In case it is in a standby state that won't wake, press and hold the power button until it powers off. Otherwise:
The pattern of blinking is significant. Identify the pattern and check the reference here to see what error it indicates.
Dell OptiPlex 3020–Mini Tower Owner's Manual > Troubleshooting Your Computer > Power LED Diagnostics
Power LED Diagnostics
Amber LED blinking scheme – The pattern is 2 or 3 blinks followed by a short pause then x number of blinks up to 7. The repeated pattern has a long pause inserted in the middle. For example 2,3 = 2 amber blinks, short pause, 3 amber blinks followed by long pause then repeats.
