Hi,
My old Lenovo z580 has been powering off suddenly without any apparent reason, after ruling out faulty battery (by running it on AC only), faulty AC (by running just on battery), or fans (Core Temp says it's quite cool while powering off), I found out that HDD is apparently failing - so, I backed up all the data (laptop failed several times during this but turned back on) and tried to shut it down before going to shop for new drive.
Problem is, it got stuck while shutting down - screen is off, power led button is on as are other led buttons, HDD is making a constant quiet noise, and it won't either turn back on or completely turn off. Pressing power button doesn't do anything. I considered taking out the battery but I don't know if it's safe to do when laptop is (sort of) working?
