Laptop black screen during boot, then normal in Operative System
I have an Dell Inspiron 9300 and the laptop screen shows nothing during boot (all black). But then after it reaches the operative system login everything magically appear normal.
I can only see the boot process if I connect an external monitor to it.

Hi, you can perform a system restore by accessing safe mode by pressing the ESC button during bootup. Restore system to a time before the problem began. You will need to perform a full virus scan straight after normal bootup is achieved. Hope this helps
What file was it?. Probably a virus or one of those "suspicious" freebies... Well it seem that your file just changed or damaged something in your operative system. You can use your laptop's recovery utility but you are risking to loose your personal information. In the other hand, there's another (but longer) way to try to get things back to normal. Bear with me: If you are willing to do this, remove the laptop's hard drive (make sure there's no battery in the laptop neither a power adapter connected), mount it on another computer (via external enclosure [keep in mind your hard drive is SATA Interface] or via internal hard drive bay on a desktop) and scan it with antivirus/spyware/malware software. Then run a check disk on it.
Sad to say but this would be the only way around if you don't have a recovery disk.
Reboot the computer and keep hitting F8 to enter the recovery screen. Boot into Safe mode, and run system restore (programs-->Accessories-->system tools). Restore your computer to a previous date when it worked properly.
if battery is new and functioning properly(battery) please boot in safe mode by pressing F8 during os starup. and logon as an administrator.
if nothing works out try reinstalling operating system it will solve the problem else update me the ststus.
