Tried to close. Soldered the battery - also useless 0
Please tell me what to do, I just have no idea. And please tell me in more detail the procedure for closing contacts, maybe I'm doing something wrong. Thanks in advance.

The battery must be pulled out for a long time so that the biome has time to reset

Remove the bios battery and laptop battery. Leave for 1 hour. Then long (about a minute) press the power button. Leave for some more time. again click on the enable button. Then solder it back and it should work.

When updating the BIOS, the settings will also be overwritten. Try to make a bootable CD with autorun of the BIOS firmware utility
. If the system boots and you can somehow control Windows (touchpad?), you can flash it from under Windows . You
can also use a programmer, but this is quite hardcore for an ordinary user. The programmer costs 200 rubles
