someone gave me old Toshiba Satellite L505D , it has the following problems:

all usb ,touchpad,keyboard don't work ... whether in windows or even in bios..
the usb is dead..won't get any flash usb stick or mouse or usb keyboard to work... no light coming out of the flash drive or mouse...
keyboard won't work ,with the exception of FN keys... when i turn it on and press F2 it gets the bios... and on the bios i see the clock and date working ,but i can't go anywhere on the bios because no other buttons on the keyboard work,except the FN keys !

I took off the CM battery of the motherboard ,but it won't change anything except resetting the date...
I disconnected all the usb cables and the keyboard then reconnected them ..and nothing changed..
i took out the hard disk , installed another windows 8 ,and then coneected it... still the same... laptop would boot till windows and can't do anything else ....

any idea

thanx

You seem knowledgeable and it's almost 10 years old. Perhaps just stripping it for parts to use in other units or to test with might be the best outcome.

I would like to add

when I turn on the laptop ,if I press "Caps Lock" key. the light of the key turning on and and if I press off ,it turns off... but after i press f2 to go into bios ...in goes there to the first page..and I see the clock working changing the time etc... but no up and down ..and even I can't change the caplocks from on to off or vice versa..

so I guess the keyboard is fine till the laptop gets into bios ....

idea? corrupted bios? but if that is true how could I flash it..if I can't use any usb ,or any keyboard?!! inside or outseide windows !!?

anyway to flash bios without usb ?

or flash it inside windows without keyboard or mouse?

that is the only choice left I think

If the unit has A:(Floppy) or a built in CD drive (obviously not a USB one since the unit's USB is kaput) then something like this could be used: https://www.wimsbios.com/awardflasher.jsp
If you fry the laptop, it's not a big loss.

thanx

the unit has built in CD drive ,and I did your advice and flashed a new bios,but the problem persists !!

now the dilemma ..whether it is a motherboard problem or keyboard+usb ports+touchpad ?

if the motherboard scenario is true,why the motherboard identify the cd drive ,rams ,hard disk ,the clock is working ?

if the keyboard+usb ports+touchpad scenario is true ,1- seems strange to malfunction all the three simply like that ! 2- why the keyboards works immediately after turning on the laptop and stop responding ,immediately after I click f2 ?

thank you corday

just one update:

1- I tried to stick usb flash memory to both the 2 usb ports..and I noticed ,that when I put it all inside the port and move it a little backward ..the flash lights for 2 seconds ..but then the light gets off again ,with no sign of hardware identificaction on windows... if i stick it out and put it again,moving it in and out slightly ..happens the same thing exactly !!!

I put a usb mouse ..but it would never flash light whatever I do...

Ports might be worn out.

Desktop bare, Task Manager absent
So, I'm having a bit of a problem here. I turn on my computer, it works fine. I log in, see my desktop and all my beautiful little icons, then after a second or two they all disappear, as does the taskbar. A little bit after that, I'd estimate four seconds later, a white fullscreen window...
