Slow Hard Disk Response Time

I have a laptop computer running Windows 10. The performance has become unbearable.

Looking at Task Manager, I can see that the Average Response Time sometimes gets over 450 ms, and the Active Time holds steady at 100%.

The drive has plenty of available space. Nonetheless, I ran disk cleanup and checked that fragmentation is not excessive.

This may have started around the time that my laptop was serviced because the battery had swollen up and made the pad buttons hard to press. I'm just trying to get some idea if the hard drive is dying, or if there could be some kind of configuration issue.

You can use the Resource Monitor to check what process is causing the high disk activity. After opening the Resource Monitor switch to the disk tab.
