I managed to get it down to 4%

Let's see if deep discharge is the key for now

I can still try that one later

It's losing about 1%/hour

hw do u check the batt

Rip battery

Lipo terrorist cell

i doubt it's going to work because there's probably a cmos battery in there

∆

I doubt there is one, it's way too thin to fit a button cell + Mainboard + screen

@whodun1t when the battery is below 5%, the screen turns on and shows "Low batter N %" for a few seconds

All it need is small corner somewhere

This seems to happen before loading BIOS

i've seen coincells thinner than a die+substrate

that are just soldered straight to the board

How long would such cell even last?

few years probably

a quick google puts it at 10% in 5 years

self discharge

as long as the board has power it shouldn't be drawing any power from the battery

I mean cr927 can hold bios for yeat if not more if properly implemented

if you can work out the device type you can just rip it open and disconnect the battery

and not bother with this discharge shit

yeah like i said, take the screen off

you probably need a heat gun

look up screen replacement tutorials

out of the dell tabs the smaller ones (venue8pro) doesn't have a BIOS battery but the larger ones (venue11/pro) does

might not even to

depending on the unit

actually since it's dell

can you tell me the service tag?

This reminds mw from story of <certain large hardware manufacturer who definetly does not make weapons too> used bake in pcb coin cells to keep system settings no matter what

Was bicht to reverse engineer

are you sure it's a single frame case, because all videos I find on the internet just pop the rear cover off

Can anyone recommend me a portable dac capable of driving 300 ohm speakers? Got hd600's and /hpg/ is useless

>/hpg/ is useless

When was it ever useful

Just like /mkg/

@totally not Cthulhu 🐙 throw a budget for that

before someone drops professional gear
