Toshiba Portege R835-P88 Troubleshooting
Released February 2012, model number R835-P88
The screen stays black when the power is on.
Check to see if the battery works with a multi-meter. Plug the battery up and see if it holds a charge. If you have a spare battery plug it up to the device. If the battery was the problem the screen should come on.
If the screen itself is broken check for cracks and looseness. Dust and debris could also be inside the device keeping it from working properly.
The problem could be the device is not charged. Plug the power cord into a wall outlet and give it a little while to charge.
Turn the device off by holding the power button down for 60 seconds. Next unplug it and remove the battery. Plug the device back in and press start. If this does not work try a few times. If still not successful the motherboard may be bad.
Laptop is overheating . Turn the device off and let it cool down for awhile. If laptop is still overheating when turned back on the cooling fan could be dirty or not working at all.
Fan becomes noisy and perhaps makes a grinding sound. Remove the fan and clean it thoroughly. If it's still making noises, replace the fan.
If a DVD drive refuses to read CD's but will read DVD's, or vice versa, the most likely cause is that one of the two read lasers has failed. Replace the drive.
The disc will not come out of the drive when you click the eject button on the screen. Press the button on the optical disc drive itself. If it still does not slide out, make sure a program is not accessing the drive and preventing it from ejecting.
