Why does everything work in 45 degrees, but when fully open screen is frozen?

The problem you’re facing might be due to a hardware glitch involving either the hinge assembly or the display ribbon cable itself. Stress and strain when opening the screen fully could cause breakages or disruptions in the signal.

Steps to address it might include:
1. External Display Test: Plug your laptop into an external monitor to check if the laptop operates without freezing. If the external monitor works fine, this points directly to a screen connection issue inside the laptop.
2. Driver Verification: While less likely, outdated graphics drivers can sometimes create unusual hardware issues. Make sure your laptop’s drivers are up-to-date.
3. Professional Diagnosis: If you’re not confident about opening up your laptop, a certified technician should be able to diagnose and fix the issue. Explaining that the problem occurs when fully opening the screen can save them time in locating the fault.

Using these varied methods will enhance your understanding of the issue and ensure accurate troubleshooting.

I’m pretty sure the issue you’re experiencing is due to a malfunctioning flex cable inside your laptop. When the screen is partially open, the cable isn’t under stress, but as you fully open it, the cable might be stretching or getting pinched, which leads to the screen freezing.

To confirm and fix this issue, you could:
1. Carefully open the laptop’s casing.
2. Inspect the flex cable for any visible damage or signs of wear.
3. If you’re comfortable with it, try repositioning the cable to see if that alters the behavior.
4. If the cable appears damaged, you may need to replace it, which might require a visit to a professional or ordering a specific part.

This problem isn’t uncommon, and it’s often related to the physical state of the internal components as they age or get worn through regular use.

Your issue sounds like a classic example of a hardware malfunction, primarily involving the hinge assembly or internal wiring. When the laptop is partly open, all connections are intact, but opening it fully might strain or disrupt those connections. This could include the video cable or even connections on the motherboard.

1. First, test if the problem persists when using an external monitor. If the external display works fine when the laptop screen freezes, your issue is definitely with the laptop’s internal display connections.
2. Sometimes, merely updating the graphics drivers or the laptop’s BIOS can resolve such quirky issues. Therefore, check the manufacturer’s website for any updates.
3. If you’re not comfortable opening your laptop, a professional technician’s services might be required. They’ll check the hinges, cable placements, and possibly re-solder any loose connections.

This situation reminds me of a similar problem I had with my laptop. The symptoms suggest a potential internal hardware issue, likely within the hinge mechanism. As you open the laptop fully, the stress on the cables inside the hinge might be causing the freeze.

Here’s what you could try:
– Testing Different Positions: Try opening your screen at incremental angles (e.g., 60 degrees, 75 degrees) to see if there’s a specific point where freezing begins. This can help identify precisely when the problem occurs.
– Driver Updates: Ensure all your drivers, especially the graphics driver, are up-to-date. Occasionally, driver issues can create odd hardware problems.
– Contact Support: If your laptop is still under warranty, I strongly recommend contacting customer support. Explain the problem in detail; they might offer free repair or troubleshooting advice.

I’ve dealt with this exact issue, and in my case, the culprit was a broken hinge that slowly tore the display cable each time I fully opened the laptop. This manifested as a frozen screen.

Here’s how I handled it:
1. Visual Inspection: I carefully checked the hinges and surrounding areas for any signs of wear or damage.
2. Disassembly and Check: Opened up the laptop (following an online guide) to inspect the display cable. I noticed fraying where the hinge bent the cable.
3. Replacing the Cable: Ordered a replacement display cable specific to my laptop model and replaced the damaged one. This completely resolved the freezing issue.

I felt it was a cost-effective solution, though it required precision and took some time.
