when I had to go get the bus.

That was Sunday. Now it's Wednesday morning, and, it reads 97%. 97% Apparently something in my room is exuding battery mana which my Revo is absorbing and using to charge the battery while it's lying around on the table or stuffed in my coat pocket on the door, where it's been since Sunday night until a while earlier.

I know the battery gauge is a bit iffy, but to gain nearly 80% more power? It loses 6% per day when not in use (to power the RAM and clock), but I've regained that, all the power used on Sunday, and an extra 45% or so on top of that.

Does this mean that I'm going to get arrested by the Science Police for repeated violations of the laws of physics? I need to dig out my sonic screwdriver and scarf and do some investigation.

Was there a temperature change? Warm temperatures can cause batteries to seem over-zesty, but then cold temperatures can allow them go regain a little bit of their juice when under little or no use. We have a whole system for charging deep cycle batteries here, and it is entirely temperature dependent.

huh? There's no way the charge could go from about 20% (or whatever it was at by 1 am Sunday) to 98% (what I first saw when I checked earlier) from ambient temperature change alone.

I think the OS has flipped its lid -- it's a flaw in the software battery gauge that happens when it gets really confused; you end up with a mad random figure that a reboot won't cure. Owing to other hardware failure too complex to mention, I'm going to have to hard reset it and restore from back-up to clear the mess it's got itself into.

Here's my rules for truly weird shit: 1) if no one else is there to witness it, you're probably hallucinating and 2)if it only happens once, it's not worth worrying about. If it's reproducible, then you start investigating.

That said, my first instinct is to make sure your power gauge is working right. Batteries are weird.

I reckon I was saved by the ley lines the other day - my camera should surely have died just a little before it actually did. Don't ask me why...but I think I was so tired the other day that I forgot to charge my spare battery (or so the indicator leads me to believe), and I very nearly repeated a stupid mistake. Mind you, there's a sizable chance the pictures could be crap anyway, but at least I got the chance to take them!

You are right dman. The new glass cube Apple Store is a disguised Mayan temple which acts as a sort of karmic amplifier, intensifying some the complex subatomic forces around New York and focussing them on your camera. Freak atmospheric conditions transferred the effect over the Atlantic to Uilly's palmtop.

Obvious really.

TheMoMan: It's two internal AAA NiMH cells that cannot be removed; the charger circuitry (and sensor array) is all on the motherboard. What's happened is that OS's take on the battery strength has become random -- on occasions the OS reads a figure different to the hardware. Unforunately, the hardware battery sensors don't work any more, so it will only do fast charge (a thermal sensor tells it to step down), and I have no idea how long to charge it for to get to 100%. I can't just leave it on fast charge until it's done, as that will be forever and the battery will vapourise in the process. Another device takes it off fast charge after 5 minutes of sitting at 100%, but that doesn't work either! If you reset/reboot the OS, it doesn't fix the OS battery status.

Hence I can do little but let it drain until it loses all the memory content, recharge it from zero so that the OS starts over, and restore from back-up.

I did send it in for service last year to fix the batteries (assuming they were dying -- it was well over three years old) but after what become a saga in itself, they fixed nothing. I didn't realise until the very end that the batteries were "fine" (getting old, but still working), but the sensor array was broken and I was not getting any working calibration out of it.

dragonman97: I've never seen evidence of low battery affecting camera images. Nor any reason why it should. Besides, the camera should stop running long before that point to prevent it from writing to the memory card on a dying battery, as that can be spectacularly fatal for the file system on the card.

I had something similar happen with a calculator many moons ago.

The rather old and tired batteries typically needed recharged twice a week, but this time they mysteriously 'got better', I got over 2 weeks of solid use out of them, and then they died completely, never accepted charge again.

I never said the dying batteries caused the images to be crap. You falsely inferred that. Rainy weather meant the images might look crap, as the background was nothing to write home about. [Smile]

There is only one conceivable explanation for all this.
