Hi,
I have just attempted an update from BIOS version 3.22 to version 3.24 on a standalone FW13 motherboard inside the Cooler Master case (hence, no battery), and now the system doesn’t power any of the USB peripherals, does not send any signal, ramps the fan to 100%, and, after a good minute or two, shuts itself down.
The exact steps I have followed (this just happened, I will be as factual and thorough as possible):
- Enabled Standalone operation in the bios, cleared TPM, reset CA to factory, updated bios date (since it was in january of 2001, perhaps indicative of a BIOS battery issue?), disabled secure boot
- Formatted a USB key to FAT32 from my desktop, before I decompressed the “BIOS 3.24 (EFI Shell update)” archive obtained from the
knowledgebase - Plugged my devices in the following manner :
- Power on the lower-left port (the charger is a 100W PD UGreen Nexode)
- Display (HDMI framework expansion slot) on the upper-left port
- USB key on the lower-right port
- keyboard on upper-right port
- Booted on the USB key from the F12 boot menu
- Waited until the green progress bar with the framework logo completed
- The system seemed to have rebooted, then had 100% fan speed, no power to the keyboard or even the USB key (its LED light remained completely off)
- Waited for a while (hard to say how long, probably 8-10 minutes)
- Tried to force shutdown by pressing then maintaining the power button
- Device did not shut down
- After an additional 5 minute, decided to unplug the system
- Unplugged everything for more than 90 seconds (as instructed in the
knowledgebase) before reattempting - Tried restarting with USB key and keyboard ports swapped
- Tried restarting without the USB key plugged into the system
With the above all of the above done, symptoms remain the same:
- No display signal
- Fan ramp up to 100%
- Keyboard does not light up as expected
- After some time, the system shuts itself down
Additional informations :
- I did not have a lithium ion battery connected to this system during the BIOS flash (I did not see the “This update requires a battery present to complete the update.” line in the documentation before attempting the BIOS update)
- NVMe and RAM are known to be at the very least in a kinda working state since I have installed linux mint on this system without much issue
- Outside of the initial green progress bar, I did not get any of the instruction screens talked about and screenshoted into the knowledgebase guide
What are your opinions? What can be done?
PS: See this post for my rant about the knowledgebase documentation
