Blank screen - unable to boot into BIOS and no HDMI output

[DarloB]

I bought a HP Pavilion 14-ce3501sa 14" Laptop 18 months ago. Now when I switch it on  the screen flickers but then goes black. I am unable to boot into BIOS and no HDMI output although the fan on the motherboard is working .  I have taken it to an independent computer repairer who has says the problem appears to be with the power supply to the CPU and the only solution is to replace the motherboard which is uneconomic. Surely this should not happen to  an 18 month old laptop?

Hi@DarloB, Welcome to the HP Support Community!

We reviewed your post and I understand that the  Notebook is not Powering ON,

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check if it helps

Do you see a light at the place where the charger connects to the laptop? If yes then it indicates that the charger is all fine.

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.

F6 + Power Button

• CMOS Rest ( combination of windows button and letter 'V' then push the power button ones and release the windows and letter 'V' after 5sec

If the laptop does not power on then please continue with the below steps:

• Disconnect the charger and remove the battery out.
• Connect only the battery and check if the laptop powers on.
• Likewise, remove the battery out (if removal battery ) and connect only the charger and check if that helps.

Hope this helps! Keep me posted.

Unable to unplug the battery. Have sent it back to Currys to repair  who say they think it's a faulty BIOS chip as although there is power to the motherboard there are no beeps at start up. Awaiting  there final report

Hi@DarloB,

As this is a hardware issue, I'd suggest you Contact HP in your region regarding the service options for your computer. 

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.
