if its more serious I am not going to pursue in fixing it, it is not worth the effort to fix if it is going to cost more to fix it then how much it was purchased for I will use it for parts that are still good

It all depends how much someone will estimate for what's wrong and how much you paid versus what a similar or better rig is running now. I think it could be worth up to 50.00-60.00 to find out what's wrong....but that's your call. Does this mean you can or can't get it bios? I still haven't heard from you on that????

When was the last time you opened it up to clean and look around? I would as you have nothing to lose.

I thought I had posted back in this thread but it could have been a different I suppose.

Now if the HDD has been tested out and checks out ok then maybe it needs good clean out and this site is one I use all the time for fixing Toshibas Toshiba laptop DIY disassembly instructions
Now if you decide to check it out then make sure you read THOROUGHLY the first page as in link as there are important features such as how to work the ribbon cable retaining lugs which can be easy to break or damage the cable if not undone properly.

The disassembly page you need is Toshiba Satellite L455 L455D L450 L450D disassembly - Page 1


TAKING APART LAPTOPS

I always spread out a large white bathtowel on the work top and using cloth or ordinary duct tape keep to be stretchedout fixed down to the work top. This isbecause when removing the sometimes very small screws it stops the screw form beingdropped onto a hard surface where it almost always will bounce and even land onthe floor never t be seen again. Of course if that happens you can scour thefloor with a strong magnet in the case of steel screws the brass ones (thereare some that have brass screws in certain spots) unless brightly coloured youwill not find especially in carpeted floors.

I prefer to use a battery drivenslow speed screwdriver as in pic and leave the screwdriver bits stuckonto a strong magnet or stroke then longitudinally to magnetise them it makeretaining the steel screws so mucheasier especially when replacing them. (If you drop on into the machine youwill need to completely disassemble it again to remove it)

It is also advisable to keep thescrews in separate containers as they will be of different sizes and locations

GENERALINFO

As a general rule of thumb toreplace the thermal compound in a laptop there are two areas to be concernedwith that is the CPU and the GPU (graphics) see pics of them before and afterremoving the heatsink assembly. How you apply the compound is your choice Iprefer to use a cleaner and prepsolution as in the Arctic cleaning kit -http://www.arcticsilver.com/arcticlean.htm and the compound from Artic - http://www.arcticsilver.com/as5.htm but the choice of compound isyours.

To make the job easier because thedies are very shiny I prefer to clean with solution 1 then prep with solution 2 then use a vinylglove and spread a very thin layer / smear on the heatsink and the die – thenadd a tiny half grain of rice size dot of compound the the centre of the die/sand reattach the heatsink assembly. DO NOT apply more than that.

DO NOT over tighten the retainingscrews / bolts

Oncedone and before you reassemble now is the best time to make sure the “radiator”and fan assembly is clear of dust and crud (stuck on dirt).

TIPIf you use compressed air to clean the dustfrom the fan DO NOT let the fan spinit is not designed to spin at speeds exceeding what it was meant to and will ifleft spinning with the air blast will wreck the bearing. If the fan is tight toturn then it needs replacing as the bearings are usually sealed.

PersonallyI attach some fine fabric over my air intake when done to catch the largerrubbish see last pic.

TOSHIBAS

When posting system specs (orordering specific Toshiba parts) it is always a good idea to include the PARTNO as seen in this pic



Taking the machine apart is easilydone but as in this pic it is advisable to make particular note of how toremove and replace the ribbon leads.


PS Sorry about the pics they wouldn't load
