Yes, if the computer is sleep or standby mode it is normal for the power light LED to flash, or blink. This lets you know the computer is still on, and that it's in a power-saving mode. If your computer is in this mode, press any keyboard key or button on a mouse to exit power saving mode.

Hard drive light

Many computers also have a hard drive indicator that flash each time the computer hard drive has data read from or written to the drive. This light flashes often or stay on solid for a few seconds frequently as you work on the computer. This too is completely normal.
