HP Pavilion Laptop not booting

[Rasher77]

Hi,  Im trying to repair a laptop for my elderly neighour.  I have some knowledge of IT repair so not a complete novice.   The laptop sounds 3 sets of 3 long beeps then stops.  Screen blank and Caps lock blinks 3 long blinks then pauses and continues in that cycle.    I tried removing RAM and fitting new 4Gb Stick with no success.   I can hear the fan etc and the power light is steady white at the side.   Any further help would be appreciated.   Thanks

Then ... you should know that beeps and/or blinks are indications of hardware failures.

If the CapsLock key is blinking or there is beeping, read this HP information on the likely cause of the hardware failure based on the blinking or beeping patters.

For laptops, this HP thread describes the different blink and beep codes: https://support.hp.com/us-en/document/c01732674?jumpid=reg_r1002_usen_c-001_title_r0001
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

Here is how you can get in touch with support:
Step 1. Here is the link: http://www.hp.com/contacthp/
Step 2. Select the product type.
Step 3. Enter the serial number of your device or select let HP detect your product option.
Step 4. Select the country from the drop-down.
Step 5. You should see the HP phone support number or Chat option listed.

--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

If you don't get useful results using the Service Center link, here is the main HP link:

Hi WaWood,  Many thanks for the detailed reply.   Yes, I already checked the codes and iys saying its says the following: 

' The embedded controller times out waiting for BIOS to return from graphics initialization or if a graphics output device failed to initialize' .   

The Laptop wont boot into bios etc.  I took it apart myself and had only the motherboard, ssd drive and screen connected, so I believe its a motherboard at fault.  Lots of these being sold as faulty on ebay isn't a reassuring sign.   I think its for the recycling pile.   Cheers
