Perform a hard reset on the Notebook. To perform a hard reset, follow the steps below.

• Unplug the AC adapter from the notebook PC.
• Remove the battery from the notebook battery compartment.
• Disconnect any external devices or peripherals connected to the notebook. Press and hold down the power button for about 15 seconds

If hard reset does not work, it could most possibly be a hardware failure and Please verify blink code sequence at below link

First of all, thank you for your post, was really helpfull. After examinating the blinks it appears to be a problem with my CPU. Does that mean I might have to replace it? What is your advice?

Hello, i have same kind of problem but my leds just keep on blinking after 6 blinks... and it does it even when I take the memory modules off. My guess is that the motherboard i broken.

Do those blink error codes apply to the dv5-2077cl laptop?  I replaced my CPU but am still getting the single blink error code..
