Asus Laptop charger light blinks

Question:"I was using the computerabout 5 hours ago. Then i fell asleep and when i woke up my laptop was shut off and the battery charger was blinking, but when I unplug the the asus x53e adapter from the laptop it stopped blinking and turn solid green. So when I plug the charger it starts blinking. I already took out the battery and still blinks when I plug the asus laptop charger. Is it my laptop? the charger? or the battery?"
Solution:
"Try unplugging the power brick from the wall and let it cool down for a couple hours then try plugging it in and turning it on WITHOUT the battery. If it comes up, let it boot then shut it down before reinserting the battery. If it still doesn't work, try a power pack from another laptop with a similar plug, just make sure that the voltage is the same (or close) on both power packs, the voltage will be listed on the unit. Most power packs are around 18 or 19 volts and will work on several models.
EDIT: Does the laptop boot up and function with the battery removed?
If so, did you ever try a different power pack?
Of course it won't charge the battery i f i t ' s r e m o v e d .
Don't do what spamming idiot David below me says. The link he provides is nothing but adware/malware/viruses and it will screw your computer up.
P.S. Try a different power pack already!'
"If your DC jack isn't loose and looks normal, I'm guessing it isn't the problem, but you might still want to try it if you don't have other options.
1. It's a bad sign for the motherboard if your asus laptop AC adapter light blinks only when you plug it into the notebook since it also tells me something is shorting out on the motherboard.
I would try to first get your AC adapter light to stop blinking if possible by unplugging everything you can and making sure there isn't something else causing the problem.
Or, if you can easily remove the motherboard, plug in the Asus VivoTab TF600 adapter to confirm the light is still blinking with only the motherboard (put the motherboard on a non-conductive surface, of course).
If the asus U38DT adapter light stops blinking when you plug it to only the motherboard, you can try to slowly reassemble the notebook and hopefully catch the problem/problem part.
If the problem appears to be with the motherboard (my guess), it may not be easy to fix, but inspect the board for any damaged/burned (easily replaceable?) components, etc. that could be causing the problem.
Well, I'm not all that familiar with repairing motherboards since we usually just replace them over here, so you may want to get more opinions about it if necessary.
2. You may not be interested in going this route, but if you didn't already know, just wanted to remind you that you can contact U.S. ASUS support about sending in the notebook for out-of-warranty service if you prefer by checking this contact page.
If you decide to send it in, try to make sure parts are still available though and find out what happens if they aren't.

3. You may be aware of this already too and everybody is different, but personally I don't like putting too much money into an older out-of-warranty system and would prefer to save for a newer (faster) system with warranty if possible. If you didn't already know, there are ways to connect your hard drive to a different system to access data if this makes any difference."
