Hi everyone
It looks like I need to replace the battery in my precious K4 NT. The question is: will I lose all the books that are already there? Should I back up these books before replacing the battery? |

It is always good to backup, but changing the battery should not harm the books because they are in the same flash memory as the operating system.

My Kindle 4 NTs (I have multiple NT4 readers) just downloaded operating system version 4.1.4 from 4.1.3 when I charged them up and enabled wifi. I installed the update. Any members know what the update changes? Not obvious to me and the update does not include any info on changes or enhancements. Be nice if Amazon included info even if the update is just bug fixes.

Hello everyone, i have a kindle 4 NT (2012 edition), can you give some tips and advice about how to remove the dirt stuck on the back panel in a safe way.

Isopropyl alcohol has been my go to for quite a while, and I can vouch for it on a K4. Might be tricky to get ahold of, depending on your location. Pharmacies should be able to get it, but may not be allowed to sell it to you

Microfiber cloth is usually a good bet. You can possibly start with simple cotton pads to get the worst of it off, first.
Note that I do insist on pure (>90%) *isopropyl* alcohol: it doesn't leave any trace, and it evaporates quickly. (Speaking of, fumes are not great for you, use in a ventilated area). Last edited by NiLuJe; 05-06-2020 at 03:52 PM. |

I don't have a citation, but I thought that alcohol + water make a better solvent than either alone. I guess it would dry slower, but thin film will dry reasonably quickly and you shouldn't leave much to dry or it will leave behind a bit of whatever you cleaned off that is soluble. |

@j.p.s: It's better for *medical* usage (e.g., rubbing alcohol). Here, you want to avoid residues when it evaporates, so if you were to try that, I'd recommend doing it with distilled water.
The tag is gone on mine, but it's medical grade, so I'm pretty sure it's like 99%, and I've never mixed it with anything myself. But, yeah, it can be, that's often the case with water and/or ethanol in stuff like glass/screen/windshield cleaning fluids. As it can be one of the main ingredient in hand sanitizer, getting ahold of some might be especially tricky in the current context ![]() Last edited by NiLuJe; 05-06-2020 at 07:21 PM. |
