Tech Fix Daily

Is your HP laptop refusing to wake up? Whether it’s completely dead or just stuck on a black screen, this guide walks you through every fix—from quick resets to deep hardware checks.

🔌 Step 1: Try a Hard Reset

• Disconnect the AC adapter and remove the battery (if removable).
• Press and hold the power button for 15–20 seconds to discharge residual power.
• Reconnect the AC adapter (without battery) and try powering on.

💡 Why it works: Clears temporary configurations that may block startup.

🔍 Step 2: Check Power Connections

• Inspect the AC adapter for damage, loose plugs, or frayed wires.
• Confirm the LED on the adapter brick is lit.
• Try a different wall outlet or adapter if available.

🔌 Tip: Use only the official HP adapter to avoid voltage mismatch.

🔋 Step 3: Test the Battery

• Removable battery: Remove and inspect for swelling or corrosion.
• Try powering on with just the AC adapter.
• Non-removable battery: Hold the power button for 15 seconds with adapter unplugged, then reconnect and charge for 30 minutes.

⚠️ If it turns on without the battery, the battery may need replacement.

🧪 Step 4: Run HP Diagnostics

• If the laptop powers on but won’t boot, press F2 repeatedly after powering on to enter diagnostics.
• Run the AC Adapter Test and Battery Test under “Component Tests → Power.”

🧠 These tests check voltage, battery health, and charging circuitry.

🧠 Step 5: Check for Display Issues

• Listen for fan noise or LED indicators.
• Connect to an external monitor to rule out screen failure.
• If external display works, the issue is likely with the built-in screen.

🧱 Step 6: Inspect RAM and Internal Components

• Open the back panel and reseat RAM modules.
• Try booting with one RAM stick at a time.
• Check for signs of damage on the motherboard or charging port.

🧰 Faulty RAM or loose connectors can prevent booting entirely.

🔄 Step 7: Reset BIOS Settings

• Power on and press F10 to enter BIOS.
• Restore default settings and save changes.
• If BIOS won’t load, try removing and reinserting the CMOS battery.

🧼 Step 8: Clean and Cool

• Check for overheating or blocked vents.
• Use compressed air to clean dust from fans and heatsinks.
• Let the laptop cool down before retrying.

🧯 Step 9: Final Checks

• Look for blinking power LEDs (may indicate hardware failure).
• If no signs of life at all, motherboard or power switch may be faulty.
• Consider professional repair if all steps fail.
