How does my pc loose it's own internal clock *this* bad when it's battery gets depleted and it's been off the internet for a while?!

@miifox probably only has one battery instead of two like mine

@charlotte even the DS knew how to shut down the system *a little* before the battery was so depleted it couldn't even advance the RTC clock anymore. I've had DS'ses that I haven't used for almost a decennia still keeping track of their clock, my laptop went out of juice *yesterday*!

@miifox @charlotte Most devices like that have a separate battery for the RTC (yes even portables!). And since the RTC doesn't use that much power a simple coin cell can operate them for decades indeed!

@deetwenty @miifox my Thinkpad does, DSes don't and I'm assuming neither does Caro's laptop

@charlotte @miifox kinda surprised then that the DSes can then hold the RTC, the circuitry to prevent the batteries from completely running dry is I believe more expensive than just adding a coin cell

@deetwenty @miifox I think you just need one or two diodes and a transistor

The diodes for lowering the voltage so that the almost depleted battery voltage is lowered to below the gate threshold voltage, cutting the power to the system

@deetwenty @charlotte the DS, especially the Light, doesn't actually feature a ton of in-device space left, both the motherboard and everything surrounding it is pretty cramped. That being said, they even managed to squeeze in a coincell in some Gameboy Advance game cartridges which are positively tiny, so there were probably some other reasons as well
