Turn on without battery?

[euplio]

Try to disconnect the battery cable and turn it on while charging cable in and let us know 😛

My battery only charged up to 10%. I have removed it and I have done everything but I have not been able to revive it.
The battery is removed, I connect the charger but it does not turn on (like a tablet or a mobile).
Could you fool the motherboard and bridge (connect) from the battery pin to the charging hole? At least it could be used connected… ?

put the dead battery back in, apparently it needs the charger electronic what is inside the battery.

Thank you for the reply but if I connect the battery, it’s drained in 15 minutes and when the battery is spent, the laptop doesn’t turn on again.
It seems that I have to survive with an overvoltage to reload up to 10%, but when it is spent, connected or not, the laptop does not turn on.
It could be that charger electronic is broken…
I do not know if I explain myself well, sorry. I am Spanish. ?

So battery charged 10%, charger plugged in and the Jumper shuts down in 15 min?
Is that correct?
and don´t worry about Spain, Techtablets sits in Denia, Alicante  and I am from Valentia. But we all speak English.

Yeah, the time it takes for that 10% of battery power to run out (around 15-20-25 minutes. It depends how you use it).
What I had in mind was to weld where the battery pin goes to the charging hole to trick the laptop into turning on without the battery in it. I don’t know if that can be done.

Something like this: (Until the 6:56)

what I do not understand is how a pc can drain a battery if the charger is plugged in.
install batterybar (PICTURE) and check what is going on and put a wattmeter between your charger and the power outlet.
seems to me you charger does not put out enough power to keep your pc running.

what is it 12V 2A
maybe try another charger.
if the tablet in the video is a celeron n3450 than it should work, if it is not then ???

Thanks, @chupa. I have installed BatteryBar, HwMonitor and some other apps to monitor the battery, see its “real” capacity, etc …
I have tried with 3 different chargers (12V-3A (2 of different notebooks) and 12V-2A). The computer does the same to me. =(
With the laptop plugged in, the battery goes down little by little, even without doing anything, even leaving it only on the desktop and without touching it.
I found a page to buy the original battery and I was in contact with them for several days. They answered me and told me that in the end they had not found spare parts for this model. I post the web:

I found info from a Russian user who disconnected his dead battery and the jumper functions, it just forgets the date when unplugged.

Regarding your fix with one cable, the first solution will not work, but the second with the blue lenovo he connects to the charging board and that could work when you remove the batteries and connect there somewhere.
My tip: read my post and order new batteries and leave the jumper off with disconnected battery so long.

can you post a picture of batterybar , I want to see the  discharge rate and other info.
