Toshiba Satellite C855D-S5109 Troubleshooting
This troubleshooting page will help you fix problems with the Toshiba Satellite C855D-55109
Laptop getting Hot
The laptop is warm or hot to the touch, and/or the surface it is sitting on is warm.
Dust in Cooling Fan
Dust can commonly accumulate on the fan causing a malfunction. The fan may start producing a loud noise and cause the lap top to increase in temperature. In this case, removing the bottom of the lap top and utilizing a can of compressed air to blow off any dust on the fan will help prevent issue. Removing the back will also prevent the dust from being blown back into the computer.
Faulty Cooling Fan
Set the fan from “passive” to “active” via left- clicking the battery icon in the lower right hand corner. Left click again to see More options. Click the Change Plan Settings button. Click on the Change Advanced Power Settings option. Hit the “+” plus sign next to the Processor Power Management button. Click on the “+” plus sign beside the System Cooling Policy button. Change the fan speed from “passive” to “active” for both the Battery On and Plugged In options. Repeat this for any other modes, like Power Saving Mode, that you use. Restart your computer.
It is recommended that you keep your laptop on a flat surface while in use to help the fans circulate air to keep your laptop cool. Check the fan for any dust as this may also hinder the fan’s ability to function properly. Simply unplug and turn off your computer. Flip it over and unscrew the bottom cover. Check the cooling fan for debris like dust and clear it out. Once clean, place the cover back on and screw it back into place just enough to not fall apart yet not too tight.
As a last resort, you can update your BIOS (Basic Input/ Output System) program to the latest version. If your device shuts off during the BIOS update and installs, the laptop won’t turn on again.
Processing too much data at once
Having too many applications open at once can cause the lap top to over heat due to the computer attempting to keep programs, web pages or any applications running all at the same time. A solution to this would be to close out of as many applications as possible in the event that the lap top over heats.
Laptop Making Loud Noise
You hear a loud whirring or grinding sound emitting from the laptop.
Malfunctioning Cooling Fan
Make sure your BIOS is up to date. Keep the device on a flat surface and out of hot environments. Make sure nothing is clogging the vents. Adjust the laptop’s Power Options to increase Battery Life and reduce performance; this will help keep the laptop cool.
You may need to replace the cooling fan.
Cooling Fan Replacement:
- Power off your device. Unplug your device if it is plugged in. Remove/disconnect any other cables or cords connected to your laptop.
- Open the laptop screen as far as it will go without force. Taking a flat head screwdriver, gently pry open the keyboard cover. Remove the cover and set it aside.
- Remove any screws holding the keyboard to the devices’ base. Lift the keyboard and gently bring it toward you until it is resting face-down on the wrist-rest and mouse area. Carefully disconnect the ribbon wires (attached to the keyboard) from the system board.
- Remove the screws securing the fan’s shield in place and set the shield aside.
- Remove the screws securing the fan to the system board. Lift the fan’s cooling can (a large piece of metal that sits atop the CPU) from the laptop and unplug the fan’s cable from the system board. Set the fan’s cooling can aside.
- Install the new fan by repeating the steps above, in the reverse order.
Laptop Dying Immediately
