I have been experiencing some difficulty with my Z560 for a few weeks. It is slow, it freezes, shuts down, and is sometimes not responsive to any keystroks.
It does not respond to CTRL-ALT-DEL to start task manager , requirig me to shut it down manually by holding the power button for 5 seconds. This has been going on for about a month now.
I have done the hardware scan test a few times and today the computer failed the "SMART short self test" as well as the "SMART drive self test". My research tells me that this is a warning that the hard drive is failing.
The Lenovo Hardware test site tells me to contact Lenovo with the following result code: WHD01V01G-7H9W8J.
Where do I send this code? Is this, indeed, a message that my hard drive is beginning to fail ?
If the result of "SMART short self test" and "SMART drive self test" suggest that the hard drive has indeed failed. Then you may want to do a repair or have a brand new hard disk.
You will first be required to do a back up of all your data while the hard drive can still be accessed.
Once the backup is done, immeadiately contact the Lenovo technical support and they will guide you further.
