Hi guys,
I have an Asus X45C laptop about 10 months old. Yesterday I finished watching a movie with very little battery left, so I closed the lid, put it away and went to bed. This morning the laptop won't boot. Of course I charged the battery all the way, and tried several combinations of turning the laptop on only on AC adapter, only on battery, on both; I also tried removing battery and adapter, holding ON button for several minutes, then trying to power up again with only adapter, only battery, or both, all the time the result is exactly the same, so these are the symptoms:
- Screen is completely black, no bios, no beeps, no anything.
- Power and battery lights turn on (they work ok, if I remove the battery, the light shows that, etc.)
- Hard disk light comes on for about 1 second, then off forever.
- Caps lock and num lock are constantly on.
- Keyboard doesn't do anything at all.
- The DVD unit is working: when I turn the laptop on, it will make noises, and if a disc is inside, it will make even more noises, the usual noises that I get when reading a disc. The button for opening the unit also works. I tried powering up with the DVD unit open, and no noises at all.
- No fans at all are working.
- Also tried using an external monitor, no luck.
I really don't want to RMA it, I know it could be a hardware failure, but it could also be an easy repair. Maybe the CMOS battery or something related to hibernation. Caps lock and num lock always on is what really strikes me.
Oh and one more thing. A couple of times in the past, I had to force a shutdown on the laptop so I would press the ON/OFF button for 4 or 5 seconds.. when it did shutdown, as far as I recall, that was it. When I do that now, I hear a very slight beep after doing a force shutdown. I'm pretty sure this beep was not present when I did force shutdowns before.
Any comments are widely appreciated, thanks!
Update: the beep may have been there before, nevermind. One more sympton: closing the lid doesn't do anything, the same lights are on.

This does sound like a hardware failure. Most likely the mainboard but further testing would probably be needed. Send me a email at cl-fred@asus.com and we can try to help you with the issue.

Exactly same problem here with asus k70af ..
it stops before post.. i can hear hdd spinning up then i noticed that all controls flashed off and on and then again . and wont start...
i tried another disks, rams , chargers,, without battery .. i even took out rams and gpu .. and no beeep sounds from POST announcing missing RAM...i literally tried every possible solution or way to find the cause...
even charging light isnt on when battery is in and it is not charged battery ..
to me it seems like there is some power supply or MB hardware problem .... thats my conclusion ..
any new info about this problem?

i have similar problem with my K72JK, if I plug the power cord I ear something like it's turning on (fan spinning and some activity on the hd) but after a second it dies again. If pressing and holding the power button for something like 10 seconds, it starts again (fan and hd) but its in a sort of boot-loop... always black screen and leds on.

I don't think it's a hard drive issue. My ASUS K53SV is doing this right now, after installing a new motherboard; and it's done this before with the old motherboard. One of themain points of this problem is that we cannot evven get into the BIOS of the motherboard in the first place to try boot disks and the ilk. I have a thread going for this, too. In the past I had success with removing the little lithium battery to reset the CMOS, at which point the BIOS worked.
Bleh, I thought ASUS products had a great rep. Instead I'm having to type on a 3DS.

OK this is extremely crazy... I have no idea why, or how?! but... I have the same issue black blank screen on boot.
Trying to recover data from a corrupted file system, windows XP home edition.
I placed server into a Linux based live environment, and once I was finished I rebooted the server. It would no longer POST. The screen would blink once, but nothing would happen. I had been working with the computer trying to repair the file system and boot partitions etc. So I figured that it might have overheated or something.
All seemed lost, and it appeared that I was going to have to take it apart and replace the CMOS battery or something was wrong with the motherboard, but then a friend noticed... that he could very faintly see words on the screen when it was tilted a certain way. Come to find out... some how, for some reason... after the reboot... THE BRIGHTNESS DIMMED ITSELF! Fn key + F6 a few times and bam... nothing wrong with it... *shrugs* good luck guys.

I have the same problem as well. I have an ASUS EEE Slate EP121 and it recently dropped while in a powered state. I assessed the damage and there was none the back panel of the unit just popped off. Later that day when I restarted the tablet it didn't boot, the power LED just turned on, nothing else happened, no fans spinning, nothing on the screen what so ever. I decided to further investigate and attempt a couple of possible solutions. First was doing a hardware reset aka as restoring the BIOS to default settings by removing any tangible source of internal of external power and holding the power for some time, this did nothing to my avail. Secondly, I tried to determine whether the monitor's back-light was working by checking from various angles while holding a bright light above the screen for any faint text etc, but no avail. Thirdly, I tried to determine if the monitor's inverter were broken and I did this by plugging my tablet into an external monitor before power up, but like everything else no avail. And currently I just verified to make sure my RAM is working and/or seated properly, but still nothing. I also removed and reconnected the screen to motherboard to make sure it wasn't broken.

Hi. I have the same problem on an Asus k50af, the computer doesn't boot at all and I tried all the things that others suggested here, except taking the HDD out. I tried to boot from a win 7 dvd and it didn't do anything even though the drive sounded like it was spinning the disc and all.
I had some problems with the video card giving me crashes and BSODs, and also with the battery... And I never fixed any of those errors, I just kind of ignored them and a reboot did the trick. Probably big mistake. Anyway, now my laptop won't boot up and I'm stuck. The screen works, sometimes if I try to start up, the Asus logo pops up quick, but it disappears and the computer just waits.
Hope someone finds a solution.

I have a X401u with the same issue plus a weird keyboard issue.
It took 2 replacement boards and a stupid amount of time to find a temporary fix:
On both cases when i put the new board in it booted successfully into the Windows 8.1 environment. After a few power cycles it did the same again. I have found that if I remove the CMOS battery for 30 seconds, put it back in and switch on it boots normally.
After a couple of normal boots it reverts to the black screen/no post
Accessing the UEFI through the advanced settings of Windows setup (ran shutdown /r /o) to access I found that there is a very long list of entries from Windows Boot Manager. When I try to restore the settings within the UEFI it just sits there and locks up. I suspect the reason why (in my case) it appears not to post is that the Windows Boot manager is going through each one looking for boot information or that the boot manager information is corrupt.
I have never been a fan of UEFI and this only cements that

I have an Asus X45C laptop about 10 months old. Yesterday I finished watching a movie with very little battery left, so I closed the lid, put it away and went to bed. This morning the laptop won't boot. Of course I charged the battery all the way, and tried several combinations of turning the laptop on only on AC adapter, only on battery, on both; I also tried removing battery and adapter, holding ON button for several minutes, then trying to power up again with only adapter, only battery, or both, all the time the result is exactly the same, so these are the symptoms:
- Screen is completely black, no bios, no beeps, no anything.
- Power and battery lights turn on (they work ok, if I remove the battery, the light shows that, etc.)
- Hard disk light comes on for about 1 second, then off forever.
- Caps lock and num lock are constantly on.
- Keyboard doesn't do anything at all.
- The DVD unit is working: when I turn the laptop on, it will make noises, and if a disc is inside, it will make even more noises, the usual noises that I get when reading a disc. The button for opening the unit also works. I tried powering up with the DVD unit open, and no noises at all.
- No fans at all are working.
- Also tried using an external monitor, no luck.
I really don't want to RMA it, I know it could be a hardware failure, but it could also be an easy repair. Maybe the CMOS battery or something related to hibernation. Caps lock and num lock always on is what really strikes me.
Oh and one more thing. A couple of times in the past, I had to force a shutdown on the laptop so I would press the ON/OFF button for 4 or 5 seconds.. when it did shutdown, as far as I recall, that was it. When I do that now, I hear a very slight beep after doing a force shutdown. I'm pretty sure this beep was not present when I did force shutdowns before.
Any comments are widely appreciated, thanks!
Update: the beep may have been there before, nevermind. One more sympton: closing the lid doesn't do anything, the same lights are on.
Thanks,

It took 2 replacement boards and a stupid amount of time to find a temporary fix:

I have the same problem (I think). It is not a hardware problem.
I have a multi-bootable Windows 7, Mint 13, and Mint 16 ASUS laptop.
It happened to the Mint 13 system first -- after a Linux kernel update. I worked with the Mint 16 version (that I had as a test partition) and after I updated the software, guess what, same problem.
Windows is unaffected; the hardware is fine. I was using Linux 13 as my main system. It has to be the new kernel.
I am going to see if I can set up an external monitor -- I read somewhere that might work.
I guess I need a version without the new kernel or maybe better, find a way to back off to an earlier kernel version.
Still researching...

I have an Asus k70af and i have the same problem! It may sound crazy but i found a temporary fix:Connect Ac adapter to your laptop, start it and just let it get warmed on bed or something that blocks the airflow.After max 10 minutes it is very possible to work.But is verry important for your laptop to get it warmed.

I suspect CPU fan is the cause of this problem.
My Asus X43 also had the same problem but it is intermittent. Sometimes it boot up, sometimes it's not. Only show black screen with led lights up for few sec. I notice when the fan is running, no problem booting up. When the fan is not running it only turn on led lights for few seconds then lights off. I going to order a new CPU fan from eBay and try if the problem go away. Wish me luck. Will post again if it works.
ps: Forgot to mention, I've tried reinstalled Win 7 from Recovery Disc, swap the RAM module and HDD, reset bios to default and even swap charging adaptor and battery. Problem still come back intermittently.

THANKS! I tried removing the batery and holding ON button several times with no luck, but your solution worked just fine. I removed the battery and disconnected the power, removed the HDD and the screen turned on, so I entered the BIOS, loaded the default settings, plugged back the HDD (with the computer still on), selected "save changes and exit" on the BIOS and it rebooted like always on itself. Again, thank you so much!
Ps: ASUS K54C here.

I had this problem a few months ago. Gave it to the repair center and then they said there was a problem in the board. they replaced a small component on the MB and it was all right again. But i have the same problem again.
What i have concluded is that my laptop over heats time and again which might have damaged the MB. Do let me know if anyone else's laptop overheats too.

Same problem occurred with my k55v after battery ran out. When I plugged adapter and tried to boot, the screen remained black with no sign of asus logo or even backlight. Like it wasnt even plugged to motherboard. As I found out, lot of ASUS notebooks share this problem. After 5 hours i finally managed to successfully boot to windows.
These are the options I tried and you should probably too:
1. Unplug the battery and adapter , hold power butom for about a minute then plug AC adapter back and boot.
2. Dissassemble notebook, remove CMOS battery, put it back after a while then reassemble and boot.
3. Plug adapter, switch the notebook on and let it run for few minutes, then repeat no. 1
4. Let notebook run for few minutes under blanket or wherever you can cover airflow so it will overheat a little.
5. (worked for me) Absolutely dissassemble notebook (even cooler and heatpipes) and reflow chipset and gpu. Only source of appropriate heat i currently had was hair dryer (1400W) and i blew hot air on MB for few minutes and it was enough
After reassembly everything worked

I have an Asus A53S with many of the same problems mentioned above. My problem with this laptop is that everything seems to be in working order except for the screen not coming on. Fans run, hdd boots up, cd drive will attempt to read disks, power button works...
I cannot get any screen reading, nor can I get any beeps or sound out of the speakers.
All this trouble occurred right before I replaced the ac jack on the MB. I figured the MB wouldn't boot properly to protect itself from variable electrical current. Now that I have it replaced, I'm trying everything to get this thing running again. I've tried the CMOS battery, replacing it, taking it out, etc. Removed ram, removed hdd, removed cd drive, removed keyboard, removed battery, removed ac and run off battery. I've even tried the power button trick.
The only significant thing that I can tell is that when you plug in the ac cord, the laptop starts up by itself, letting me know the BIOS is still working (start after failure), but since I cannot even get an external monitor to work with it, I cannot change any BIOS settings.
And when I press the power button, I have to hold it in order to turn it off, which usually means its not hanging at BIOS input, but I could be wrong.
My last resort is to cycle through this list once more, or start messing with the display wires. I see that there is some twisting of the monitor wire inside the casing, but in reality, there are a LOT of tiny wires inside the sheathed coil that I really don't want to open up like a biopsy.
I'll be back with the results of that list, and hopefully something will work. If anyone has any suggestions, please feel free to drop them in. I'm all ears here.
UPDATE: Went through the entire list once, still no luck. Everything is the same, with no screen display or sounds. I'm losing my mind here with this thing. Could it be that the screen is not coming on due to the sensor that detects if the laptop is closed or not? Could the sensor be malfunctioning?

OK this is extremely crazy... I have no idea why, or how?! but... I have the same issue black blank screen on boot.Trying to recover data from a corrupted file system, windows XP home edition.
I placed server into a Linux based live environment, and once I was finished I rebooted the server. It would no longer POST. The screen would blink once, but nothing would happen. I had been working with the computer trying to repair the file system and boot partitions etc. So I figured that it might have overheated or something.
All seemed lost, and it appeared that I was going to have to take it apart and replace the CMOS battery or something was wrong with the motherboard, but then a friend noticed... that he could very faintly see words on the screen when it was tilted a certain way. Come to find out... some how, for some reason... after the reboot... THE BRIGHTNESS DIMMED ITSELF! Fn key + F6 a few times and bam... nothing wrong with it... *shrugs* good luck guys.
