Lenovo Ideapad 700-15isk Stuck on boot menu during BIOS update

2020-09-23, 8:47 AM

Hello

 

I've downloaded the BIOS update from here

 

https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/700-series/700-15isk/downloads/driver-list/component?name=BIOS%2FUEFI

 

Followed steps in ReadMe, install process started, then accidentally computer restarted and stuck on Boot Menu. like in the photo.

Hello Arm_Pirate

 

Welcome to the Community Forums

 

BIOS updates are crucial updates, but they are also the most volatile ones if they go wrong. Normally a BIOS update will take around an hour to complete. Which is why the general rule of thumb to go by for laptops is that the AC adapter always needs to be plugged in, and the battery needs to be at least 30% charged before beginning the update.

If at any point during the update it gets interrupted. F.ex : There's a power shortage in the house, or the AC adapter wasn't plugged in or there was less then 30% battery charged for it to finish, then it can risk serious injury to the device. This is what's called a bricked computer that will most likely be needing a repair.

In the event the BIOS update finishes the update, and something has gone wrong, or the BIOS update failed during the update so that it black screens, it can most often then not be fixed by doing a hard reboot/cold boot.

 

Step 1. Hard Reboot + Static Discharge

- Remove all cables attached to the device (power, hdmi, external mouse/keyboard, etc)

- Press and hold the power button for 5-10 seconds, until the device turns itself off.

- Ensure device is switched OFF

- Hold down power button for 40 seconds

- Wait aprox. 20 sec

- Connect the AC adapter, then let the device charge for 2 minutes before starting it back up.

 

Step 2. Try to boot it through Recovery.

- Make sure the device is switched OFF  

- Press the Novo Button

If device does not have a Novo Button:

- Perform a restart while the computer is booting 3 times in a row.

- On the 4th boot, see if it will enter Advanced Startup Options. Enter the UEFI Utilities then:

 

BIOS reset

- Navigate to the EXIT tab

- Press "Load Default Settings" / "Optimized Default"

- Save & Exit changes

 

 

Step 3. Open the device and physically flash the BIOS by removing the Lithium Battery (CMOS battery)

You'll have to check the Hardware manual for your device to see how to navigate to this.

The HW manual is under "Knowledge Base & Guides" on the Support Page, then the "User Guides" section.

Best way to see what the CMOS battery on a laptop looks like is to google it, as it differs a bit.

The most common one looks like a small silvery coin.

**NOTE: Only perform this step if the device is outside warranty.  

 

Also have a look at this thread for BIOS Recovery (The steps should be fairly identical, but might differ in some areas)

 

If the device is still within warranty and the device is bricked, I'd suggest contacting Lenovo support for your country directly (mail, e-ticket, phone) and see what can be done. Most likely it will have to be sent in to be assessed by an authorized technician.

 

Good luck

 

Regards

Thanks for your answer.

 

Actually AC power was connected and now power interruptions exist. Compter restarted by itself accidentally.

 

So I've tried to remove static electricity us you suggested but the picture is totally the same. The worst thing is when I am trying to use USB boot flash option computer again returns to the same state :(
