Lenovo Y700-15ISK black screen of death

Hi,

 

I've a Lenovo IdeaPad Y700-15ISK, model MTM: 80NV0029US, a month ago I was playing just fine, zero problems, but when I shut down the notebook Windows 10 stays for about 15 minutes trying to shut doen the notebook with no success, so I decided to press the power button until the notebook powered off.

 

Later that day when I power up the notebook I got the infamous Y700 black screen of death. I've tried all the solutions, hard reset, reset componentes, disconnect battery, etc, etc with no sucess, only the keyboard backlight power on, but after a while the notebook keeps restarting. All the time the screen is black.

 

My notebook warranty has already expired, what I would like to know if theres is a solution to that issue, I think it has to be the embedded Lenovo controller, that controls the state of the machine (ACPI S3) that is faulty, could I buy that controller anywhere?

 

Regards.

Marcelo Andino

Re: Lenovo Y700-15ISK black screen of death

Hi there, Marcelo        -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

In response to customer reports of Y700-15ISK, Y700-Touch 15ISK, and Y700-17ISK laptops not powering on, or powering on with no display, a solution has made available via BIOS update. 

 

Version 30, CDCN30WW, can be found here:http://support.lenovo.com/us/en/products/Laptops-and-netbooks/IdeaPad-Y-Series-laptops/y700-15isk/do...

 

Update us how it goes.

 

 

 

 

Regards,

First, I'd disconnect the SSD/HDD where Windows is installed and try to start the laptop then.

 

Second, you can use an EEPROM programmer to reflash the BIOS, which might help but is a non-trivial task. I'd read the dump and scan it first for any abnormalities. (You can also replace the ugly boot logo while you're at it. Smiley Happy )

 

Third, you can get a second-hand replacement motherboard from another donor laptop. The model is Compal BY511 (or BY513 but rather unlikely).

Ive already reprogrammed the bios with no success. Also I used the latest one.

 

its like the notebook keeps restarting.

 

I think there is a motherboard component that isn't working properly. I've checked all the mosfets and they seem.ok.

Re: Lenovo Y700-15ISK black screen of death

You've probably thought about this already but I'd also put the CPU and memory in another motherboard to make sure they are OK. If either of the two were faulty, the symptoms could be much the same. Also, unplug the battery and try to make it start from AC power only.

 

I had similar symptoms on another laptop years ago and the cause then was a soldering defect around the power jack. It would actually still power on correctly if pressure was applied to that area of the motherboard. At the time this was a relatively common problem due to the introduction of lead-free soldering for RoHS compliance.

 

If you are absolutely sure the problem is with a certain element you might be able to get a replacement elsewhere separately but for Lenovo, the whole motherboard together with the CPU is an indivisible FRU:

MB L Y700-15ISK NOK I7-6700 4G 5B20K28164
MB L Y700-15ISK WIN I7-6700 4G 5B20K28148
MB L Y700-15ISK NOK I7-6300 2G 5B20K28176
MB L Y700-15ISK WIN I7-6300 2G 5B20K28160
MB L Y700-15ISK NOK I7-6300 4G 5B20K28144
MB L Y700-15ISK WIN I7-6300 4G 5B20K28172

Hi,

 

I've tried everything, put some heat with a rework blow solder but nothing solves the issue.

 

The notebook has less than a year, and I used to play with it about 10 hours a week, no more.

 

Lenovo you've to do something about that, I've spent USD 1600 on this notebook, I live in Uruguay South America, and now its only a piece of crap.

 

Regards,

Marcelo

Re: Lenovo Y700-15ISK black screen of death

Hey bud, I know this is long overdue but I recently fixed the same issue with just a thumb drive. I'm literally going back through all the same related issues and posting the link to what solved the BIOS wipe. Most likely what happened along with dozens of us is that one of the failed Lenovo updates tried to update the BIOS but then stopped it mid way wiping things. This causes it to turn on and off constantly but luckily another guy figured it out. Hope this helps anyone who sees this.
