Drivers and the BIOS control your computer's hardware. Updating them fixes many problems with sleep, battery, Wi-Fi, audio, screens and docks, and improves security.
1. Start with Windows Update
Open Settings > Windows Update, install everything, then check Advanced options > Optional updates > Driver updates.
2. Use your maker's update tool
These tools find the right drivers and BIOS for your exact model.
| Brand | Tool |
|---|---|
| Dell (Latitude, OptiPlex, Precision) | Dell Command Update, or Dell SupportAssist |
| HP (EliteBook, ProBook, EliteDesk, ZBook) | HP Support Assistant, or HP Image Assistant for business models |
| Lenovo (ThinkPad, ThinkCentre) | Lenovo Vantage, or Lenovo System Update |
| Microsoft Surface | Windows Update installs Surface drivers and firmware |
You can also download drivers from the maker's support website using your computer's service tag (Dell) or serial number (HP and Lenovo). It's on a sticker underneath, or in the BIOS.
Updating the BIOS safely
- Plug the laptop in and make sure the battery is above 50%.
- Close all programs and save your work.
- Suspend BitLocker if you're updating manually. Search for Manage BitLocker and select Suspend protection. Maker tools usually do this for you. If you skip it, you may be asked for your BitLocker recovery key afterwards (article 18).
- Run the update and don't touch the computer. The screen may go black and the fans may get loud for several minutes, with a few restarts. Never turn it off during a BIOS update.
A driver update caused problems? In Device Manager, right-click the device, select Properties > Driver > Roll Back Driver, and restart.
Avoid third-party "driver updater" programs. They often install the wrong drivers or unwanted software. Stick to Windows Update and your maker's tool.
