Lenovo Z50-70 won't boot up

Hi,

I have encountered a problem with my Z50-70 with Windows 10 on it.

I am turning on my laptop and it tries to boot: the Lenovo logo appears for 1 second before it fails and starts again the process but his time it stays on even less time. And then it tries again to boot but it stays on even less time. I can tell that it's trying to boot because I hear the fan turning on and off for a couple of times and each time it is turning on for a shorter period.

And then after I wait a couple of days and try to boot it again and he loads Windows normally. And then again now same error.

Anyone at Lenovo willing to help??? I have had my laptop for 4 years. That's not long after my standards. My last Dell laptop lasted for 7 years.

 

I also tried to boot it with or without battery, I disassembled it and replaced the cooling paste on the CPU and GPU but still no succes. I also bought a new charger and tried with it to no avail.

 

Any answer from anyone, especially the tech guys at Lenovo would be appreciated.

 

Have a nice day.

Re: Lenovo Z50-70 won't boot up

Hi Magnus100,

 

Welcome to the Community Forums.

 

I would suggest that you backup all your things once you manage to boot it up otherwise I recommend removing the harddrive out and slave it on another computer.

 

This way we can check if the issue is with the harddrive and Windows or something else internally with the machine.

 

While the machine is without the harddrive, from shut down, try to use the novo button (page9 item2) to power on the machine. This should give you the Novo Menu to access the BIOS. Check if you would be able to move around the BIOS.

 

On the original harddrive, see if the other machine is detects the drive and able to read/backup its content. This helps isolate Windows isssue against the harddrive over POST (power on self test of the systemboard and its components.

 

Update us how it goes.

 

Regards

Re: Lenovo Z50-70 won't boot up

Hi, spidey101.

 

Thank you for your answer. I really appreciate it.

 

I used an Icy box External Enclosure to access the harddrive from my job laptop.

It's reading it. I took a while before he read it: I had to wait a bit before I saw it as a hard drives but I'm guessing it's because I had a lot of data on it.  I copied one of my movies and backed up about 19 GB of pictures from the HDD to my job laptop.

 

By pressing the Novo button I have been able to get to the Novo button menu and access the BIOS.

What should I do next? I don't have a boot up USB. I don't remember if I got a boot CD with the machine but I don't think so.

I don't remember exactly how I installed Windows when I got the laptop.

 

Best,

Magnus

Hi Magnus100,

 

Greetings.

 

As it shows ok on the BIOS screen and that the harddrive still is detectable/ readable then most likely issue maybe with Windows boot up. You can try placing back the harddrive and use the same Novo button to power up.

 

Choose Sytem Recovery and see if one key recovery from initial backup is still ok. Take note that OKR would restore factory image and addplication and data that did not came with the original preload would be removed so data back up is needed.

 

Regards

Re: Lenovo Z50-70 won't boot up

Hello again,

 

Thank you for the advice.

I tried to use the OKR but selecting the first option he said that there isn't enough space on the hard drive. I don't know why he said that because there was ca. 125 GB free on one partition and some 200 GB more on the other. Do you have any possible answers for this?

Choosing the the second option he said that there was no image. 

But this time I managed to boot it and reset the OS. It seems to be working fine now though it takes some more time to shut down.

 

The question is: how do I create an OKR image so that I have it if problems occur again?

 

Regards

Hi Magnus100,

 

During OKR, only C partition is reimaged and other partitions are kept. Since you have backed up all needed files perhaps removing nonessential contents on other partition so that OKR can be done as OKR on initial backup.

 

Do you have Win 8 now and originally on this machine?

 

Here is the article guide to create recovery image:

Re: Lenovo Z50-70 won't boot up

Hi Spidey101,

 

Thanks for the info and the links. I had Windows 8 originally on the machine but now I have Windows 10.

However, I have almost the same problem again.

 

After resetting the PC I've reinstalled Panda, Power DVD and VLC media player. I've also installed Defraggler and defragmented partition C.

I've watched a couple of episodes from a TV-series from a DVD. This was on Thursday.

On Friday I booted the computer and it would load Windows 10 but it would restart after one minute and a half. He did this several times. In the end it would spend less and less time trying to load Windows before restarting.

 

I've been away in the week-end. When I came back home I booted the computer and now it starts, since I can hear the fan moving but I have no image on my display. Any thoughts about what could be wrong?

 

Regards.

Hi Magnus100,

 

Greetings.

 

Try to shutdown and turn on the machine with the Novo button. Once on the BIOS and load defaults (F9) then save and exit.

 

If it does the safe then try safe mode and check if its booting to Windows.

 

Regards

Hi spidey101,

 

I tried. Unfortunately it does not boot using the Novo button. It's restarting itself every time (sometimes just for a few seconds) and there's no image on the display even when I can hear the fan moving.

Re: Lenovo Z50-70 won't boot up

Hi Magnus100,

 

Greetings.

 

I am starting to doubt the integrity of the original harddrive. Perhaps you can consider testing it with another harddrive or run a test on the original harddrive placed on an enclosure.

 

Regards
