Hi, I'm using hcl laptop. When i make my laptop in sleep mode entire network of my office goes down. Plz tell why its happen and how to fix this issue.

Hi, Firstly, I would like to verify what kind of error message was received after your laptop in sleep mode? Have you configure the router setting on this computer? What is the network environment? Also, have you test whether the network will not if you turn off this computer? You can try to update your network card driver and rest TCP/IP to check the result. You can refer to How to reset Internet Protocol (TCP/IP) Hope this helps. Vincent Wang TechNet Community Support
