Intermittent display flicker

[Sh93]

I'm experiencing display brightness flickering from time to time. It usually have to increase the brightness to fix this temporarily. This has been there for a while. My current BIOS is F.61. Serial number:8CG64918MX, Product number:W0U47AV.

Display flickering is nearly always a sign of the screen failing.

You need to connect an external monitor to the laptop.

If the visual artifacts also appear on the monitor, then it is a failing video chip and since those are soldered to the motherboard, they are not replaceable.

If the visual artifacts do NOT appear on the monitor, then it is a failing laptop screen. While those can be replaced, the cost varies enormously by individual PC model.

For this information, you would need to contact an HP Repair or Service Center.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
