726th post: PC Issues

A bit of a background: I have two desktop PCs from around 2009. A Dell and a Lenovo. These aren't exactly great as they were acquired used and appeared to be used office PCs. The Dell was used as a family PC upgraded with a low-end graphics card in 2014, whereas the Lenovo was just sitting around not being used other than as somewhere to store copies of files from elsewhere.

There are also two laptops from 2008 and 2011 that have since become impractical to use. Apart from RAM, hard drive of one of them, and some lithium-ion cells from the battery back (may have mentioned it when I talk about power banks), none of the remaining parts are reusable.

Since around August 2016, the Dell desktop PC failed. Initially, I thought it was just the capacitors as a few on the motherboard were leaking, but (after waiting weeks for parts to arrive) that didn't work. Hadn't touched it since, other than transferring usable parts to the Lenovo PC. These were the graphics card mentioned abov…

725th post: Annoying power bank

(A short quick post here when I realized it was getting too long while writing series of tweets.)

Just bought another power bank case without cells as replacement of my oldest power bank with 4 cells, but the next oldest that is still working (2 cells) has proven to be more annoying to use these days. I have opened it up before and know it uses two li-ion 18650 cells. The same cells used in laptops with removable battery and Tesla cars.

Part of the case comes off on removing charging cable on the USB micro-B end. On output end (USB standard-A), some plugs are either too loose or huge to fit it in properly without a pass through device like a USB charge doctor, which in itself adds to the bulk and consumes more power.

I thought its "discreet charge indicators" was neat, but proved annoying to tell if charging when looking at the opposite side. The wordings on it has faded away, so you can't tell which side the indicators are at as the design looks similar on both ends.
