Lenovo U410 - Wifi disconnected when connected to USB.



I bought a Lenovo U410 sometime in July 2012 (bought it back home in Malaysia). About a week or two after I bought it, the laptop sleeve cover came off, causing the laptop to fall to the floor. But fortunately, other than a small dent (pictured) at one corner of the laptop, everything seems to work okay. [well, if you plug in an earphone, only the right side would play but I'm not too concerned about that]


I've enjoyed using the laptop, everything works fine & easy for me. I use it mainly for my studies (I'm a rising junior in Madison) and occassionally some photos & video processing. Other than The Sims, I never actually used my laptop for 'gaming' stuff (was planning to soon though).


But recently, in the past few months, I realized that there's something wrong with the laptop. It connects to WiFi just fine and everything, but whenever I connect my external hard drive to my laptop, my Wifi would disconnect automatically & wouldn't reconnect until I remove the hard drive. This happen even when I connect a USB port to the laptop, but doesn't happen when I connect a small USB pendrive or my phone (Samsung Note 4) or a bluetooth speaker.


Not sure what's the problem with it, and I'm a noob when it comes to things like this, so I would really appreciate your help.


Thanks in advance!

Hi syazanazura,


Welcome to Lenovo Community Forums!


The Laptop maybe having power issue since the drop.

    You can try opening 

        Control Panel / Hardware and sound / Power Options / Change plan settings on selected power plan / Change Advanced power Settings

       Now look for the Wireless Adapter Settings Make sure not to use the scroll but use the scrollbar to the right

       Open the Wireless adapter setting and make sure that both plugged in and on Battery are set to Maximum Performance.



Let me know if this works for you
