K3 automatically restarts - Page 2

That's a completely different situation. Swapping batteries is straightforward; swapping screens isn't.

screen swap is about a 20 minute job.

battery about 5 mins.

Have a very tiny screwdriver handy.

I could be wrong... (only about the third time today so far) but I got the impression he was going to try and do something with the others. I agree, changing the battery is almost trivial.

Is three years with a Kindle (Keyboard) the norm for how long the battery will last? (I know it depends on how much you read). I figure something like perhaps 20 charge cycles during a year for a total of 60 during a three year period. Let's be generous and extend that to a total of 75 charge cycles. Shouldn't it stand up to more?

I'm asking because today I had to reboot my K3 something like four or five times. Granted I had taken it on a beach walk. There are a lot of benches around the beach here so I would sit down and read for ten minutes before walking further. When I was finished reading I would turn it off but when I wanted to turn it on again I was forced to either slide the switch some four times or hold it for the required 15 seconds to have it reboot. This got me thinking that perhaps the battery has entered its golden years. I should also note that I just stuck it in a side pocket in my shorts while I walked, so don't know if the vibrations had any effect.

It's not just the charge cycles. The chemicals in the battery break down over time, whether the battery is used or not.

I feel like that some days

Right, once everything is apart, I do intend to do a little mix and match to get the best out of them. I read your thread (Fried K3) and looks like it's more complicated than I thought, and despite the effort things could still go wrong (with the waveform or something).

Still gonna try, though

Screens are the issue. There have been several different screens used on the K3 over its lifetime, each of which has a different set of waveform characteristics. If you use a screen which has different characteristics to those stored on the EPROM on the main circuit board, it will work, and "black" and "white" will display correctly (ie you'll be able to read text OK), but you won't have any grey scales, so pictures won't display properly. That's the main "gotcha" when it comes to playing "mix and match" with a K3. You can safely swap anything else (keyboard, battery, etc), but the screen has to match what the motherboard is expecting.

Fascinating. Did not know that. Is there some way to check that before doing a swap? Not that I intend to do that, just curious.

maianhvk · 08-12-2013, 04:23 AM

Ooh, interesting, HarryT! Is there a way to check whether the screen and the mainboard sync?

I'm afraid I don't know. I've just picked up this information from reading posts in the dev forum. Perhaps those more knowledgeable than me would be able to answer.

maianhvk · 08-15-2013, 05:41 AM

And it worked. I swapped the screen and changed the battery. Thanks, everyone, for your encouraging

twobob · 08-15-2013, 10:44 AM

Hurray

Glad you got it sorted.
