M900x & Tiny: Recover from failed BIOS update (CMOS jumper, recovery)

2016-12-14, 0:09 AM

Hi, 

I have a problem, after a BIOS update the machine does not start. On power up, light indicator is green but nothing is displayed on the monitor.

This happened in the procedure described here: https://download.lenovo.com/pccbbs/thinkcentre_bios/fwjy5fusa.txt
on Step 6, after the reboot.
How can I address this problem? Is there any way to reset the BIOS to previous state?

 

Thanks!

 

Mod:  edited Subject line to define which M900 model and clarify the problem description

These are the steps:

  1. Burn the latest Firmware (fwj963usa.iso) to a CD
  2. Power down, disconnect all cables.
  3. Open the case and remove the case for the 2,5" drive
  4. Set the jumper from Pin 4/6 to 2/4, see attachment
  5. Add the case for the 2,5" drive and close the case
  6. Connect a external CD Drive with the CD to any USB Port
  7. Connect the monitor and the power cable
  8. Now the M900 will power up and after a short time you can hear that the CD Drive is accessing the data
  9. After this you will see that the BIOS menu is visible on your screen and the update proceed
  10. After this the M900 power down
  11. Open the case and set the Jumper back to Pin 4/6, see attachment
  12. Close the case connect all device
  13. Power on and enjoy your operating system

In the hardware maintenance manual for your specific model of M900, there will be a section on how to recover from a BIOS update failure.

So, for my model, the M900x (tiny form factor), the hardware maintenance manual includes a section titled "Updating and recovering the BIOS" but on that page it has no recovery info, only a "Updating the BIOS" section. 

In contrast, the M900 (tower form factor) hardware maintenance maual has a recovery section that outlines a solution involving setting some jumpers. 

I really do hope the M900x is a bit more advanced and can recover without setting jumpers. I will try tonight to update using the cd iso method.

Hi, I have the same problem. After Updating the BIOS with the Lenovo Companion it doesn't boot anymore.

Did you find a solution?

 

What does not help:

- Remove the BIOS battery, wait some minutes. Insert it and boot

 

It's a customers Workstation and I'm not able to get any support member on the phone :-(

The device was bought two month ago and is now broken. I though Lenovo would build more stable Hardware and Software, especially for such a expensive device.

 

EDIT: The M900 gives two short beeps

Can you create a bootable flash drive using the 'CD ISO' file (file name ends in .iso) from BIOS page here.   Then boot from it and run the stand-alone installer (when it asks if you want to change the model and/or serial number, reply no unless you're replaced the motherboard.)

So, in my case I had the motherboard replaced by a tech support guy. I called a number that I found on the site where I purchased the pc and had an appointement made for the next day, on site. Half an hour work, all went fine.

 

Before that, I tried to flash the pc using the ISO image on a cd-rom. I managed to succeed the re-flashing operation but the pc again wouldn't start. If you try that, you need to open up the case and set a jumper correctly. The hardware maintenance manual for M900x is missing this piece of info (look in the hardware maintenance manual of M900 for details, the location of the jumper is in the front, about 1cm away behind the speaker).
