Hello and welcome to dtptips! Today, we’re diving deep into a topic many PC and laptop users are either scared of—or completely ignore: BIOS updates.
We all know how to access the BIOS by pressing keys like F2, F10, ESC, or DEL during startup. But should you really update it? Is it risky? And what happens if things go wrong?
Let’s explore what BIOS really is, when and why you should update it, what risks are involved, and what recovery options you have if your BIOS gets corrupted.

🧠 What Exactly is BIOS (or UEFI)?
Before we get into updates, let’s understand what BIOS is.
BIOS stands for Basic Input Output System. It’s a firmware chip on your motherboard that:
- Boots your operating system (Windows, Linux, etc.)
- Initializes hardware like keyboard, mouse, CPU, RAM, GPU
- Lets you change system-level settings (like boot order, power features, XMP profiles, etc.)
⚠️ Technically speaking, modern computers use UEFI (Unified Extensible Firmware Interface), which is a newer version of BIOS. But in everyday usage, people still call it “BIOS”, and we’ll stick with that in this article for simplicity.
📝 What You Can Do Inside BIOS
Once you enter the BIOS setup interface, here’s what you can usually configure:
- Enable XMP for RAM overclocking
- Change boot priority
- Manage power settings
- Enable virtualization
- Adjust CPU/GPU clock settings
- Control fan speeds (in some models)
Note: Available settings depend on your laptop/PC brand and model.
🤔 Is BIOS Update Really Important?
The answer is Yes… and No.
You should not update BIOS just for fun or curiosity. However, in some scenarios, it’s necessary and even recommended.
Let’s break it down.
✅ Reasons to Update Your BIOS
- Fix Hardware Issues: If your laptop keyboard, touchpad, battery, charging port, or power button isn’t working properly.
- Solve OS Instability: Frequent crashes or freezing in Windows could be fixed with a BIOS update.
- Improve Compatibility: For example, you’re adding new RAM, SSD, or GPU and the system doesn’t detect it properly.
- Enable New Features: Some BIOS updates unlock features like Resizable BAR, new CPU support, etc.
- Fix Security Vulnerabilities: Manufacturers often patch critical flaws through BIOS updates.
- Performance Optimization: In rare cases, BIOS updates may improve system performance or stability.
💡 Tip: In my personal experience, I had a trackpad issue that was resolved only after updating the BIOS.
🚫 When You Should NOT Update BIOS
- Your system is working perfectly and doesn’t need new hardware
- You’re not experiencing any bugs or crashes
- There are no critical features you need in the BIOS changelog
Updating BIOS when it’s not needed exposes you to unnecessary risks.
⚠️ The Real Risk of BIOS Updates (Don’t Ignore This!)
Updating BIOS isn’t as simple as a Windows update. If things go wrong, your entire motherboard could become useless.
Here’s what can go wrong:
- ❌ Wrong BIOS file: Installing a BIOS not meant for your motherboard can kill it.
- ⚡ Power Loss during Update: If your system shuts off mid-flash, BIOS gets corrupted and your PC won’t boot.
- 🛑 Interruptions: Antivirus, system crashes, or user interference during update can brick the BIOS.
😱 Without BIOS, your PC can’t even start the operating system!
✅ Must-Follow Precautions Before BIOS Update
Here’s your survival checklist before proceeding:
- 🔋 Keep your laptop plugged in (don’t rely on battery only).
- 💾 Back up all your important data (just in case).
- 📦 Close all applications, including antivirus and background processes.
- 🧬 Double-check the BIOS file—download only from your manufacturer’s official website and for your exact model number.
- 🧘♂️ Do not touch or interrupt the process once it begins.
If you’re on a desktop, use a UPS or inverter during the update.
🔄 What If BIOS Update Fails or Gets Corrupted?
Relax, it’s rare—but here’s what you can try if your system doesn’t boot after a failed update.
1. 🔁 Automatic BIOS Recovery (Brand Dependent)
Some manufacturers like Dell and HP provide built-in recovery tools that:
- Load a backup version of BIOS
- Recover using a special key press or boot USB
👉 Visit your manufacturer’s site and search for BIOS recovery tools. Dell and HP have official documentation (check their support pages).
2. 💾 BIOS Recovery via USB Flash Drive
Many systems allow creating a BIOS recovery USB:
- Download the correct BIOS file on another working PC
- Copy it to a FAT32-formatted USB
- Plug into corrupted system
- Use BIOS key combo to start recovery (varies by brand)
3. 🧬 Dual BIOS Feature
Some high-end motherboards come with two BIOS chips. If one fails, the second one can boot and recover the first. This feature is usually on gaming or custom PCs.
4. 🔌 BIOS Flashback Port (on Desktops)
If your desktop motherboard supports it:
- You can flash BIOS even without CPU or RAM installed
- Just insert the BIOS file in a USB drive and use a dedicated port and button
Again, this is brand-specific and only for desktops.
5. 🛠️ Professional Service / Chip Replacement
As a last resort:
- Send the board to your brand’s service center
- Some local technicians can replace the BIOS chip or use a clip + SPI programmer to reflash it
Yes, it’s costly and not ideal—but it saves the board.
💡 How to Check What’s New in a BIOS Update?
When you go to the official BIOS download page:
- Look at the changelog or version history
- It lists what’s fixed or added in each version
- This helps you decide if the update is necessary
🤷♂️ FAQ – Frequently Asked Questions
Q1: How often should I update my BIOS?
Not frequently. Only if you’re facing problems, upgrading hardware, or see critical fixes in the changelog.
Q2: Will BIOS update improve gaming performance?
Not directly. But if it’s fixing RAM timings, CPU boosts, or GPU compatibility, it might.
Q3: Can BIOS update fix blue screen errors?
Sometimes yes, especially if related to hardware compatibility or CPU/driver bugs.
Q4: Is BIOS update dangerous for laptops?
Only if done incorrectly. Laptops are safer since they have built-in batteries—but still, follow precautions.
Q5: How do I know if my laptop has BIOS recovery?
Check your brand’s support site. Dell and HP usually offer good recovery tools.
🧭 Final Thoughts
Updating BIOS isn’t something to fear—but it’s definitely not for fun either. If you’re facing hardware issues, crashes, or installing new components, a BIOS update may be exactly what your system needs.
Just remember:
- Update only if needed
- Follow all precautions
- Check recovery options for your brand
Done right, a BIOS update can breathe new life into your system.
