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.
Operating System: Windows 7 Ultimate 32-bit (6.1, Build 7601) Service Pack 1 --fresh install
Processor: Intel(R) Core(TM) i5-2430M CPU @ 2.40GHz (4 CPUs), ~2.4GHz Memory: 4096MB RAM
HDD : Western Digital 750GB (WDC WD7500BPVT-24HXZT3)
Result of HDD check:
- 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.
