System fails to wake from sleep, just a 2-3 sec beep?

Ever since updating to the latest bios(recommended for windows 10) my system doesn't wake from sleep mode, just a solid power light and a beep that's last 2-3 seconds. I'll hold the power button to turn it off, than press power again to turn it, bios post as normal, than windows loads and resumes to wake from sleep mode as if power was lost while sleeping. The only work around is to disable sleep mode. BTW, my system is a Aspire TC-605.
