Toshiba Satellite L455D-S5976 Notebook - Answered Questions & Fixed issues

If you are the original owner Toshiba will reset the bios for a fee and it is not cheap, they may include the HDD reset, if not! www.ebay.com type password, or hard drive password. I would check bios password, probably a lot cheaper if you can find the right seller, also check www.download.com some software may be free.

If you're using windows media player its probably because you don't have the right codecs.Try opening the movie with vlc player or MPC-HC.http://www.videolan.org/vlc/http://mpc-hc.sourceforge.net/

I just had the same problem Toshiba L300 updated the bios.....checked and tested all....the board has overheated (cpu) board has dry joints ,error after error can not be fixed .You have a board with power problems on off cpu fan and boot problems ,maybe iets a cap that needs replacement but that might not solve the problem.replace board.

Buy on on eBay.

If your using Windows 7, click the Start Globe and right click on Computer and select Properties. Take a look on the left for Device Manager. See if there is a Sound Controller. It may just need a new driver which can be found on the manufacturers web page.

just were the line is,,press on the screen and let me know what happens.i think it should go away but then come back when you stop pressing.

Sounds like an intermittent power problem.

It's common that the switch that enables/disables wifi gets hit accidentally. I believe, on your model, that pressing the Function Key (Fn) and the F8 key simultaneously is the way to turn wifi on and off.

If your trying to get into BIOS to change settings and you forgot password you have to reset CMOS whitch set system back to default. This physically done inside computer using the jumper pins on south bridge of motherbaord.. Its a little differant on some systems so you will have to somehow refer to service portion of cumputer management inmanual or find access to MFG website for info how to reset CMOS on your system. However there is software you can obtain that you put on a USB and reboot system and tells you the passwords to the computer, but you must be cautious when useing this software exspecially when there is two operating systems installed so proceed with caution if you go this route. Good Luck !

Ed unfortunately it sounds as if the hard drive has failed. Make certian you do not have a CD in the drive and there are no external drives or flashdrives connected also.

Many laptops have a hidden partition with everything needed to restor the computer. Some people burn it to disk and then delete it to make space. Some laptops come with a restore disk. If you have a hidden partition look for start/all programs/Toshiba see if there is a restore option. If not there could be an option to restore from bootup. If so try hitting esc or f1 or f2 when rebooting.

I'm sure it works. Just wear headphones so that you don't get loud feedback from the mic hearing the speakers. Then make sure if there are any physical switches that they are on. Click volume icon click mixer find your mic and uncheck mute

This is not enough information for me to diagnose this problem, but I bet if you could give me some more info I can get you fixed right up! Are you trying to use an external monitor at the same time as the laptop screen? Or just one or the other? How is the desktop screen connected to the laptop? If you get me as much info as you can about what is going on I am happy to help!

if turning it on with no RAM installed doesn't make it beep to indicate no RAM, it's sounding like it is the motherboard that is damaged.If the computer is still under warranty, I'd suggest taking advantage of that warranty to have the motherboard replaced. If not, you are better off just buying a new computer.

Defective motherboard. Buy a new one

1. need new cable connectio screen to m/board2. screen are faulty3. mboard are faulty..check and/or replace any detected problem...mention above.

Try using another ac adapter, sounds like the adapter is failing. You can either ask if one of your friends has the adapter with the same connector and voltage (check that the wattage of the adapter is sufficient) or if someone has a universal ac/dc adapter for the test. If the laptop starts normally wiht another adapter, then get a replacement adapter and you are good to go.

you have a WinLock Virus--Money Pac--Green Dot Payment--Ransom-Ware.Start in Safe Mode with Networking. Down load Malwarebytes, update, and run full scan. Restart to remove files as instructed. Then download Avast Free Anti-Virus, then run Boot Time Scan.If you feel creative, then unhide your files and folders--root directory--users--(user name)--app data--local (clean up and delete all malicious files, folders, and applications). Delete all you can from the "temp" folder (there will be one that you can't delete).Do the same for the --local low-- and the --roaming--. Go to desktop --start--run-- msconfig --start tab--uncheck all but the antivirus--apply--ok--restart. (will stop the "can't execute .dll files").Go back to root directory--program files--delete all non-essential folders, ie; ask folder, sun, babylon, conduit, aro, mcafee, norton, avg/avg2013, etc...Add/Remove programs--Programs and Features. Remove all un-needed programs. You will see remnants of the files that you just deleted, and try to removed them, should come up and say something in the effect..."Program cannot be found, would you like to remove it from this list?" click yes.This solution will not remove anything from the registry, but it is only advised if a complete Format and OS Re-Install is NOT an option. This will make your unit usable enough to get your files, music, and pics save off of the hdd if you do not have the equipment to remove hdd and connect it to another computer.Recommended is a complete Re-Install, then you will KNOW that your files and registry is clean.If you take it to a trusted repair or other person that has tools and knowledge to do this, you will get back a puter without all the junk-ware and bloat-ware that your puter came with when it was new.Just Sayn

the only way to really know the model is too take out the motherboard . im currently going through the same thing i purchased a motherboard online made for this model once i recieved it it was different than the original so instead of just transferring cpu and ram ect. i had to get new stuff all around . also it was a different machine after that ie. stickers on laptop say AMD cpu now its intel basic stuff like that. the model means nothing basically you have to see the numbers on motherboard.
