I have a Lenovo 710S-13IKB Laptop (Ideapad), and it's extremely slow.

When I first turn on the computer, it runs smoothly for the first 20-30 seconds, with the processor showing a speed of 3.00 GHz in the Task Manager. However, after that brief period, the processor speed drops sharply to 0.38 GHz and remains stuck there, causing the computer to become painfully slow.

I've researched the issue online and suspect it might be related to the BIOS. Although the BIOS is updated to the latest version, I believe downgrading it might help. Unfortunately, I haven’t been able to find an older BIOS version on Lenovo’s website.

PS. I already format the computer twice, changed the NVMe disk and the problem remains the same.

Hi samuel331!

Welcome to the Community!

Sorry to hear about the performance issues with your Lenovo 710S-13IKB. Here are a few steps you can try to resolve the problem:

1. Check Power Settings: Ensure that your laptop is set to "High Performance" mode in the power settings. Sometimes, power-saving modes can throttle the CPU speed.

2. Thermal Throttling: The CPU might be throttling due to overheating. Make sure the cooling vents are not blocked and consider cleaning the fan and applying new thermal paste if you're comfortable doing so.

3. Lenovo Vantage: Install the Lenovo Vantage app. It can help you update drivers, run diagnostics, and manage power settings.

4. BIOS Settings: Double-check the BIOS settings to ensure there are no power-saving features enabled that could be limiting the CPU speed.

5. Adjust Power Management in Control Panel: Go to Control Panel > Hardware and Sound > Power Options > Change plan settings > Change advanced power settings. Expand Processor Power Management and set Minimum / Maximum Processor State for both Plugged in and On Battery settings:
   Minimum - 5%
   Maximum - 100%
   (can be reduced / increased depending on which works best for you)

I hope this helps! Update us how it goes.

Best regards,

Sorry to hear that the issue persists. Since the initial steps didn't resolve the problem, I recommend the following additional actions:

1. Check for Thermal Throttling: Use a tool like HWMonitor to check if the CPU temperature is causing throttling. If temperatures are high, it might be worth reapplying thermal paste or checking the cooling system.

2. Run Lenovo Diagnostics: Use the Lenovo Vantage app to run a full system diagnostic. This can help identify any hardware issues.

3. Service Request: If none of the above steps work, it might be best to submit a service request or visit a local authorized service center for a thorough check. You can also reach out directly to support via phone here https://pcsupport.lenovo.com/supportphonelist
