Laptop on but no screen and caps lock blinking

[Ram56]

My laptop is on but no screen and caps lock  nonstop blinking every 3-4 second Wi-Fi light is Red.

@Ram56 Note that specific patterns of long and short blinks along with long and short beeps (where applicable) identify errors during the startup process.
Newer computers have two-part blink sequences with different color lights to indicate specific errors and you may click here and troubleshoot on your own or get back to me with the precise sequence for apt steps to help identify and fix the issue.

Wi-Fi light not blinking only red no beeping sounds

@Ram56 What about the capslock blinking you've mentioned earlier? what sequence does it blink in? did you happen to check?

[Ram56]

Yes I have checked that the caps lock blinks once in 4 seconds in sequence and the Wi-Fi light is Red without blink.The laptop does not have beeping sound.

@Ram56 That sequence of blinks represents a Graphics controller not functional error and I suggest you talk to HP support and discuss your options, follow the below steps to get started:

Fill the web-form, to populate a case number and phone number for yourself!

Also, 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,
