Lenovo y50 Adapter Surge

Hello,

    I have a lenovo y50 laptop that seems to be having an issue.  My laptop has been on most of the day and was at lower power since I did not have time to charge it at all today.  When I got home and I plugged the adapter into the wall then plugged it into my computer, I heard the noise of the laptop screen instantly going black.  When I looked back at my laptop I saw that the screen what black, the laptop was off, and none of the lights at the bottom left of the laptop were on even though the adapter was plugged in.  I also then began to hear a chirping noise that was coming from the power adapter which stopped when I unplugged it from my laptop.  I then tried hitting the power button multiple times but the laptop would have no response at all.  My suspicion is that the adapter went bad and sent a surge to my laptop.  Does this mean that my batteries dead or has the whole thing been killed?  Also, if there is any suggestions that you have that I can do to find the problem/troubleshoot I would greatly appriceate it.  Thanks for any responses.

Hi Nozshund , 

 

Welcome to the Community Forums. 

 

Would you have the Machine number from the sticker or to get it from here (just keep the serial number confidential).  

 

You may also proceed downloading the hardware manual from the support site specific to the y50 model. 

Power checkout page on the manual would help you direct on testing the ac adapter to further isolate the issue. 

Battery charging indicator should also light up as ac adapter would be able to charge the battery on a normal power board and systemboard controller. 

 

Update us how it goes. 

 

Regards

Re: Lenovo y50 Adapter Surge

Hello spidey,

   I found that my machine number is 59421855.  As for the hardware manual, I downloaded it and did what it said about removing the battery pack and then plugging in the ac adapter into the laptop.  When I did this, the noise from the ac adapter started again, no lights light up in the bottom left hand corner, and pressing the power button did not do anything.  Unfortunatly i could not check the voltage that the ac adapter is outputting because I do not have the required tools for me to do this.  It seems that the ac adapter is definitely a problem, but is there any way to know how much more damage it caused?

Hi Nozshund , 

 

Greetings.

 

As of now I would not suggest using the adapter further as not to cause further issue with the systemboard not unles that we have a known good working adapter or to further check the original with a voltmeter . 

 

Furthermore , the manual would also indicate battery charge testing as we would assume that without the ac adapter , the laptop would still power on with charged battery.

 

Let us try to observe more when tools would be available or if you would have active warranty to have technical support work on it else have a service center check since they most likely have alternate tools to use. 

 

Update us how things go .

 

Regards

Re: Lenovo y50 Adapter Surge

Hello spidey,

 

   When I try to turn on the laptop with the battery in but no adapter, the laptop still fails to turn on or have any lights come on/show any sort of life.  I believe that my warranty has expired.  Is there a way that I could find where local service center's are and the cost for them as I believe is beyond something that I can fix.  However, I know someone who would allow me to use their charger tomorrow, meaning that i could do a few tests to see if it is just my charger that has gone bad, or if it is the laptop itself.

Hi Nozshund , 

 

Greetings.

 

I do hope that it would just be an adapter issue as systemboard failure may be costly. 

 

If ever it did not worked with another adapter , you can have it checked in nearby best buy shops as they would also have their technical team that are trained with Lenovo systems and would be able to estimate pricing for you. 

 

Power boards and cable chcking can also trigger this symptom as cheaper than the motherboard. 

 

Update us as soon as convenient.

 

Regards

Re: Lenovo y50 Adapter Surge

Hello spidey,

 

So I was able to check what happens if I used another charger than the one that I own.  When I plugged this new one into my computer, interestingly enough the adapter started to make the same noise that my adapter was making, even though the new adapter never made that noise before and still chargers on my friends y50.  This makes me think that whatever has occured is most likely a systemboard failure.  I hopefully be able to take it to a best buy/ computer repair store soon and see what they have to say.  Thank you for all the help that you've been able to provide!

Re: Lenovo y50 Adapter Surge

If you use your notebook from a fix location the majority of time its best to have either a good quality Surge Bar or surge brick which plugs into the AC outlet. You'd be looking also for surge ratings of 1000 Joules or more with serious clipping spec's. Name brand makers have various products. EG: Tripplite, APC, Belkin to name a few.

Re: Lenovo y50 Adapter Surge

I had the exact same issue but I bought a new charger and the new charger doesn't have the ticking noise and the battery indicator is working. However, it won't turn on even from a hardboot the light goes on and then goes off. Did you get yours fixed?
