Unable to boot even to BIOS

HP Recommended
HP 15 - AY503TX
Microsoft Windows 10 (64-bit)

I am unable to boot the system, there are no beep sound and only indication that system power up is CAPS key keep blinking every 4 seconds and Screen remains black, there are no other indications. 

I have tried to Reset BIOS using Windows+ B/V on Power, tried to reset CMOS by removing CMOS battery but nothing works.

To Check if any other part is causing the issue, i have removed ram, hard disk  and other component, but issue still stay as before. 

Tried removing battery  and power up only on AC but no effects. Tried every permutation and combination of above steps.

 

would any of you be able to provide insight into this issue?

@NKPY 

I don't know why everyone removes the CMOS battery as in a laptop, that is a waste of time!

 

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
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:

https://support.hp.com/us-en/contact-hp?openCLC=true

If you can't get assistance from HP, then you will have to seek out a local laptop service facility to have them examine it for you.

Good Luck

I got it diagnosed and looks like the motherboard is dead.

And they said the wont be able able to replace it as they don't have inventory for this model.

 

As far as i know motherboard would cost around 40% price of laptop in aftermarket.

 

Whats the best thing to do in this scenario??

And if it can't be repaired whats the best thing to do with the dead laptop?
