It sounds frustrating, but here are a few things you can try to fix the issue with your HP Officejet 4620:

1. Check for Clogs – The ink cartridge could be clogged. Run the printer's cleaning cycle (usually found in the printer settings under "Tools" or "Maintenance"). This will help clear any blockages in the printhead.
2. Reinstall the Cartridge – Sometimes the cartridge doesn’t seat correctly. Remove the black ink cartridge, then reinstall it firmly to ensure it’s properly in place.
3. Printhead Cleaning – If the automatic cleaning doesn’t work, you can manually clean the printhead. Gently wipe the printhead area with a soft, lint-free cloth moistened with warm water.
4. Check Cartridge Chips – The cartridge might have a faulty chip, which can prevent it from communicating with the printer. Try using a different black ink cartridge to see if that resolves the issue.
5. Check for Software/Driver Issues – Sometimes, the problem could be related to your printer’s software or drivers. Ensure you have the latest printer drivers installed, or try uninstalling and reinstalling them.
6. Align the Cartridges – In the printer settings, there’s an option to align the printheads. Running an alignment might help fix printing issues.

If none of these work, there could be a more serious issue with the printer’s printhead, and you might need to contact HP support for further assistance or consider servicing the printer.

It sounds like the flash mechanism might be stuck or the spring inside isn't working properly. Here’s what you can try:

1. Check for Obstructions – Sometimes dust or dirt can prevent the flash from popping up. Gently clean around the flash area with a soft brush.
2. Manual Pop-Up – Try to gently pull the flash up with your fingers (if it's safe to do so). Don't force it too much; just a little help might get it working.
3. Reset the Camera – Turn your camera off and then on again. This can sometimes reset the mechanism.
4. Check for Firmware Updates – Occasionally, software issues can cause this problem. Check if your camera has a firmware update available.

If none of this works, there might be an internal issue with the mechanism, and you may need to have it serviced.

This issue usually happens due to a mismatch between the actual screen brightness and what your system thinks the brightness is. Here are some common reasons and quick fixes:

1. Adaptive Brightness is Enabled – Windows might auto-adjust brightness based on lighting.
2. Display Driver Glitch – The driver may not be syncing brightness settings correctly.
3. Power Plan Conflicts – Your power mode may be overriding manual settings.
4. Outdated/Corrupt Display Driver – Can cause incorrect brightness reporting.
5. Third-party software interference – Some apps adjust brightness automatically (like f.lux or manufacturer tools).

===

• Go to: Settings > System > Display > Brightness
• Disable: "Change brightness automatically when lighting changes"

• Press Win + X > Device Manager > Display Adapters
• Right-click your GPU > Update Driver
• Or uninstall and restart to reinstall it automatically.

• Control Panel > Power Options
• Choose Balanced or High Performance and adjust brightness there.

• If you're on a desktop, physical buttons may override OS brightness.

Resetting a BIOS password depends on the computer/motherboard. Here are common methods:

• Turn off the PC and unplug it.
• Open the case and locate the CMOS battery (a small silver coin cell).
• Remove it for 5–10 minutes, then reinsert it.
• This often resets BIOS settings, including the password.

• Find the CLEAR CMOS jumper on the motherboard.
• Move the jumper from pins 1–2 to 2–3 for a few seconds, then move it back.
• Power on the system—BIOS should reset.

• Some BIOS setups accept default passwords (like for Dell, HP, etc.).
• You can search “[Your brand] BIOS backdoor password” online.

• Tools like CMOS De-Animator or Hiren’s Boot CD can reset BIOS passwords on older systems.

⚠️ Note: These methods may void your warranty or damage the device if done incorrectly. If unsure, contact the device’s support.

No, it's not normal for an SSD card to look messy with PCB parts not properly attached. This suggests that the SSD might have been damaged or tampered with. It's crucial for the SSD to be intact and properly connected for the Xbox Series S to function correctly. If you bought this console recently and it's not starting, it might be best to return it or get a refund, especially if the SSD card looks damaged.

I would compare the connector pinout to see if they match electrically within the schematics before trying.
