Have you made any modifications to the computer lately? (Taken it apart ect?) I had a similar issue with mine. There was a short in the keyboard. I ordered and installed a new keyboard and it has booted up fine ever since.

Try something as simple as checking the keyboard connection, this will require taking the laptop apart though.

3 orange flashes means flat battery. If you have a faulty charger or charger socket on the laptop then the battery wont charge or power up with just the charger connected.

Welcome to Fixya

Sounds like you already have LCD problem. Try to test the issue further. Use an external monitor and plug it to your laptop. If you get a display using the external monitor then the problem is the LCD. If there is no display coming out then the problem is the motherboard.

Thank you for using Fixya!

you seem to have a problem with your lcd display, defective flex ribbon. if you can do open and check it out that would be better. this things really happens because we always need to open the laptop more than ones a day.

Hello,
Symptons like these usually are due to corrupted data file that is why you Operating System is not loading correctly. Normally an OS reinstallation is the fix. You can shut down the computer and press the OKR button next to the power with an arched arrow sign from the computer turned off and it will restore the system to the default, however everything is gonna be wiped out but guaranteed you system will be error free.
Cheers!
