Lenovo G700 starts from power off after one hour

Hi,

My G700 is three years old, on W8, no problem until now.

When I put it in sleep mode, it starts back immediately when I press a key or raise the cover.

But if I put it in full power off, it goes off but then, I have to wait between one up to three hours recently, to get Windows start screen. I mean the power starts, fan starts, disk Led is on (battery Led too), but nothing else, the screen is off (so black).

 

The case is not as other "black screen" cases, where the screen stays black whatever they do. In my case also I can do nothing to get Lenovo logo at power on, I cant enter Bios setup. I tried also to remove battery, power cord and press Power button to discharge condensators, then connect power cord, nothing but the fan and disk runing and disk led on.

 I just can wait one hour or more.

 

The only explanation I can see, is one month ago, the first time it happened, I was using Avast free antivirus, and Avast did a new update. So I was thinking after this update, that Avast starts a long full scan at power on, so I removed Avast and activated Windows Defender. No problem when I used just sleep mode and wake up. But same problem when I put the comp in full power off.

Maybe Windows Defender starts also a full scan at that time?

 

Now I use only sleep mode ; yesterday I travelled for 10 hours, and the comp started immediately when I pressed a key!

 

I will be pleased to have any advice from you.

Re: Lenovo G700 starts from power off after one hour

Sometimes it can be related to disk scanning at start up, either by anti-malware software or even windows OS (chkdsk.exe) if it has been scheduled to run due to a compromised sector or SMART error on the hard disk drive.

You can run tests on the hard disk using manufacture software or Lenovo tools to see if there are hardware faults, also you can run a system file check by opening up the command prompt window then running SFC /SCANNOW to have any corrupted system files repaired / replaced.

Re: Lenovo G700 starts from power off after one hour

Thanks for answer,

I will do sfc scan after last use of comp today and keep you informed.

 

What I read about automatic chkdsk, is that there is a message on screen before the check starts, this is not my case because the display is off.

 

I checked in registry, that the value for the BootExecute key is autocheck autochk *, do I have to change it and stops the check for ever?

 

Wait and see

Re: Lenovo G700 starts from power off after one hour

Here is what I tried :

- While my comp was runing, I started sfc /scannow  that last some minutes, ending with a message "there was some files erreor, some are repaired, some are not repaired"!!!

- Then I started a chkdsk, and I got the message saying it is not possible to run chkdsk until I logoff, and asked me if I want to run it at next power on, and I agreed

- so I restarted my comp and... black screen for about 7 hours

- then looking from time to time the screen I noticed that the Lenovo logo was displayed with a message under saying there was a scanning and repair operation on the disk, and 14% progress value that stays constant for a long time, until I noticed that the screen was off again

- the screen is off since 2 hours now.

 

I presume that after the chkdsk, the comp restarted with the same black screen problem, so I have to wait one more hour!

 

Wait and see

Re: Lenovo G700 starts from power off after one hour

Worst and worst. It seems that each time I restart the comp, the black screen duration increase! At the begining, it was around 1 hour, then 3 hours, now it is one day long!

I checked the event viewer at the period before my last post, you will see that when the event time was at 14:04:45, the next event is at 22:36:42 (eight hours later) and indicating :

The EventSystem subsystem will filter duplicate event log entries for 86400 seconds (=24 hours). The timeout of this function is set by using the REG_DWORD value registered as SuppressDuplicateDuration in the following registry key: HKLM \ Software \ Microsoft \ EventSystem \ EventLog.

I wonder what happened between these two events.

I also wonder this event :

22:36:44 id 0 igfxCUIService 1.0.0.0
The description of event ID 0 in the source igfxCUIService1.0.0.0 was not found.

I attached a file with list of events

Now I'm tired of waiting days between each tests, so I change my tests by using a different HDD, containing W7 ; same problem of black screen for some hours. I succeed to change boot mode to legacy, waiting now that I could boot on a DVD or on a USB stick with W8 in it.

I presume now the problem is not in Windows 8 or 7, but in the motherboard. I changed the CMOS battery and wait next start!

More worst ; now the comp doesn't stay running, even pressing power on or novo button.

 

I hear that the disk starts, webcam led and power led flash for one second, then the disk stops, and this sequence sarts again five seconds later, but the fan doens't start, except if I remove the memory sticks!

If I disconnect the power supply, so using ony battery, the webcam and front leds flash once only.

 

I checked the power supply voltage is between 20.4 V in iddle state and 20.3V when the disk starts.

 

I presume some component  died slowly in the mother board.

 

So I give up!

Re: Lenovo G700 starts from power off after one hour

If it acts up when the AC adapter is plugged in it may be linked to the AC / DC supplied to the board, or the power in connector on the system board as well.

Can you try a known good AC adapter to see if that makes a difference?
