  • Older models start, no prob there. Newer ones, that don’t have detachable batteries, yes, they can be a problem (sometimes, depends on make and model… usually brands like Dell or Lenovo can make a fuss over it). Even in those cases, there are BIOS mods that remove this limitation.

    Of course, that general advice is good and should be followed. But some batteries will die even if you follow these advices. There were some laptops back in the day that had a recharge cycle counter inside the charge/discharge controller in the battery. They would just die, out of the blue, after, let’s say, 1000 charges. People that were used to having their laptops plugged in all the time, regardless if they needed that or not, spent the recharge cycles a lot faster than people that just plugged in the laptop whenever it was low on battery. This happened because the charging circuit sometimes falsely reports the battery as a little drained (99%), so it will recharge it just a tad. Still, this “just a tad” added 1 recharge cycle to the count. Over the course of a day, this may happen, 10, 15 times, which ammounts to 10, 15 charges accourding to the counter. So, their batteries basically went dead right after their warranty expired. There are ways to reset the counter or completely jump that piece of code, but it’s just not worth it. Too much RCE work for very little gain.

    It’s a shame though… those batteries were still OK. It was just a shitty move from the manufacturers to try and squeze more money from their clients for batteries.


  • Doesn’t really matter, those chargers can take in from about 90V to about 250, 260V. Forget what the sticker says about 110~230, they’re designed for unstable voltage operation (not actually designed for that, but they don’t wanna make different ones for EU and UK/US voltages coz it costs more, plus people bitch about not being able to use them abroad, so they just make the same ones and ship with different plugs). Trust me, they can handle voltage swings pretty darn good. They’re SMPS power supplies, they’re designed to output the same voltage in a very wide range of input voltages.

    If you really think that a battery will help (it might help… in some cases… depending on how it’s built), just leave the battery on even if it’s dead. It might work as voltage dumper in some cases, but as I said, it depends on the design.





  • Nah, I got it set up on a P4 with a 20GB drive, takes about 2 or 3GB. As time progresses, older snapshots get deleted automatically by Timeshift 😉. So, say you got 4 daily set up, 4 weekly and 2 montly. Only the last 4 daily, 4 weekly and 2 monthly stay, the rest are deleted as new snapshots are created. That’s the while point of having this setup, so you can go back in time, but you decide how long.


  • Yep, you’re doing it right… or at least that’s how I do it as well, lol 😂.

    A snapshot is exactly that, a snapshot. It doesn’t take forever to create, like with rsync, it litelarly takes a second, even on very old rigs (775 or even older). It’s basically a snapshot of what the current drive holds. If a file changes (gets added, removed, whatever), the snapshot grows cuz it needs to hold the older versions of the files (the ones saved at the time of the snapshot).

    This might not be exactly how snapshots work in BTRFS, but this is what I gathered from using it with snapshots enabled. The older the snapshot, the larger the size of the snapshot (takes way more room cuz more changes have occured).

    Also, it’s wise to set up daily, weekly and monthly snapshots. I have it set up to hold 5 or 6 (can’t really remember now) daily snapshots, 4 weekly and 2 montly. So basically, I can go back in time for a max of 2 months. I was thinking or raising the montly snapshots to 3 or 4, but I’m still not sure. Still, I wouldn’t go lower than 2.
