eBook Reader Power Management Problems

Typical: 5 weeks after I wrote a review of long-term experiences with my eBook Reader in which I said, “the hardware has worked flawlessly”, I hit a problem last week, so much so I thought I was going to have to send it back to Sony for repair.

The problems started when I ran the battery completely flat for the first time ever. I charged it the next day and, having connected it to my PC in work for about 5 hours, found that it was still flat. I unplugged it and tried again, and it started to take the charge. For the next couple of days, I noticed that the battery seemed to be running down unusually fast: I was finding that I needed to charge it every day. I didn’t notice the cause of this until Thursday: I couldn’t turn the device off [or more specifically put it into standby mode].

I googled this and couldn’t find any articles on people having a similar problem. Some people have had issues with the on/off button detaching, but nothing sounding similar to what I was seeing. I dived back into the manual and found the power off functionality in the top level menu. I never really figured this as a long term fix, but we’re going on holidays in just over two weeks and I was starting to think about the likelihood of a round trip to a repair centre, so I was looking for a sticking plaster. This worked for about a day, but the device became completely unresponsive on Friday night.

I’d tried a few remedies. I had recently uploaded my first PDF content, so thinking that that might be corrupt in some way I deleted it. When that didn’t work I tried deleting everything, using the top level menu item. Either this takes longer than I had patience for [an hour] or else didn’t work at all [my money is on the latter]. Soft resetting, with the recessed button on the back in combination with the on/off button failed as well, and eventually locked the device up completely. At this point I assumed that it was irretrievable, as it was completely unresponsive. I gave it another charge the following morning, and while I was waiting, I tried googling for a hard reset key combination [I had previously googled just for ‘reset’, not explicitly a ‘hard reset’]. This, finally, worked. Unplugging the reader from the USB prompted a reboot. While this was happening, I held down the bookmark and volume key, which prompted the full reset, restoring the device to factory settings. This requires the re-authorisation of the ePub account with Adobe.

With the benefit of hindsight, it was a pretty nasty way for the device to fail. The recovery process was effective, but not an awful lot of use if the device crashes when you are lying on a beach somewhere. It remains to be seen if it’s the start of a pattern or a one-off.

Guitarist…

This is the first time I’ve used my flash with the wide angle lens. I quite like the cutout effect. I took a couple of stabs at the first shot: I was trying something a little more sophisticated, with a reduced saturation, and an extra layer to mix the cut out effect with the unadjusted background. Not really worth the effort to be honest. The black and white looks better:

Water Droplet Macro

A few shots from the weekend, using the flash to freeze water droplets striking the surface of a mango. The use of the mango is purely for the textures. The background didn’t work quite as well as I’d hoped: we have a composite work surface in the kitchen which is flecked with highly reflectively pieces of mineral, and I’m confident that my wife would shoot me if I coloured them in with a black marker :).

I may have another attempt at this: ideally I’d like to get full diameter of the splash pattern into focus, which means pushing the aperture a lot deeper. The main problem was that the ambient light was much too low, even at F8. Another problem I had in an earlier attempt was with the water leaving distorted trails on the image, as there was just enough light across the shutter setting to be exposed, above and beyond what the flash was freezing. I was going to try second curtain, to see if that would help and decided it wouldn’t, so went for the less technical solution of changing where the water droplet landed.
