Boot Freeze and cmos problems

[Stan_T]

so I found my old Stream x360 (last used 4 years ago)  laptop and tried to start it up but I got a cmos checksum invalid. It saits that it was going to repair it but when i waited the error disappeared and I was left with a black screen. So I waited but nothing popped up so i pressed f11 to get into system recovery because it wouldn't boot into an operating system but when I pressed f11 nothing happend. There was only some text in the bottom left on the screen and that says ''F11...System recovery" but nothing happens i even tried to press F11 again or hold it down. But norhing happend. Even F10 doesn't work. What should I do now? Btw this computer doesn't have a ceperate cmos battery. It uses the battery of the pc itself. (sorry if i'm saying wrong things because im not an expert"

Hi,

If you turn off the PC by holding power button. Turn on PC and continuously and repeatedly keep pressing ESC does the startup menu appear? Are you able to enter BIOS from here?

Let me know,

Hi

I would make a W10 Repair/Recovery/Rebuild/Re-Install media from here...

IF/when it boots...

If you can set/reset the Time and Date in the BIOS that may help.

Nope... It doesn't work I just get the message in the left bottom screen ESC...Pause startup and i tried pressing it again and holding it. Nothing works. I think the bios is corrupted or something like that. Also when i turn it on and hold the power button for 3-4 seconds i get a black screen with a blinking caps lock key. it blinks 2 times every 5 or so seconds. But i can't find some useful information about this and I also takes ages with loading to get a new bios driver. (im trying to install a new bios on the pc but i don't think it´s going to work.

[Stan_T]

that´s the problem... It doesn´t even reboot

[Stan_T]

nope

Hi

Depending on the age of the PC and the BIOS vendor...

EG:

2  --  MEMORY PARITY ERROR

2  --  ROM FILE NOT FOUND IN ROOT DIRECTORY

~~~~~~~~~

LED blinks twice.

BIOS

BIOS corruption failure.

Reset the CMOS:

1 Restore BIOS if available. (If you can access the CMOS battery, pull it out and re-seat it.)

NB:- See the Services Media Library for steps for your PC.

2 Press the Windows  + B keys to do a BIOS recovery.

If the error persists, replace the Main-Board.

yeah i already tried power butten + windows key + b but it turns on the pc and instantly turns it off

And my pc doesn't have a cmos or i don't really know but when i opened the laptop there was no cmos battery (don't really know how to say this). Because the it uses the main battery. and that battery is dead or something because i need to keep the pc on the charger otherwise the pc would not work.
