My Lenovo Z570 laptop is acting weird these days.

When I make it sleep or hibernate, and leave it for minimum 30~45 minutes,and try to start d laptop HDD light will be always ON and windows will not start. Sometimes blue screen come and suddenly laptop restarts. And then, if I go to BIOS and check for HDD, it will not be there in the Boot options.


Later is shows,


If I press n hold the power button and make the laptop completely turn off and start it,even then this problem persists. After 2 or 3 tries, Windows starts to boot and evrything will be normal and performance is as it is. No decline at all.

So I even tried to shutdown my laptop and use it after some time, for eg after 30 or 40min. The same problem occurs.

What can be the problem with? Pls help.

Update 17-08-2014

  • I travelled with my laptop in a bus for 12hrs and surprisingly this problem disappeared and my laptop started working fine!
  • For a safety check, I've taken my laptop to the authorized service center and we are unable to replicate the scenario as it was working fine. Technician checked with some Lenovo's S/W(PC doctor) and concluded that there is no H/W problem. He reconnected and adjusted all the cables and returned it to me. To my fate, the problem is back again after 2 days :( and it started to appear as frequent as it was before!

So what can be the problem! I'm ready to replace any hardware part! But still waiting for the solution.

seems to me as a hardware related, is the device under warranty still? if yes, go for this, if no then you are free to open it and check if the hdd is connected properly and fixed. – Ruslan Gerasimov Jul 20 '14 at 10:21
NO..its not under warranty now :( – Shiva Mothkuri Jul 20 '14 at 10:21
Probably a hardware issue, as @RuslanGerasimov suggested you should check that the HDD is properly connected (sometimes simply disconnecting/reconnecting it can do miracles), otherwise you may hope that the problem is known and a BIOS update is available to fix it, if it isn't the case then you should replace the mainboard. – user256743 Jul 20 '14 at 10:42
@AndréDaniel I agree with your comment about BIOS update. But before thinking the MB is bad I would test the drive on other machines, I believe it could be the drive failure. – Ruslan Gerasimov Jul 20 '14 at 10:48
@RuslanGerasimov good point, you should also test with another hard drive if possible. – user256743 Jul 20 '14 at 10:49

Temporary Workaround

I have also been going through the same problem but as a temporary workaround, it just boots fine (and finds the hard disk) every time if you connect it to the charger before turning it on.

Further Observations

It's probably not the hard-disk nor the OS (in my case I have tried different HDDs and an SSD, besides trying my HDD in another machine; and I run Linux not Windows).

Tried replacing my HDD with my friend's HDD and found everything working fine!

Got a new HGST 500GB HDD and voila! problem has disappeared. Will buy casing for my old HDD and use as external HDD till it dies :D
