Why my laptop keyboard it not working and when I on it it starts beepi?

From what you have described, it seems that your laptop may be having issues related to the system firmware or internal components. Beeping usually indicates a hardware error detected during the Power-On Self Test (POST). Consider the following steps:
1. Reconnect the Keyboard: Carefully open your laptop and reseat the keyboard connector. Sometimes, it gets loose, causing malfunction.
2. Update BIOS: An outdated BIOS can occasionally result in hardware compatibility issues. Get the latest version from your laptop manufacturer’s website.

The issue with your laptop beeping continuously upon startup, and the non-responsive keyboard, typically signifies that there might be a critical error detected at boot. Here’s how to proceed:
1. Motherboard Diagnosis: The keyboard controller on the motherboard might be failing. If possible, consult a professional technician to run diagnostics on your motherboard.
2. Detailed Check-up in Safe Mode/BIOS: If you can access the BIOS settings, check if the keyboard works there. If it does, then the problem might lie with the operating system. Entering Safe Mode can also help diagnose driver issues.

It appears that you have a hardware issue. When your laptop beeps at startup, it’s often a BIOS (Basic Input/Output System) signal indicating a specific error. The sequence of the beeps can help you identify the problem:
1. Refer to the Manual: Check the user manual of your laptop or the manufacturer’s website for the beep code meanings.
2. Internal Hardware Check: The problem might be related to a loose or faulty internal connection with the keyboard. If you’re comfortable with it, you can open the laptop and check the internal keyboard connector.

It sounds like your laptop’s issue relates to the keyboard matrix which could trigger key errors and beep codes indicating a hardware fault. Here’s an approach you can take:
1. Inspect the Physical Keyboard: Analyze if liquid spill or heavy use could have damaged the keys.
2. BIOS Beep Codes Interpretation: Different laptops use different beep codes. Refer to your laptop’s documentation or check online resources to decode what the sequence of beeps is indicating.

To address why your laptop keyboard is not working and the beeping issue when you turn it on, I’ll give you a few steps to diagnose the situation. First, check if any keys are stuck or physically jammed because this could trigger both the non-functioning keyboard and continuous beeping. Here’s what you can try:
1. Power Cycle: Shut down your laptop completely. Unplug it and remove the battery (if possible). Hold down the power button for about 30 seconds. Reattach the battery and power it back on.
2. Check for Dust/Debris: Sometimes, dirt can get stuck under the keys. Use a can of compressed air to blow out any loose debris.
3. Boot into Safe Mode: Try booting your laptop in Safe Mode. If it works there, it might be a software or driver issue.

Experiencing an unresponsive keyboard paired with beeping noises can be very inconvenient. The beeping sound is often a way for your laptop to communicate that something isn’t right at a deeper hardware level. Here’s what you can do:
1. Check Sticky Keys: Sometimes, a key might be held down because something is physically pressing it. Inspect and ensure all keys are standing properly.
2. External Keyboard Try-Out: Plug an external USB keyboard into your laptop to test if the issue persists. If the external keyboard works fine, this minimizes the possibility of a software issue.
