Why Does My Lenovo Yoga 720 Overheat When Charging Overnight?

If your Lenovo Yoga 720 feels like a toaster after charging all night, you’re dealing with a common problem. Overheating can stem from charging habits, poor ventilation, or system strain. Here’s how to fix overheating when charging and keep your laptop cool.

What Causes Lenovo Yoga 720 Overheating During Charging?

Several culprits might be at play:

• Blocked vents from dust or soft surfaces like a bed.
• High CPU usage from background apps while plugged in.
• Battery charging settings pushing the system too hard.
• Heat buildup if the fan isn’t working efficiently (related to sleep mode issues).

Let’s dive into the solutions.

Step 1: Optimize Charging Settings

Overcharging or constant full-charge cycles can generate excess heat.

1. Open Lenovo Vantage (pre-installed software).
2. Go to “Hardware Settings” > “Battery”.
3. Enable “Conservation Mode” to cap charging at 60%.
4. Test overnight charging—less strain means less heat.

Step 2: Improve Ventilation

Poor airflow is a major overheating trigger.

• Place your Lenovo Yoga 720 on a hard, flat surface—not a pillow or blanket.
• Use a laptop cooling pad for extra airflow.
• Clean vents with compressed air to remove dust.

Step 3: Limit Background Processes

Apps running overnight can overwork the CPU, causing heat buildup.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Check the “Processes” tab for high CPU usage.
3. Disable unnecessary startup programs via the “Startup” tab.

Step 4: Check Fan Performance

A struggling fan can’t cool the system properly.

If your fan seems weak or noisy, it might be tied to sleep mode glitches. See our guide on how to fix a Lenovo Yoga 720 fan that won’t stop running after sleep mode for detailed fan troubleshooting steps.

Step 5: Update Firmware

Outdated firmware can mismanage power and heat.

• Visit Lenovo’s support site.
• Download the latest BIOS and power management updates for the Yoga 720.
• Install and reboot to test.

With these fixes, your Lenovo Yoga 720 should stay cool while charging overnight. Protect your device and enjoy worry-free performance!
