My daughters Toshiba satellite l505d will not boot up correctly. It starts but then nothing happens. What do I need to do. Have already taken battery out and restarted. Any help would be helpful.

Try the following.
1. Remove battery and plug in the AC Adapter and check if it works
If yes - Battery is defective
If no - Motherboard Problem/AC adapter

2. Check the AC adapter LED indicator if its lighted or not(double check by a multitester)
If lighted - it works properly
if not - replace
3. Try to reinstall WINDOWS operating system by the use of the installer CD
4. Reformat your computer and install necessary drivers and applications

Thanks. Cheers!

If Laptop Will Not Start Up (Power, Battery, AC Adapter LEDs ON, NO Hard Drive Activity LED, NO Display, NO F2, ESC, etc)
Power OFF Laptop
Unplug USB Laptop chiller fan
Battery is installed
Plug-in AC Adapter
Power ON Laptop
Wait 15-60 minutes!!
Power OFF Laptop
Unplug AC Adapter
Power ON Laptop (Laptop should Start Up!)
Plug-in AC Adapter
Plug-in USB Laptop chiller fan (Laptop chiller fan required otherwise CPU will overheat and HALT system)
Above steps have worked every time my Toshiba L505D-GS6000 Laptop would not start up.
