Coil Whine Noise on intial turning on of laptop

[AreenKolekar]

Its been less than a week purchasing my laptop, after 4 days while turning on I'am hearing an screeching or coil whine noise from laptop while turning it on for first 13 seconds and NOTE: this noise come only when keyboard light is on during turning on pc. But if the keyboard light is off while turning on laptop, the sound is absent. Is it an serious issue or common?

Updating the BIOS is recommended as standard maintenance of the computer. It can also help resolve the following issues:

• An available BIOS update resolves a specific issue or improves computer performance.
• The current BIOS does not support a hardware component or a Windows upgrade.
• HP Support recommends installing a specific BIOS update.

(2) Reboot

(3) Let BIOS be installed until it's completely done !

(4) Test your hardware Using the HP PC Hardware Diagnostics (UEFI)

Answer: This is serious issue

HP warranty valid -> Contact HP Support

HP warranty expired ->

You should have it serviced by a professional notebook (chip level) repair store.
