qiweiyu11 Posted July 14, 2016 Share Posted July 14, 2016 Hey guys, i just updated my P151em with a new 980m. Everything was okay but since couple days ago, everytime I play 3d games , there is always some buzzing sound coming from my laptop. And when I go back to desktop, it will immediately stop. I found that many desktop 900 series cards have this issue but never heard about mobile version having this issue. I am wondering if anyone else has the same issue with me and if this issue will damage my card. Thx! Quote Link to comment Share on other sites More sharing options...

Breakbeatnik Posted July 14, 2016 Share Posted July 14, 2016 Have that issue when the laptop (p771zm+980m) is only running from the battery. It solves when I plug the AC PSU. some older games make it louder too. might be related with fps and power drainage. Quote Link to comment Share on other sites More sharing options...
Khenglish Posted July 14, 2016 Share Posted July 14, 2016 The sound is annoying, but other than noise its nothing bad. Quote Link to comment Share on other sites More sharing options...

I think it might be becasue the power consumption of 980m is beyond my power supply circuit or PSU , which I have 180w right now. I will try 230w later and see if it will be solved. ( But I heard there is a power limit in P151em. ) Quote Link to comment Share on other sites More sharing options...
