USB port does not work after changing CMOS battery

[Edder]

After changing the CMOS battery (BIOS) the USB ports no longer work, so I can't access the bios to check what happened because when windows boots it is also not working. How do I get the USB ports back to work?

Hi @Edder 

Boot to BIOS:

1. Enter Windows Settings > Update & Security
2. Press Recovery
3. Press Restart now

Windows will reboot into Advanced Menu

4. Press Troubleshoot
5. Press Advanced Options
6. Press UEFI Firmware Settings
7. Press Restart

Hi @LeonWaksman ,

I appreciate the attention. I can't do anything because no peripherals work. Even accessing the BIOS, I can't select any options because the keyboard and mouse don't work.

First of all, I would be suspicious of the battery being wired backwards if this is happening.

Regardless, let's try bring up the Power Button Menu (power on holding the power button down for three seconds or until the power LED turns amber). USB will always work in this menu (if it doesn't, something has happened in hardware; see my first comment). From there, you can use the F2 key to get into BIOS Setup. Once in BIOS Setup, use F9 (followed by Y) to reset the BIOS Configuration and F10 (followed by Y) to save the configuration change and exit BIOS Setup.

Hope this helps,

Hi @n_scott_pearson,

First, thanks for your attention.

The battery is connected correctly.

I did the procedure and even then I can't change the options on the keyboard, it doesn't give any signal at all. When I connect a mouse to the USB port, it turns on the optical light but it also doesn't work. I tried to restore the bios through the safety Jumper, but I can't start the process. I must be doing something wrong.

We have seen problems with the base formatting that comes on some USB flash drives. Our workaround (determined through trial and error) is to use the Windows formatting tool (no other) to reformat the drive, using the FAT32 file system (no other), with the Quick Format option disabled. If the tool doesn't offer FAT32, then the flash drive is too big (get a smaller one). We also recommend using the USB 2.0 flash drives, not USB 3.x flash drives.

Note also that, for NUCs that use the Aptio 5 BIOS core, it is important to use one of the BIOS Recovery packages provided in the Download Center. This is because, for some, the location and name of the .CAP file is important. I am not happy that they did this, but it is what it is.

Hope this helps,

Hello @Edder 

What is your NUC model?

Leon

[Edder]

Hi @LeonWaksman ,

Sorry I didn't speak before, my model is DC3217BY.

[LeonWaksman]

Hi @Edder 

1. Did you used USB 2.0 flash drive (USB 3.0 is not supported on your NUC)?

2. Before starting the recovery procedure, reset the BIOS to default settings: 
      - power ON your NUC with Yellow Configuration Jumper installed between pins 2-3. You should see the  Maintenance Menu.

       - Click on F9 to set BIOS to default settings.

       - Click on F10 to save the settings.

       - Power  OFF your NUC and remove the yellow jumper.

3. Insert the USB drive with the BIOS file GK0069.bio into rear USB port (do not use the front port for this).

4. Power ON your  NUC and the recovery process should start after about 30 seconds and shall end after 3-4 minutes.

5. Depress on the Power Button until NUC switches OFF. Remove the Power cable and replace the Yellow Jumper Between pins 1-2. See page 44 in Technical Product Specification.

Hi @LeonWaksman 

1. I'm using USB 2.0 flash drive.
2. I cannot perform this procedure because when accessing the menu, my keyboard does not work to choose the options.
3. I inserted the flash drive into rear USB port.
4. I removed the jumper and power ON my  NUC

When turning on my NuC it turns on the flash drive light and keeps the cooler running but does not start anything on the monitor.

Hi @Edder 

Try the iflash method for BIOS update:

1. Download GKPPT10H.86A.0069.BI.zip archive and extract it on your drive.

2. Prepare bootable USB flash drive .

3. On this drive prepare Autoexec.bat file with the following command:  IFLASH2 /PF GK0069.bio

4. Copy the IFLASH2.exe and GK0068.bio files to this USB drive.

5. Remove the SSD with Windows from your NUC.

6. Insert the USB drive with the IFLASH.exe and the BIOS files in the rear *USB port and power ON your NUC. The NUC should boot form the USB drive and the BIOS update process should begin.

7. After BIOS update finishes, power OFF your NUC and reassemble the system SSD.

Hi @LeonWaksman ,

1.  I put the files (IFLASH2.EXE and GK0069.BIO) in root the flash drive(2GB) formated FAT 32 with option quick format disable.
2. I created a file with the name Autoexec.bat in root the flash drive.
3. I removed the ssd.
4. I inserted the flash drive in the rear USB port and turned on the NUC and the following message appeared: ''A bootable device has not been detected.''

Can you tell me if I can get the HEX or BIN file to re-record my bios with a recorder?

[LeonWaksman]

Hi @Edder 

The USB should be bootable.  Only after creating bootable USB, copy the autoexec.bat file and the IFLASH + BIOS files.

Hi @LeonWaksman 

I did the following procedure:

After  put the files in the flash drive, but the same message appears.

[LeonWaksman]

Hi @Edder 

The support in this forum is supported in English. I can't translate the linked document in Portages in order to verify the procedure you have used.

You may check if you have bootable drive in other PC with legacy boot enabled. Remove the autoexec file before checking. After successful boot you should see the Command Prompt window. If in other PC this drive is bootable, it should work in NUC also.

Hi @LeonWaksman ,

I performed the bootavel unit verification procedure and it worked on another pc. I believe I'm having problems with my USB ports, but I don't know why, because before the battery change they were perfect.

[Edder]

Hi @n_scott_pearson,

I performed the following procedure:

- I formatted a  flash drive (2GB) on windows with the FAT32 option and fast formatting disabled;

- I put the .bio file on the flash drive (GK0069.bio);

- I removed the jumper from the bios. Note: It has 3 pins, using the first and the second, accesses directly in the bios, using the second and the third, initializes the windows and in this case I am removing the jumper.

- Turn on NUC;

But it did not work. What can I be doing wrong?

NUC Model: DC3217BY

[n_scott_pearson]

Power off and remove the flash drive. Press and hold the power button for a 1001, 1002, 1003 count and then release. Within about 10-15 seconds, the Power Button Menu should appear. Pressing F2 should then get you into BIOS Setup -- and, if the USB hardware is working, you'll get there with working keyboard and mouse.

I hope that worked. First of all, since this was from the initial generation of NUCs (with 3rd gen Core or equivalent processor), it might not have had support for Power Button Menu (and I don't have one this old to try this myself). Secondly, even if it does, I am suspicious and your USB hardware might being dead. We'll see...

Hi Scott,

Probably there is no support for Power Button Menu in this NUC. In the TPS at least the Power Button Menu is not mentioned.

Leon

[n_scott_pearson]

Yea, that's what I was afraid of. I am remote, working on my phone, so couldn't look it up.
Other thing to try is moving the yellow jumper from pins 1-2 to pins 2-3.

[LeonWaksman]

Pins 2-3 (Maintenance Menu) was my advice yesterday. In this menu the keyboard is not working  neither (could be bad keyboard?)
