my fanless lenovo screen is blurry after heating

Blurry screens after a fanless laptop heats up are a classic sign of overheating, which can stress the integrated graphics and the display’s internal components. A fanless design relies on passive cooling, and if this system is overwhelmed, the heat can cause the display to malfunction. 

How to fix the blurry screen issue

1. Let the laptop cool down

Turn off your laptop immediately and let it sit for 30–60 minutes to cool down completely. If the problem disappears when it’s cool but returns with heat, you know it’s an overheating issue. 

2. Improve ventilation

  • Move to a flat, hard surface: Avoid using your laptop on soft surfaces like beds, blankets, or pillows, which can block the tiny vent holes and trap heat.
  • Elevate the laptop: Use a book or a specialized laptop stand to raise the device and allow air to circulate underneath.
  • Use a cooling pad: For more intensive use, an external laptop cooling pad with built-in fans can significantly improve heat dissipation. 

3. Adjust power and performance settings

Since your laptop has no active fan to control, you can manage performance to generate less heat.

  • Set the power plan to “Power Saver”: In Windows, go to Settings > System > Power & battery. Switching to a more power-efficient mode will reduce the workload on the CPU and GPU, which in turn reduces heat.
  • Use Lenovo Vantage: If your laptop has the Lenovo Vantage app, it may offer thermal management options that let you prioritize cooling over maximum performance. 

4. Close intensive applications

Check for apps that are consuming a lot of resources and close them, especially when the laptop feels hot.

  • Check Task Manager: Use Ctrl + Shift + Esc to open the Task Manager and look at the “CPU” column under the “Processes” tab. Close any programs that show unusually high usage.
  • Update software: Outdated graphics drivers can sometimes be inefficient and cause more heat. Use Lenovo Vantage or Windows Update to ensure all drivers and the BIOS are up to date. 

If the problem continues

If cooling measures don’t solve the problem, the overheating may have caused permanent hardware damage to the display or the integrated graphics chip.

  • Test with an external monitor: Connect your laptop to an external monitor via HDMI or USB-C. If the external display shows a clear picture, the issue is with your laptop’s built-in screen or the cable connecting it.
  • Contact Lenovo support: If the problem persists, the issue is likely hardware-related. Contact Lenovo support for professional diagnosis and repair.

What is mojibake

Mojibake is garbled, unreadable text that appears when a computer uses the wrong character encoding to decode text. It happens when text encoded with one system is interpreted by another, leading to symbols being replaced by unrelated ones, often from a different writing system. For example, a single character might be broken into multiple pieces of gibberish, or a phrase can become nonsensical.
 

What causes mojibake?

  • Incompatible character encodings: The most common cause is a mismatch between the encoding used to create the text and the encoding used to display it. 
  • Incorrect parsing: When text is sent from one system to another (like from a database to a web page), the receiving system may not recognize the original encoding and uses a different one to interpret the bytes. 
  • Misinterpreted characters: Some character encodings are single-byte, while others are multi-byte. A multi-byte character can be incorrectly broken into smaller pieces, leading to unreadable gibberish.

What does mojibake look like?

  • It can appear as a sequence of random, unrelated characters, often from a different alphabet. 
  • It can also result in a specific type of error, like the 锟斤拷 sequence, which is often seen when a system incorrectly interprets UTF-8 encoded data as GBK. 
  • A common example is when the character ‘ö’ (o-umlaut) is misinterpreted, leading to a sequence like ‘ö’ in some cases. 
  • Sometimes, mojibake will display as a diamond-shaped question mark (), which indicates a character couldn’t be rendered at all.

how to delete removed by google and suspended by google app from play store

It is not possible to delete an app from the Play Console once it has been “Removed by Google” or “Suspended by Google”. For auditing purposes and to prevent developers from circumventing policy violations, Google permanently keeps these apps in your account. 

While you cannot delete the app, you have two primary options for how to proceed: appeal the removal or publish a new version under a different package name. 

Option 1: Appeal the suspension

If you believe your app was removed in error, you can appeal the decision.

  1. Review the policy violation: Carefully read the reason Google gave for the removal or suspension. Your app cannot be reinstated if it still violates Google’s policy.
  2. Fix the app: Correct the issues identified by Google. This may involve removing violating content or features.
  3. Submit an appeal: Use the official appeal form to explain the changes you have made to bring the app into compliance. In your appeal, describe what you fixed and how it now meets the policy.
  4. Wait for review: Google will review your appeal. If it is successful, the app may be reinstated. 

Option 2: Publish a new version (with changes)

If you agree with the policy violation or your appeal is denied, you can publish a new version of the app as a brand new entry. 

  1. Ensure compliance: Create a new version of your app that fully complies with all Google Play policies. The old, suspended version remains associated with your account and cannot be updated.
  2. Use a new package name: Since package IDs are unique and permanent, you cannot reuse the package name from the suspended app. You will need to create a new app with a slightly different package ID.
  3. Upload the new app: Submit the new, policy-compliant version to the Play Console for review, just as you would for any new app. 

What happens to a removed or suspended app?

  • For users: Users who already have the app installed on their devices can continue to use it, but they will not receive any further updates. New users will not be able to find and download it from the Play Store.
  • In your console: The app will remain in your Play Console’s “All apps” list with a “Removed” or “Suspended” status. The listing is not visible to the public.

how to access my pc on wan using Tailscale (works on any OS)

Tailscale is one of the safest and simplest ways to access your PC from anywhere without touching your router. It creates a secure mesh VPN that works on Windows, Linux, Mac, Android, iOS.

Here’s the full guide:


Step 1: Install Tailscale

  1. Go to https://tailscale.com/download
  2. Install Tailscale on:
    • Your PC (Windows/Linux/Mac).
    • The device you’ll connect from (laptop/phone).

Step 2: Sign In

  • After installation, run Tailscale and sign in with Google, Microsoft, GitHub, or Apple ID.
  • Both devices must sign in with the same Tailscale account (or be invited under the same network).

Step 3: Get Tailscale IP

  • On your PC → open Tailscale app.
  • You’ll see something like: 100.x.x.x (This is your PC’s private Tailscale IP).

Step 4: Connect from Another Device

  • On your other PC/phone → install Tailscale and sign in.
  • Your remote PC will appear in the device list (by hostname).
  • Use the Tailscale IP to connect:
    • Windows Remote Desktop: mstsc → 100.x.x.x
    • SSH (Linux): ssh user@100.x.x.x
    • VNC/Other apps: point to 100.x.x.x.

Step 5: (Optional) Enable MagicDNS

  • In Tailscale admin panel → enable MagicDNS.
  • Now you can use hostname (e.g., mypc.tailnet-xyz.ts.net) instead of remembering IP.

Advantages of Tailscale

  • No router configuration needed.
  • Works even on mobile hotspots or CGNAT ISPs.
  • End-to-end encrypted (WireGuard protocol).
  • Free for personal use (up to 20 devices).

how to access my pc on wan using public ip without configuring router

Normally, to reach a PC from WAN you need to forward ports on the router (because NAT/firewall blocks inbound traffic).
If you don’t want to configure the router, you’ll need to use alternatives that bypass port forwarding:


Methods to Access Your PC Without Router Port Forwarding

1. Use a Remote Access Service (Easiest)

  • AnyDesk, TeamViewer, Chrome Remote Desktop, or RustDesk.
  • These tools create an outbound connection from your PC to their server.
  • Since outbound connections are allowed by default, no router setup is required.
  • You connect using an ID/password or Google account instead of a public IP.

2. VPN with Cloud Relay

  • Use a ZeroTier, Tailscale, or Hamachi (LogMeIn) VPN client.
  • Your PC joins a virtual LAN via the cloud → you can access it directly from anywhere.
  • Works without router changes.

3. Reverse SSH Tunnel (Advanced / Linux, WSL, or Git Bash on Windows)

  • From your PC, open an outbound tunnel to a server with a public IP (like a VPS). Example: ssh -R 2222:localhost:22 user@your-vps-ip
  • Then, from anywhere, connect to the VPS on port 2222, which forwards back into your PC.
  • Needs a VPS or cloud server.

4. Cloud-based Desktop (if security is main concern)

  • Instead of exposing your home PC, run a cloud VM (AWS, GCP, Azure, DigitalOcean) and access it securely.
  • You can sync files from home → cloud and then use the VM.

Recommendation

If you just want easy, safe remote access:

  • Windows → Chrome Remote Desktop / AnyDesk
  • Cross-platform → Tailscale (free, private VPN)

Both work without touching your router.

how to access my pc on wan using public ip

Steps to Access Your PC via Public IP

1. Find Your Public IP

  • On the PC → open a browser → search “What is my IP”.
  • Example: 123.45.67.89.

2. Enable Remote Access on Your PC

If using Windows (Remote Desktop):

  1. Open Settings → System → Remote Desktop → Enable Remote Desktop.
  2. Note your PC username and password.

If using Linux:

  • Enable SSH (sudo systemctl enable ssh && sudo systemctl start ssh).
  • Or install a VNC server (tightvncserver, x11vnc, etc.).

3. Configure Your Router (Port Forwarding)

  • Log in to your router (usually 192.168.0.1 or 192.168.1.1).
  • Find Port Forwarding / Virtual Server.
  • Forward the correct port:
    • RDP (Windows Remote Desktop): TCP 3389 → your PC’s local IP.
    • SSH (Linux/Mac): TCP 22 → your PC’s local IP.
    • VNC: TCP 5900.

Example:
Forward TCP 3389192.168.1.100.


4. Access From Outside

  • From another PC/phone (outside your home network):
    • For Windows Remote Desktop:
      • Open “Remote Desktop Connection” → enter 123.45.67.89:3389.
    • For SSH (Linux/Mac): ssh user@123.45.67.89
    • For VNC: use a VNC client → connect to 123.45.67.89:5900.

5. Secure It

  • Don’t expose RDP/SSH directly on default ports → change to custom port (e.g., 2222 instead of 22).
  • Use a strong password.
