Question about Lenovo G550-29583AU Notebook
The battery is charged- the power is on - the hard disc indicator light flashes on initially and then goes off- the screen stays black
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.

try removing the battery and removing the adaptor press and hold down the power button for 5-10 seconds then let got this will power drain your system board noy turn the system on using the battery only without any adaptors to charge or power the system, try turning the system on if the system turnes on leave it turned on for a couple of hours then conenct your sysem adaptor monitor if the battery light and the battery indicator on the lower right of the screen in windows woll indicate that the system is chargin if it is then I believe everything should be fine the blue indicator is for your system if it is blue then your system is turned on and has power if it turned orange and blnking then the battery will be more likely be almost out of juice or may need charging.

For your G550 issue that no display will show on your screen after turning it on although all the lights are showing there are different reasons why you're getting this issue. The two most common issues are:
(1) The system just needed to be refreshed and reset the BIOS. Don't worry because resetting BIOS is just easy and you can do this on your own. Simply power drain your machine.
Here's how: Shut down your PC >> Remove the battery and unplug AC adapter >> Without any power source press and hold the power button for 15-20 seconds (nothing will happen yet) >> Put back the battery and the charger >> Then, turn on your PC.
(2) The LCD cable from your screen going to the motherboard is loosed, that needed to be repaired or defective, and it needs replacement. For this one, you may contact Lenovo to give you options about the repair.
Well, in some rare cases screen might be also defective and needs replacement. You may also take a look on that possibility.
Hope this helps.
Thank you for using Fixya.

I see you are having issues with you G550 charging.
You mentioned that the light on the charger is lit up but then it suddenly switches Off, and you also mentioned that the charge still has a light but the power is somewhat low despite of a fully lit up charger Light.
Have you tried draining the power from the system?
I hope that this Helps.
Have a nice day,

you boot up to the log in screen type in administrator as user to log
in if you cant log in
the boot up process you will see on the screen for a short amount of time press
a certain key to enter set up press and
hold that key during the boot up process to enter BIOS scroll down to set user
password or supervisor password you can change or remove your password from
most common way that we know on how to reset or clear the BIOS password is to
physically remove the power from the computer by disconnecting the power plug
and then removing the Cmos battery for 30 minutes from the motherboard. Another
way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2
methods mentioned works because most motherboards use a battery to sustain the
BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the
battery power, the BIOS/CMOS settings will be erased. Hope this helps
