Capslock LED blinks 3 long and 5 short

[saikrishna289]

Laptop Details:

Model number: HP Envy x360 15m-cn0012dx

OS: Windows 11 Home 64-bit

Country of Purchase: United States

Year of Purchase: 2018

Problem:

Laptop doesn’t boot. Nothing shows on screen. When I power on, LED on power button blinks 5 times long and then Caps Lock LED blinks 3 long and 5 short. 

Solutions tried:

Opened laptop back cover, removed battery, plugged in power source and tried restart. Not worked.

Tried removing RAM form each slot and tested. That didn’t work too. Tried to boot to Bios recovery using windows key and B(V) combination with power button. No luck on this too.

Much appreciate your help in this regard. Thanks.

Please try a hard reset and see if it works.

• Power off your laptop,
• Remove the a/c adapter, battery and everything that is attached to your laptop,
• Hold the 'POWER' button down on your laptop for about 10 seconds.
• Plug in the a/c power supply (without battery) and power on.

Regards.

Hi Banhien,

 Thank you for your suggestion. Followed all the steps mentioned but unfortunately Hard Reset didn’t work.

Finally the issue is resolved. Took to local repair shop. He removed the battery, waited for 10 mins, plugged in AC power cable and hit on the power button. Viola!! It started.
