TS150 bios recovery with CD-ROM

2018-08-19, 6:20 AM

During the bios update procedure, power line was accidentaly pulled off.

After I plug in power cable again, system was turned on but without any post screen.

I think the bios must have been corrupted.

After pushing power button a few seconds, system turned off but still system fans are rotating in very low speed.

With power button on, system seems to be turned on with power LED on and elevated fan speed but no post screen.

There is no beep at all.

I tried bios recovery procedure with bootable USB thumb drive several times, but nothing changed.

Still I can not see post screen.

Is there any other way to do a bios recovery procedure, for example via CD-ROM?

There seems no IMG or CD-ROM image for bios recovery.

Should I replace the motherboard?

Thank you in advance.

HMM pages 22 and 23 describe recovery from Bios Update failure.

https://download.lenovo.com/pccbbs/thinkservers/ts150ughmm_en.pdf

 

Boot Block Recovery:

Shut down machine.

Move Cmos jumper from pin 1-2 to 2-3 (maintenance position).

Boot machine with BIOS update on  USB stick.  It will reflash. Shutdown machine.

Move Cmos jumper back to pin 1-2 position.  

 

Note:This jumper is extremely small. Use tweezers and avoid being near A/C vents, etc.

 

I would double check the README.txt for BIOS on your support page and ensure USB stick was created correctly.

Thank you for your reply.

I followed the instruction by using Rufus version 2.2 and made MS-DOS bootable usb disc, but failed.

Nothing changes.

Hello ophtha72, just to be clear did you run through the BIOS recovery procedure by moving the jumper as well as trying to flash the BIOS again? 

 

Recover BIOS settings from a BIOS update failure

To recover BIOS settings from a BIOS update failure, do the following:

1. Prepare your server. See “Preparing your server and removing the server cover” on page 41.

2. Locate the Clear CMOS jumper on the system board. Then, remove any parts and disconnect any cables that might impede your access to the jumper. Note: Do not remove the memory modules or CPU.

3. Move the Clear CMOS jumper cap from the default position (pins 1–2) to the short-circuited position (pins 2–3).

4. Reinstall any parts and reconnect any cables. Then, reinstall the server cover. See “Completing the parts replacement” on page 96.

5. Reconnect the server to an ac power and turn on the server. Then, insert the BIOS update (flash update) disc into the optical drive. The recovery session begins. The recovery session will take two to three minutes. During this time, you will hear a series of beeps.

6. After the recovery session is completed, the series of beeps will end, and the system will automatically turn off. Remove the disc from the optical drive before the system completely turns off.

7. Repeat steps 1 and 2.

8. Move the Clear CMOS jumper cap back to the default position.
