Disabled graphics card now black screen

So I was troubleshooting a video card driver issue on a Sony Vaio Duo SD11225CYB, using an external display since the builtin screen was dimmed to the point you its illegible. I mistakenly disabled the graphics card now I can't use the builtin screen or the external monitor! I am stuck.  Any ideas?  I googled the model and I can't find anything about it having a CMOS like a desktop does...

Thanks!

Is the machine worth saving? You need a new display at a minimum.  It may be at the end of its useful life.

No, its only a couple of years old and its a customers laptop.  Definitely not throwaway. If I can get the graphics card re-enabled then I would just roll them to a compatible driver or OS.

Since I can't see the screen I would be unable to follow these steps.

I was hoping you might be able to enter steps from keyboard:  enter step, pause, step and so on.

You may need to get the machine serviced.

Last gasp. Steps for resetting BIOS.

I am thinking that if you can shut down, start up , get into BIOS, you might see the screen

If not to all above, get it serviced.

Windows 7 last known good configuratin !

Restart Windows and just before the Windows logo appears  press and Hold f8 Key on Keyboard. If you missed, restart it again.
   Select last known good Configuration and Enter.
   wait for windows to Startup.

Also , shut down and plug in the external display. BIOS does not need much to display. So plug in the external display and get into BIOS. Any luck

Try this:
Restart Windows and press and Hold f8 Key on Keyboard for 10 sec.
then press the arrow down key for six times and then hit Enter.

Can't send to be serviced...I am the service person. Just made a dumb mistake disabling the graphics card. Can't do last known good since I can't see a screen.  External monitor won't work either since I disabled the card.  Only option I can thing of is resetting the CMOS battery but I not sure where it is on this type of laptop without ripping out the insides searching for it which I would rather not do blindly.  I've got an external graphics card being overnighted.  Any other ideas?

remove battery  and remove the BIOS battery for a minute

Tried " Restart Windows and press and Hold f8 Key on Keyboard for 10 sec.
 then press the arrow down key six times and then hit Enter"but still was not successful.
I've also removed the battery for minute or two and that didn't help.  I found out the CMOS is located underneath the motherboard but am a little leary of removing that in this kind of device.  Any other ideas?

At this point, all that is left is trying the new card you ordered.

Did you disable the internal graphic from BIOS or from device manager ?
if from BIOS, the only way to resolve it is  clearing CMOS data by removing CMOS battery.
if you disabled it from device manager there are many ways to fix it.

also if it's from BIOS,  go to a Sony repair center, and ask them to remove the CMOS battery for 30 min.

Hi Ramin - I disabled it in the device manager. To give you the back story..the customer brought the laptop in because she couldn't see anything on the screen.  At closer inspection, I saw that you could see Windows graphics but the screen was dimmed to the point it was unreadable. Did a little research found that her graphics card (Intel HD 4000) is not compatible with Windows 10...however there are multiple registry tweaks to get this card working.  Long story short, not thinking...Using an external monitor, I disabled the graphics card in Device Manager now I can't see the screen or an external monitor. Any help would be greatly appreciated...otherwise I will have to buy here a replacement laptop.
