black screen

[sgtmom82990]

This is a friend's laptop so I don't know much about it.  When I hit the power on button I can hear that the machine is on, but the screen remains black without any indication of it being on.  I've connected it to an external (working) monitor & nothing shows on that either.  I've taken the battery out & done a "hard" reset...to no avail.  I checked to make sure the hard drive & RAM were securely seated.  Where do I go from here?

Hi

It seems to be hardware issue,

Please call HP tech support if the unit is under warranty we will repair the unit,

If the unit is not under warranty, please contact local HP service center

It's not my machine & I can only assume I'll have to pay the "Tech team".  I'm looking at it because she can't afford to pay anything.  I know some stuff about computers, this one stumps me.  I can't look at anything until the screen is working... but thanks anyway.

As Sree_Here mentioned, if still within warranty, call your HP in your area/country, do not try to repair it yourself.

If it is out of warranty, as you said, there is no display, but can you hear any indication of anything moving such as the fan spinning? Are there any LED or power lights displayed?

I do hear that it is on. The on button in the front, along the edge is on. The caps light & the number lock light both are blinking white.  The wireless light is amber & steady.  The touch pad light is white & steady. I appreciate your help. Thank you!

OK, try this.

Disconnect the power.

Remove the battery.

Remove the ram modules. If you have two modules, remove and reseat only one.

Connect power and try again.

If it does not work, swap the ram modules, otherwise if working, you have a faulty ram module.

I know you have removed and reseated the ram modules, but just make sure they CLICK in firmly and connect.

Please advise me on yoru progress in order for me to assist further.

Alright I removed each ram module individually & nothing has changed. I did, however, notice that as I plug in & unplug the external monitor, the monitor itself is powering into & out of "power save mode".  So that tells me it IS picking up a signal of sorts, from this machine.
