My AC adapter stopped working. The charge light will flash on for less than a second then shut off. I recently downloaded SmitFraud, and rebooted in Safe Mode, cleaned out my system, and it was after this that it stopped working. Any thoughts or should I just buy a new cable?

Re: AC Adapter stopped working
SmitFraud is not capable of doing actual hardware harm. It can be a pain to get rid of it software wise, but it can't do any harm to the physical machine. I think you've just had bad timing with this problem.
If the charger isn't charging, there's one of two problems. Either the charger itself is faulty, and it's not thinking the battery is charged when it isn't, or the battery is faulty. I would personally take your laptop into a shop that sells the same kind, explain the problem and ask if you can plug one of their adapters into your laptop. If the light comes on and immediately goes out, it's the battery. If it comes on and stays on, it's your charger. Either way you can find out which it is before you have to spend money on a replacement. Do be sure to do it with the shops permission, though - they won't like it if you help yourself, and you might find yourself swiftly banned from the premises.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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?
Remove the battery and the Charger or AC Adapter as well call it from the G550 then press and hold down the power button for 10-15 seconds to drain power from the system motherboard.
Once drained connect the AC adapter but do not connect the battery yet, then turn the Laptop ON to see if the system will power ON using the AC adapter/Charger if it powers up then there is no problem with the AC adapter/charger.
After testing the AC adapter if it is working power down the Laptop doing a normal shut down.
Once shut down or turned Off insert the Battery back in the Laptop then turn the Laptop ON using the battery only without the AC adapter/charger see if the system will turn ON using the Battery only.
If the Laptop powers On using the battery alone with out the AC adapter then the battery is most likely working as well on the issue.
Now power down the Laptop then connect the AC adapter to the Laptop with the Battery in the Laptop as well then turn the system ON again see if the problem will Occur again having the battery and the AC adapter/charger if the Problem happens with both Battery and AC adapter on the Laptop then the problem is the Motherboard, most probably the motherboard is having issues relaying power from the AC adapter to the battery and may be sent to the Depot for repairs.
I suggest that you call Lenovo for further information about your system, if you still have warranty and is still in the one year period then your system will be covered for any repairs needed - you can call @ 1 877 453 6686 for troubleshooting, you will be asked for a serial number Located underneath the Laptop on a small white sticker that states s/n meaning serial number.
Remove the battery and keep the battery unplugged.
Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
Normally power on the notebook.
If the unit does not power on, remove the ac adapter and insert the battery into the system.
Plug the ac adapter back into the system, the battery charging indicator light will light up. If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Try removing the battery and see if the laptop works with the AC adaptor. If not either the AC adaptor is bad or the motherboard is defective. If your battery LED flashes (yellow or Amber) or is solid Yellow or Amber color, this usually indicates battery is beginning to go bad. Eventually it will not hold a charge and will need to be replaced. As for the error message “failed DST short test 1000-0146”, this is flagging an error on your hard disk drive. This could be caused by a bad hard drive or just needs to be reformatted. Your responses are intended to improve the level of service provided.
