              DIY: Modified smart charger for all types of batteries
              by dbuergi
              Hi all,

              sometimes i'm in need of a charger / tester for very small batteries and even if my multimeter doesn't show anything there is a chance that a smart charger helps to revieve. I'm happy with my Keenstone smartcharger and i made a small mod just to use it with smaller batteries like in smartwatches or even camera batteries with special contacts.

              Soldering wires on the charger contacts and using needles as probes. I covered both with a shrink hose with integrated solder.
              My first work was to bring my Samsung watch battery back to life with was not recognized...

              ASUS X54H laptop thinks it's always charging even with charger unplugged
              by flat-earther
              The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

              Windows also shows ''Plugged in'' when charger is not connected.

              This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
              Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
              If I let battery run out and say it has 3% Windows will...

              Lenovo T460 Only Charges on One Charger
              by motormayhem
              Laptop Question
              Hello,
              I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).

              A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when...

              Drive SMART status not showing up through RAID controller?
              by canadaboy25
              Hey guys,

              I have an Asus M5A99FX Pro R2.0 motherboard with AMD RAIDXpert. I set up a 1000GB RAID1 array on it. This was about 8 years ago. Every once in a while, a power outage or something would knock one drive offline and degrade the array. After a reboot the drive would be back online and it would rebuild just fine.

              Recently, a drive dropped offline and the array became degraded. I figured it was no big deal and rebooted then set it to rebuild overnight. The next morning I took a look and both drives had dropped offline at 70% rebuild. Uh oh.

              I rebooted...
