Toshiba Satellite C55-C5268 Troubleshooting
- Keys/keyboard won't respond
- Toshiba Satellite doesn't power itself (Battery isn't working)
- CD/Disk drive does not work
- Toshiba Satellite begins overheating
- Exterior attachments (mouse, USB drive, etc.) not connecting through USB port
- Will not connect to Internet, wifi, etc.
When you press a key or keys , nothing happens on the screen, there is no response or the key is jammed.
Sometimes people can accidentally lock their keyboard. This makes whatever device they are using not respond to most keys being pressed. However the special keys usually don't lock so this can be undone. Each brand or model can be different but most use Ctrl+Alt+L to lock and unlock the keyboard.
Sometimes a key can become jammed and need to be removed and cleaned underneath. Other times it is broken and needs to be replaced with a new one.
If the Toshiba Satellite is handled roughly the keyboard can become detached from the motherboard, therefore becoming unresponsive.
The keyboard may need to be replaced if it is attached to the motherboard and still not functioning properly.
The device won't power on or only powers on and runs when plugged into an outlet.
A charger would have been included in the purchase of the Toshiba Satellite. Plug the corresponding end into a working outlet and the other end into the Satellite. Wait a few minutes then try powering the device on.
Sometimes an outlet doesn't work properly or a fuse is blown and people don't know this. To test this take a device you know works properly (like a lamp) and plug it into the outlet. If it turns on the outlet is fine, if not the outlet is broken or not receiving power. Also be sure that the charger is plugged all the way into the outlet and laptop, and that it is connected in the middle.
The battery may be where its supposed to be but not properly attached to the Toshiba laptop to power it. It may need to be removed and reattached to the Toshiba Laptop.
If the battery is attached properly then it may not be charged. You may need to plug it into a charger and let it charge.
The charger may be faulty if the Toshiba Satellite has the battery installed and is not charging. If you have another charging device that fits the port, test this by using the other charger. If the 2nd charger works the the original is faulty and needs to be replaced.
If the previous problems aren't what is causing the Toshiba Satellite to perform improperly then the battery may need to be replaced. To replace the battery go to the following replacement guide:
The drive won't play the disk that is inside it or will not open.
Sometimes it is not the disk drive but the disk that can not be read. To test this try the disk in another device. Or try a disk you know works in the disk drive. This will help solve or narrow down your problem.
The disk drive is not spring operated therefore it needs power to open and operate. If the Toshiba Satellite is not on the disk drive will not respond or operate. Make sure it is on.
The disk drive is most likely broken and needs to be replaced if the laptop is on and it doesn't respond. To do this follow this Disk Drive replacement guide:
The computer can run slower, crash, or power off when the device gets too hot. These things are all signs that the Toshiba Satellite needs to run cooler.
If the Toshiba Satellite isn't able to ventilate the heat from the inside, it can easily overheat. Placing the laptop on a surface like a couch cushion, blanket, pillow, or even your own lap can block the the ventilation on the bottom and sides of the laptop. Try to give these areas a little space and make sure they are not pressed up against anything. There are thin long holes on the sides of this device, where you can feel the heat escaping, make sure these are not blocked.
The heat sink transfers heat from inside the device to outside of it. If it is covered in dirt, dust, or anything really, this will cause the heat to be trapped and overheat the laptop. To clean the heat sink follow this guide:
If cleaning the heat sink and creating open ventilation airways does not fix the overheating problem, the heat sink is broken and will need to be replaced.
When plugging an exterior device into the Toshiba Satellite USB port it does not connect to the device and exterior attachment does not work or connect to the device.
When plugging an attachment into the Toshiba Satellite, it could be the attachment that isn't working. To test this plug the attachment into another USB port on the device, there are 3 in total. If none work it is most likely the attachment. To be safe plug a different attachment in or, plug the original into another device.
Often times an exterior attachment being plugged into the USB port will be put in upside down. Flip it around the other way and make sure it is in all the way or it won't properly attach to the device.
Dirt, dust, debris etc. can get stuck in the USB port which can prevent an exterior device from attaching to the Toshiba Satellite. Cleaning the USB can often solve this problem.
Some USB ports do not connect directly to the motherboard and the Toshiba Satellite has one of these. The ribbon connecting the USB port to the motherboard may need to be reconnected.
If cleaning the USB port does not solve the problem then it is most likely broken and needs a replacement. To remove and replace the USB port use the following guide:
The laptop won't connect to the internet or any wireless devices.
Sometimes the router needs to be reset. This can be done by unplugging the router or modem for 30 seconds then plugging it back in.
The LAN card connecting the laptop to the router or modem may not be working properly. If resetting the router multiple times does not fix the problem after a day or two the LAN card needs to be replaced.
