Restarts, system hangs or slowness

It can be due to several factors that must be deducted depending on when the problem is observed.

2. Software problem with which it is necessary to reinstall the firmware or Windows as explained in this manual.
3. Slowness during the use, it may be due to the fact that we have several apps loaded in memory, we can restart and compare or with the Windows task manager or an app manager app to control the problems in use.
