## Section 1: The Critical Role of Correct Drivers for Your E120
Drivers are the essential software that allows your ThinkPad E120's operating system to communicate with its hardware. Using incorrect, outdated, or missing **Lenovo ThinkPad E120 drivers** is the root cause of a significant majority of performance issues reported by users.

* Unexpected system crashes or the infamous "blue screen of death" (BSOD).
* Poor battery life or incorrect charge status reporting.
**The Official Source:** The only guaranteed source for compatible drivers is the Lenovo Support website. Always use your specific machine type and model (e.g., **ThinkPad Edge E120**) to search.

## Section 2: Solving Common ThinkPad E120 Driver Issues
### 2.1 Wi-Fi and Network Adapter Driver Problems
This is one of the most common **Lenovo ThinkPad E120 troubleshooting** topics on the forum.
**Problem:** The wireless network disappears, shows as disabled, or fails to connect after waking from sleep or a fresh boot.
**Solution:**
1. **Update the Driver:** Navigate to Lenovo Support, enter your E120 serial number, and download the latest Wireless LAN (WLAN) driver. Common adapters in the E120 include Realtek and Broadcom models.
2. **Power Management Fix:** A confirmed fix from user forums involves disabling the wireless adapter's power-saving feature.
* Go to `Device Manager` > `Network adapters`.
* Right-click your Wireless adapter > `Properties`.
* Go to the `Power Management` tab.
* **Uncheck** "Allow the computer to turn off this device to save power."
3. **Perform a Power Reset:** If the adapter isn't detected at all, shut down the laptop, disconnect the AC adapter and battery (if removable), hold the power button for 30 seconds, then reconnect and power on.
### 2.2 Display Brightness Control Not Working
**Problem:** The `Fn + Home/End` keys do not adjust screen brightness.
**Solution:** This is almost always caused by missing utility drivers.
1. Install the **Hotkey Features Integration** driver (sometimes called "On Screen Display" utility) from the Lenovo support site.
2. Additionally, ensure the **Intel HD Graphics driver** (or the appropriate chipset driver) is up to date. The brightness control is managed through these drivers.
3. After installation, restart your **ThinkPad Edge E120**.
### 2.3 Touchpad and Pointing Stick (TrackPoint) Issues
**Problem:** The touchpad is unresponsive, or the TrackPoint buttons stop working.
**Solution:**
1. Install the latest **Synaptics Pointing Device Driver** (or the equivalent Alps driver) from the Lenovo E120 driver page.
2. In the `Mouse Properties` control panel, check the settings to ensure the device is not disabled.
3. Some users have reported success by rolling back to an older, more stable version of the pointing device driver if the latest one causes problems—a key **troubleshooting** step often overlooked.
## Section 3: General System Troubleshooting and Maintenance
Beyond drivers, these practices can resolve broader system instability on your **Lenovo laptop**.
### 3.1 Resolving Random Freezes and Slow Performance
1. **Update BIOS/UEFI:** Check Lenovo Support for a BIOS update for the **ThinkPad E120**. BIOS updates often improve system stability and hardware compatibility. Follow the included instructions *precisely*.
2. **Run Hardware Diagnostics:** Boot your E120 and press `F10` during startup to launch the **Lenovo PC Diagnostics** tool. Run the memory (RAM) and hard drive tests to rule out failing hardware.
3. **Thermal Management:** The E120 can accumulate dust. Use compressed air to carefully clean the vents. Consider repasting the CPU if the system overheats and throttles frequently.
### 3.2 Optimizing for Windows 10 (Common Upgrade Path)
Many E120 users have upgraded from Windows 7 to Windows 10. For best results:
* After a clean Windows 10 install, use **Lenovo Vantage** or the **Lenovo System Update** tool to automatically detect and install all necessary drivers tailored for your specific E120 configuration.
