I don't see anything unusual in that one.
Lets see what happens after you update it.

Ah, on your Kindle, rename the first report so you don't accidentally over-write it.
(Well, I guess you could re-download it from your own post.

I have, though it all means nothing to me, but if it can help you lot work out why some people have battery problems...

I have updated the PW2 but I seem to have a little problem in that I open KUAL and click on CPU Report but nothing happens

That is extremely odd.

All of those things for supporting the cpuReport are in visible USB storage **only**.

Hmm...
It does depend on Lua being installed in the Amazon image -
But that would be hard to remove - the GUI window manager is programmed in Lua.

Does everything else about KUAL seem to be working?

Well MrPi doesn't seem to want to do its thing either. I get the 'launching the MR installer' message and that's it - nothing happens and packages don't get installed and remain in the folder.

So it looks like something is wrong somewhere

however I hadn't used it for months, since getting the PW3, and I was going to factory reset it and stick it on ebay anyway

This may be a new change at Amazon, try running the 'hotfix' -

If MrPI can't run (it probably can't) -
then put the hotfix update in the visible root of usb storage and try the 'update my kindle' menu choice.

(Amazon just stepped on Geekmaster also - he will not let that slide unless he has changed a lot.

)

Now it's getting *really weird* after the hotfix, MrPI has happily installed the goodies, however I'm still not getting a new report generated from CPU Report in KUAL

Yolina · 04-04-2016, 04:24 PM

scrap that, all good

I've deleted the old report from the Kindle just in case, even though I had renamed it, and re-ran CPU Report and it worked this time.

Well, that confirms what Amazon is doing -

Question:
Did you have to use "Update My Kindle" menu function to run the 'hotfix' package?

(I think that 'hotfix' package is going to become very popular all of a sudden.)

(don't feel bad you 7th gen owners - Amazon just broke my K2 installation of KUAL also - while I was looking at it.)

Yep, MrPI was sulking and didn't want to know.

Oh and this one's a PW2 2GB, so 6th gen?

And a K2 is a 2nd gen.

I'll start a thread on this subject -
You can be sure they are not just picking on MR members.

Changing direction here slightly... I feel like a field reporter!

PW2 customer on Amazon review stated his PW2 started having severe battery drain "one month beyond 1 year warranty" He didn't associate his troubles with the update from 5.6.5 to 5.7.2.1 initially, but stated

Sometimes I would turn it off for bed and wake to find the reader totally dead. No screen of any kind. Charging would bring it back to life.
I tried Amazon support. Being one month past the warranty period the only option offered was to buy another one with a $15 courtesy credit

I asked him if his battery drain issue started after the 5.7.2.1 update and he responded that his new current OS was 5.7.2.1, and wanted to know how to get a newer OS. I posted links to Amazon OS update pages for his model.. he did a manual download and update to 5.7.3 the next day. He stated he would let me know about his outcome with the newer OS update...

I then requested to find out his PW2 model number, in case there is any correlation between battery drain and the storage 2GB vs 4GB since that is an obvious difference in PW2's (but I am sure not the only one). I walked him through getting to the "device info" screen and wanted only the first 4 digits of the serial to see if there is any trend to be followed...

Here is his answer back:

The model number of my Paperwhite is DP75SDI. The total device memory is not listed in the device info screen.

Hope this helps.

So far the battery usage seems to have returned to the normal pattern. Another day will give more information.

Where would the "DP75SDI" model number come from "on the device itself"?
I did an online search and that number is an Amazon number for the PW2, but on my PW2 2GB on 5.7.2.1, it is not in "device info"

1. Anyone on 5.7.3 who can check "device info" to see if serial number still appears there?

2. So far this customer has normal-working PW2 after it was given up for dead

Continuing to investigate (though if update to 5.7.3 fixes the battery drain, that may become an automatic recommendation for "mainstream" users)

______________________________________

My PW2 2GB on 5.7.2.1 which got registered 2 days ago and then was sleeping in airplane mode had no noticeable battery drain after 48 hours.

It now has the wifi turned on to test the "magic folder" to block OTA update and to see if wifi has any bearing on the battery drain problem. That unit cannot be JB'd currently so no "battery status indicator" can be installed to give a number instead of just looking at the bar meter

Hope this helps

"Where would the "DP75SDI" model number come from "on the device itself"?"

No where.
On the box maybe.

That DP75SDI was mentioned here recently (within a week? maybe) -
That post/thread leads to finding out the 4 character model number.

I was party to the exchange, but can't recall what the resulting model number was.

I only have a PW3 original box here, and no where on the outside of the box is a different model number than appears in "device info"

On the end of the box, there is a barcoded DSN (DeviceSerialNumber)?? that corresponds to that unit's serial

I may ask him again to check "device info" again...

So I went digging by reading one of those reference posts further and found this:

https://www.mobileread.com/forums/sho...5&postcount=88

That member states that "DP75SDI" could be found in the "manual in the box"

That was a PW2 from Brazil, so it must represent some kind of alternative Amazon model designation which is different from the "nicknames" used here

Also did a search on ebay for "DP75SDI" and it showed 37 listings, all referring to Paperwhites, using that text either in the title of the item or within the body of the listing

It also showed up here: https://wikidevi.com/wiki/Amazon_Kin..._WiFi_(DP75SDI)

Probably much ado about nothing, but keep it in mind in case that "model" number is mentioned again or one similar to it
