🖥️ HP ProBook Showing a Black Screen? Here’s What Might Be Causing It — and How We Can Fix It

Power on, fan running — but the screen stays completely black? If your HP ProBook laptop is showing a blank or black screen, you’re not alone. This is a common issue that can stem from several causes — and in most cases, it’s fixable.

At Gary’s Computer Repair Service, we specialize in diagnosing and repairing HP ProBook display issues so you can get back to work without delay.

🔍 Common Causes of the HP ProBook Black Screen Issue

1️⃣ Display Brightness or Sleep Mode Glitch
Sometimes the system is running, but the display is too dim or stuck in a suspended state.

2️⃣ Loose Display Cable or Faulty LCD Panel
A loose internal connector or a damaged screen panel can prevent visuals from showing.

3️⃣ Graphics Driver or BIOS Error
A corrupted driver or outdated BIOS can cause startup conflicts, leaving the screen blank.

4️⃣ RAM or Power Supply Issues
Faulty RAM can prevent the laptop from booting fully, while charging issues can mimic display failure.

5️⃣ Backlight Failure
The display may technically work — but if the backlight is dead, the screen will appear completely black.
