Black screen

[Eh_8482]

Hello, I cannot get my laptop to boot into safe mode. I have done a hard reset and probably all the trouble shoots on here and nothing is working. Computer turns on I believe because the lights come on I can hear the fan but screen stays black! Also the “caps locks” button does 3 white long flashes in a row and then 2 white fast ones ? Any advice would be greatly appreciated.

Hi @ Eh_8482,

Welcome to the HP Support Community.

Thank you for posting your query. I will be glad to help you.

I Understand that your laptop has laptop is giving a diagnostic blink code, and the pattern you described 3 long white flashes + 2 short white flashes on the Caps Lock is almost certainly an HP laptop error code, Kindly try the below steps. 
 

 1. Hard Reset (real one)

1. Turn laptop completely off
2. Unplug charger
3. Remove the battery if it is removable
4. Hold power button for 20–30 seconds
5. Reconnect the charger only → try to power on

2. Reseat or swap the RAM

A very common cause of black screens and blink codes.

1. Turn laptop off
2. Remove AC
3. Open the RAM cover (if accessible)
4. Remove each RAM module
5. Clean gold contacts with a dry microfiber cloth
6. Reinsert one stick at a time → test booting

If one stick works and the other doesn’t the ram stick could be faulty. 

3. Try an external monitor

If external display works, your internal screen or cable may be bad.

• Connect HDMI to a TV or monitor
• Turn laptop on
• Press Win + P several times (or wait 10–20 seconds)

4. BIOS Recovery (HP)

1. Turn laptop off
2. Hold Windows key + B
3. While holding, press Power for 1 second
4. Continue holding Win + B for 5–10 seconds

This triggers BIOS auto-recovery.

I hope this helps.
