Hello,

I am using a Toshiba Satellite Pro C850 (PSCBXA-00Q004).

The laptop works completely fine with the AC power cord plugged in, but when it is removed it turns off immediately. I replaced the battery with a new, genuine and expensive one and it still does the same thing.

The battery IS recognized by the laptop, It also says it is Fully Charged (100%). When I remove it with the AC cord in, it alerts me that it is missing.

I have installed and updated drivers, updated BIOS, ran battery checks and tried everything I could find on Google, shall I give up?

You may have to. Since you have the exact same problem with new (and genuine replacement) battery, it seems unlikely the new battery is faulty.

And since the notebook works fine with the external power supply/charger, it's not that either.

So that pretty much leaves the notebook's internal circuitry as the culprit. It could be something as simple as a bad connection or solder joint, or a failed component.

What I find confusing is the notebook sees the battery, then reports it is missing when you unplug the charger. The only thing I can suggest is you calibrate the battery (if possible in this case) to the notebook. This procedure should be in your notebook user guide. This procedure synchronizes the batteries charge rate to the notebook's battery charging/status monitoring circuits. On my Toshiba user guide, this procedure is shown under "Maintaining your battery".

what happens when you power on the laptop from just the battery?

Thank you so much for your replies! With just the battery in, the laptop doesn't turn on or respond at all.

Very frustrating, appreciate you guys though.

I agree. That's what it sounds like to me as well.
