Having problems with your HP Compaq Presario C500t Notebook ?

Fast Blinking Power Button

\015 I have a compaq Presarion C500 Model Rz341UA. The computer will not start. It starts the hard drive and immediately stops and the power light starts blinking. This happens with both battery and AC adapter connected. It shutdowns only by pressing the power button for a long period of time.\015

Answers :

Check your RAM. I had the same problem with my C500. I ended up having a bad stick of RAM. The only other cause I know of is the hard drive. Although this is rare if you had no problems with your operating system before.
