aio700-27 ISH high system interruption

[Marcuk]

From the purchase of AIO 700-27 ISH  I experience very high percentage of CPU usage by system interruptions (up to 30 !) which is way much compared to second PC with only up to 5 %. The system is also very slow with common hangouts. Lenovo hardware screeening tool shows no errors and i even replace original SSHD with SSD drive which solved vera high HD usage (often 100 % vs. several % after SSD installation) but, unfortuntalelly system interruptions remain high. Has anybody similiar expereience? What should I do?

Hi @Marcuk

Welcome to Community Forums!

Let's try these:

1. Check For Windows Updates

2. Check Disk For Errors

• Open command prompt ( run as administrator )
• Type the "chkdsk C: /f" command and press Enter from your keyboard
• To repair physical issues, also run the "chkdsk C: /r"
• You can run both commands at once by typing "chkdsk C: /f /r" (Windows will need to restart the computer to finish the scan). The disk checking process can take some time, depending on the computer power and size of hard drive. Be patient and wait until it completes.

3.Unplug External Devices

4. Update Device Drivers

• open Device Manager by right-clicking the Start button and selecting the "Device Manager" and look for devices marked with yellow exclamation marks and update those. 
• If the yellow bangs still remains its better to uninstall those drivers and restart the computer

5. Disable Audio Enhancements

• To disable sound enhancements, right-click the speaker icon in the Taskbar.
• Select the "Playback devices" option from the contextual menu
• The Sound window will appear and you will be automatically directed to the Playback tab. Select the default audio device that you use for playing audio and click "Properties".
• In the Speakers Properties window, select the "Enhancements" tab and ensure that none of the enhancements are enabled, or simply tick the "Disable all enhancements" checkbox and click "Apply" to save the changes.

6. Disable Wake on Magic Packet

• To disable this feature, open Device Manager and select your Ethernet or Wi-Fi network adapter.
• Right-click it and select "Properties". In the Properties window, find the "Advanced" tab and select it.
• You will see a list of properties available for the network adapter. To change Wake on Magic Packet settings, scroll down until you find this feature and select it. Then set its value to "Disabled" on the right side of the Properties window. Save the changes and restart your computer.

7. Update BIOS

8. Disable Fast Startup

• To disable Fast Startup, go to Search and type "power".
• Click on the "Choose power plan" result to open it.
• In the Power Options window, click "Choose what the power button do".

Click on "Change settings that are currently unavailable" and then uncheck the "Turn on fast startup (recommended)" option if it is enabled. Click "Save changes" to save the changes made, restart your computer and see if System Interrupts is still causing high CPU usage. If the problem persists, you can re-enable Fast Startup if needed.

Hi, I already tried all the above mentioned steps with no success. I even disabled some devices like audio and blue tooth. Initially I suspected hard drive to be a reason as disk usage in the task manager was very high (often 100%) and computer was realy very slow. After replacement of HDD with SSD the disk usage in task manager is very low and the system is much faster but system interruptions are still very high, even above 30 %. Is mechanical service only option or can I do something more in the software. All hardware scanning utilities shows perfectly healthy system.
