If your HP EliteBook 840 G4 hangs a few minutes after startup, even after changing the RAM and hard disk, the issue is likely related to overheating, power delivery, BIOS settings, or a motherboard failure. Here are some things to check: 1. Check for Overheating Issues If the laptop gets hot quickly before freezing, it might be a thermal issue. Try entering the BIOS (press F10 at startup) and check if it still hangs. If it does, it's likely hardware-related. Clean the cooling fan and heatsink and reapply thermal paste to the CPU. Run a hardware diagnostic (press F2 at startup and select "System Diagnostics"). --- 2. Run in Safe Mode (Check for Software Issues) If the issue happens only in Windows, try booting in Safe Mode: 1. Restart and press F8 or Shift + F8 repeatedly before Windows loads. 2. Select Safe Mode and see if the laptop still hangs. 3. If it works fine in Safe Mode, the problem might be a driver conflict or malware. 3. Update BIOS & Drivers If the BIOS is outdated, update it from the HP...

Here are some troubleshooting steps to try: 1. Basic Power Reset (EC Reset) – Try This First! Since your laptop drained completely, it may need an EC (Embedded Controller) reset: 1. Unplug the charger and disconnect any peripherals (USB, external monitor, etc.). 2. Press and hold the power button for 30-60 seconds. 3. Release the button, then plug in the charger and wait 10-15 minutes before trying to turn it on again. 2. Check the Charger & Charging Port Try a different outlet to rule out power issues. If possible, test with another compatible charger (ROG laptops are sensitive to power supply quality). Inspect the charging port for dust or damage—sometimes, debris prevents proper contact. 3. Check for Battery or Power Delivery Issues When you plug in the charger, does the charging light stay on? If yes, but the laptop won’t turn on, it could be a battery issue. If the light turns off again, there might be a short circuit or power delivery problem. Try turning it on without the battery (if removable) by...

Here are a few possible fixes: 1. Check the Batteries The X-370 has an electronically controlled shutter, meaning dead or weak batteries can cause the shutter to stop working. Try replacing the two SR44, LR44, or equivalent 1.5V batteries and see if that helps. 2. Reset the Mirror & Shutter Since the mirror flips up but doesn’t come down normally, the shutter may be stuck. Try this: 1. Remove the lens to see the mirror. 2. If the mirror is up, gently press it down with a soft tool (like a cotton swab). 3. Once the mirror is down, try pressing the shutter button again. 3. Engage and Disengage the Self-Timer Sometimes, the self-timer gets stuck and prevents the shutter from firing. If your camera’s self-timer is engaged: 1. Wind it up and let it fully run down. 2. Then try pressing the shutter button. 4. Check the Film Advance Lever If the lever moves but doesn’t engage the shutter, the internal mechanics may be misaligned. Try slowly advancing the lever and pressing the shutter at different points to see if...
