DV8210us Won't Start - 4 beeps

[sal1107]

I have a HP Pavilion DV8210us.  I press the power button.  The buttons light up.  The screen is blank.  I hear 4 steady beeps.  The system is out-of-warranty so HP was of no help.  Any assistance would be appreciated!

Try both of the following

1)  Does the notebook sound as if i is running?

If so, in a darkened room shine a flashlight on the display to see if the desktop is dimly visible.

If not, report that in your thread and  then try the following.

2) Try a hard reset.

remove the battery and the DC external power plug.

Press and hold the power button for more than fifteen seconds.

plug in the DC external power  (leave the battery off for now)

press the power button. If it powers up install the battery. It doesn't matter if the laptop is booted into Windows with the power adapter plugged in.

Please post your resuls here

Best regards,

Thanks for getting back to me!

1)The notebook makes a brief humming sound when I first turn it on - otherwise there are no signs of life beyond the lights above the keyboard.  I shone the flashlight on the screen - no signs of life there either.

2)I tried the hard reset - no change.

Remove the hard disk and power it on to see if the BIOS says anything.

A failed hard drive can manifest itself in a no start as well.

4 beeps usually means video failure. That was why I suggested the darkened room  and flashlight test.

I removed the hard drive and restarted the system - no change - the lights turn on, it hums for a few moments, and it beeps 4 times (nothing on the screen).

try removing a memory module (the upper one)and pressing start  for a test. If it boots up...Great. If not test the other stick in the same way.

That did it!  A bad memory module.  I replaced it and it fires up like a champ.

Thanks for all of the help!
