Toshiba Satellite C650D Troubleshooting

The Toshiba Satellite C650D is a large laptop that grants easy access to the RAM and hard drive areas. The laptop is known for having issues with remaining charged and overheating. This wiki will offer solutions to these problems, as well as a number of others that may arise.

Computer will not turn on

The computer does not show any sign of powering up. Make sure the power adapter is plugged into the power source and computer.

Damaged adapter

If the light on the adapter is not on and the computer is not showing any sign that it is charging, then the adapter is damaged.

Damaged battery

If the computer only turns on when the computer is connected to the power adapter, then the battery is damaged, and needs to be replaced.

Lack of key response

The keys on the laptop are not responding

Keyboard is damaged or disconnected

If the keys do not respond, the keyboard may be damaged or disconnected. To check the keyboard connection, follow the disassembly instructions in the keyboard replacement guide. If the keyboard is properly connected, but the keys are still not responding, then the keyboard should be replaced.

Dirt or residue under the keys

If single keys seem to stick, it could be due to dirt or residue under the keyboard. Make sure the computer is turned off, and then clean around the sticky keys with a cotton swab soaked in rubbing alcohol. If this does not solve the problem, remove the keys with a thin, flat screwdriver to clean them and their surrounding area with the alcohol.

No display

The laptop turns on, but the monitor is blank.

Broken screen

If the screen has noticeable black spots, the appearance of a “ripped” screen, color changes, physical cracks on the screen, or a total lack of visual response, then the screen may be broken.

Display is disabled or powered off

If the screen is black and unresponsive (it looks like the computer is turned off, but there are lights on the laptop indicating that it is powered on), the display may be disabled. To enable the display, press and hold the (Fn) key on the keyboard, then press (F2) while holding the (Fn) key. The display will re-enable, if it’s not broken.


While the computer is working, the bottom gets hot and makes a lot of noise.

Dust inside the fan

A lot of dust in the fan can make is spin slowly, and make the computer overheat. Use compressed air to remove the dust.

Fan is broken or disconnected

If the fan is clean, check the connection by opening the computer and making sure the connections look like this. If the connections are fine, then the fan is broken. Follow the replacement guide, found here, to solve this problem.

Loose internal insulation

The computer may have loose internal insulation. Purchase thermal paste and apply it around the main processor to seal the area.

Hard drive error

After powering the computer up, if it appears that your profile has been deleted or you get messages about the system detecting a ‘critical error’, then there may be a problem with the hard drive.

Hard drive is disconnected

If the computer will boot, but will not let you access files, restart the computer. If this does not seem to work, make sure the hard drive is properly connected.

Hard drive is damaged

If documents lose information or are altered, then the hard drive could be damaged. Remove the hard drive and replace it using the procedure outlined in the hard drive replacement guide.

Computer is slow, crashes, or will not boot up

If your computer is slow, crashing during normal operation, or will not boot up, then there may not be enough RAM installed, or some RAM may be loose or faulty.

RAM is dirty

Follow the steps found in the RAM replacement guide to carefully remove the RAM. Clean it with a q-tip or fine brush, and once cleaned, replace it in its slot. If the RAM still does not work as needed, then you should remove it and purchase a replacement chip.

Need more RAM

If your computer is struggling to perform standard operations, such as browsing the web or creating text documents, or it becomes noisy and whirs more frequently than usual, then it may need more RAM to speed it up. In the event of a slow/struggling computer, purchase additional RAM.

RAM is loose

If the computer seems to run fine, and then suddenly slows down, the RAM may be loose. Follow the RAM replacement guide to access the RAM, and then secure the connection.

RAM is faulty

If the Ram is faulty the computer will run slowly and crash. At this point, the only option is to purchase additional RAM. Follow the RAM replacement guide to do so.
