Solved Laptop won't turn on.

Asus X55c-si30202m black 15.6" notebook...
December 10, 2013 at 08:57:51
Specs: Windows 8, intel i3 2.3ghz
Laptop won't boot up, black screen, battery light and charging light on, no hdd light, fan on. How do I fix? When I purchased this laptop I put a boot password and an admin password in the bios, due to using it for school and carrying it around everywhere. I later decided that I didn't need the password, so I went into the bios, removed it, and upon rebooting nothing happened. No screen activity, no hdd noises, only thing is the fan will come on after a minute or two, the charging light comes on when I plug it in, and the battery light comes on. I've already checked the hdd and it works, I've reseated the cmos battery, to no avail. I bought this thing in September 2013, so it's brand new, unfortunately the warranty is now void do to me having to take it apart. Also another thing to note is that the RAM is not loose or unseated or anything, due to the fact that it's part of the motherboard. Any suggestions on something I may be overlooking, or something way out of my league? Any help is appreciated.

Sounds like a motherboard issue - ac adapter/battery is providing the system with power but it is not being distributed to the system. Get it fixed if under warranty, otherwise you've got a hard decision in terms of whether you want to shell out for a motherboard or buy a new PC.

Seems pretty clear that your password activity caused this. Not sure what you did but usually you have to enter your old password in order to remove it. If you can get back into BIOS then the password needs sorting out there.

Always pop back and let us know the outcome - thanks

That's one of the problems, I can't get into the BIOS because the computer won't turn on. It's almost like a paradox.

Your BIOS password changing may be responsible but it's pretty unrelated to power distribution in your computer.

First thing to do is check the color of the power button on your computer when you turn it on. If it's anything other than solid green, chances are something is wrong with either your power input (ac adapter or battery) or the power distribution (motherboard). A solid green power button is how it's supposed to be when turned on correctly. If it's not solid green, find another computer and google your computer manufacturer and model and the color of your power button, you should find a link to the manual that will tell you what's wrong with the power and what exactly you need to replace.

Assuming your power button is solid green as usual, you can rule out power issues and (if you have it) attach an external monitor to your laptop and see if you get an image on it. If you do, you need to replace the monitor on your laptop. DO NOT ATTEMPT TO DO THIS YOURSELF UNLESS YOU 100% KNOW HOW. The wires are extremely small and easily breakable, and worst case scenario you break the monitor and the LCD crystals spill out - these cannot be replaced with anything sold in a retail store - and worse yet they are made with chemicals that may have a reaction with your skin if you get it on your hands.

If you don't get an image on your external monitor, you'll have to replace your graphics card or motherboard if your graphics card is integrated onto the motherboard. Better to just replace the laptop in that case as you can buy a new laptop for the same price as a motherboard assuming you aren't purchasing a fancy gaming laptop.

Other things you could try for free: Try a different wall jack. In rare circumstances your wall jack isn't getting sufficient power to your laptop if it's plugged in - and if it's a problem with your wall jack then call your electricity provider and have them take a look at the wall jack (or you may have to call an electrician). The power grid in 1st world countries is pretty stable compared to the rest of the world, but even so it has flaws sometimes. Also, try a different electrical appliance in that wall jack. If your laptop is plugged into a UPS or surge protector, try plugging it directly into the wall and see if that makes a difference. If it powers on, you'll have to replace the UPS or surge protector. If you're using an ac adapter other than the one that came with the computer, double check the wattage on it and check with the manufacturer to make sure the wattage requirements for the computer and the wattage of the ac adapter match up.

If you can rule out issues with the graphics card, try an alternative ac adapter if you've got it - also make sure you power on the laptop with just battery and just ac adapter, not both in the system together as you normally would. If you don't have spares of either, I would recommend buying a 2nd ac adapter to try first since that will be both cheaper and easier to obtain.

Check with your manufacturer to make sure these parts are under warranty, you could get both for free if they are. Batteries are known to have a short life, though, so most batteries won't be covered even under the system's extended warranty.

Hope that helps.

Yes that is very true - could just be a wicked coincidence I suppose.

The power light remains a solid green constantly, and the battery light stays orange until it becomes fully charged, at which point it turns to a solid green as well. There's no image on my monitor, or an an external monitor. I've tried 3 different outlets in my home all three to no avail, and I've also tried turning it on with the battery and no charger, with the charger and no battery, and no battery no charger and de-energizing it hoping it was only in sleep mode.

When the laptop is turned on all the lights including the hdd light come on for a very brief moment and then cut off, leaving only the power light, and the battery light on. Also when it is turned on the only hdd noise is as if it's barely moving atfirst just getting power, then goes quiet. The fan runs continuously once the laptop gets warm.

This will probably sound crazy and probably won't help, but at least it is easy to try:

Turn off, unplug the domestic power and remove the battery. Now hold the power off/on button in for about 20 secs. It has been known to fix certain lockups.

Just tried it, still to no avail. This thing sat under my bed with no power for about 2 months after I got frustrated trying to fix it. This is my return to battle.

Thanks guys, I guess I'll just write it off as a loss and get a new laptop. I appreciate all your guy's help though. :)
