There may be too many programs running at the same time and insufficient memory.In terms of configuration, Y400N is more than enough to play League of Heroes.
Did I disable the independent graphics card? Look at the display settings in the control panel. The high performance independent display is used globally. What's more, I don't know how much memory you have. It may also be insufficient!
Don't plug in the power supply? If you want to play games, plug in the power supply. Otherwise, the battery power is not enough, or you will definitely get stuck!!!
Check the network speed, and then see if the independent video card is working. Check the temperature of the machine. If it is not feasible, try restoring the system version.
I guess there is a virus in your computer, or there is too much garbage. Please clean it up.Clean memory+antivirus+defragment.It's a failure to re install the system
This configuration should not be stuck. Use the hardware master software to see the utilization rate and temperature of each hardware. If there is no problem, it is probably the problem of network speed. How many megabytes of broadband?Is it over 8M?
There is a problem with the quality of the notebook.I have a new HP computer in that company.Some computers are stuck.Later, HP engineers came down to check, and the result was a hard disk problem.
