Laptop Not Plugged In ¶
Make sure the laptop is plugged in and/ or the charger is connected, so that you can ensure the computer has a charge.
Faulty Battery ¶
The battery may not be correctly connected to the laptop. If this is the case, the laptop will not charge and therefore not turn on. Check the repair guide for instructions on how to access the battery

Broken Trackpad ¶

Software Out Of Date ¶
Out-of-date drivers can be checked by going to the Toshiba support page, searching for drivers by model number, and checking for driver updates. This can also be done in Windows by checking for system updates. This will check the web as well. Install any available updates.
If the above is not the issue driver interference could be the root cause if the problem started around the time you installed another input device like a wireless mouse. In this case, uninstalling the other driver from the 'installed program' list should fix the issue.
