This behavior could be related to a corruption during the Flash BIOS update process. Here are our recommendations for this issue:
1. Remove the RTC (Real Time Clock) battery and leave it out for 20 minutes. After this period of time, insert the battery back in and turn the system back on; if it displays POST messages, go into BIOS Setup Utility by pressing <F2> during the boot process. Once in the BIOS setup utility, press <F9> to restore BIOS default settings. Reset any customized BIOS settings. Clear all DMI event logs, which are located in the Advanced/Event Log Configuration section of the BIOS Setup utility. Press <F10> to save the new settings and reboot the system.
2. Proceed with a BIOS recovery test.
