Dell Precision M4400 :: Won't Boot / Flashing Caps Lock LED
Nov 20, 2014
My laptop won't boot. I press the power button, the power button lights and I hear the system fan run. Then it shuts off and the caps lock LED flashed about 20 times, then turns off if under battery power. If on AC power then the LED stays steady after flashing. Screen never turns on. Late yesterday and late today the computer started hanging. Usually a restart would fix it for a short while. But now it's dead dead. I suspected overheating so I did a bit of digging and figured out how to remove and clean the fan intake. It's was clogged up pretty good, but that hasn't fixed the problem and the laptop is now cool to touch on the bottom..

I have an inspiron 9400 that has been having some issues lately. As of right now, when I push the power button, the power light comes on but it does not boot or even post. The Num lock stays on and the caps lock and scroll lock lights blink for about 40 seconds then the whole thing shuts off. what those blinking lights mean. I have search dell support but have found nothing.

I have a 1 year old inspiron 1520 laptop which has suddenly stopped working.
When I press the power button, the power light comes on but I don't hear a fan whirring, the battery light also comes on. The screen is totally blank and the caps lock icon continually flashes and after about a minute the computer shuts down.
This happens with the battery attached or connected to the mains.

I have a HP Pavilion dv7-4065dx laptop with Windows 7 64 bit that will not boot up or go to the Bios screen. When the laptop is turned on, you hear the system fan start, power button light comes on, and the caps lock button starts to continually blink once every three to four seconds. The HDD activity light is also on but is solid red with no blinking. No changes have been made to the laptop and it was working perfectly fine just a few hours earlier. I have attempted the hard reset of the computer and reseating of the memory cards, but the laptop still would not boot.

The keyboard on my HP Pavilion g6 is locked. It was working and then my cat ran across the keyboard and must have hit a key that locked it. The mouse pad works. No cap lock or number lock on. I have already tryed:
1) going in control panel and unchecking everything in make keyboard easier to use.
2) Took the battery out for a few minutes.
3) have rebooted computer may times.

Presario CQ61-411WM
Operating System is Windows 7
Most of the time the laptop will not boot up and I get the single blinking LED on Caps Lock and Num Loc. However, if I am persistent and keep trying the start button it will boot up. After it boots up every thing works fine. I can even do a restart and it will stop and boot back up. But if I do a shutdown then I will have to push the start button several times (it will come up with the single blinking LED on Caps Lock and Num Loc) before it will boot up again.

Recently, I turned on the on screen indicators for caps and num lock by accident when trying to get the pop-up window to stop opening every time I hit one of the buttons. Now I don't know how to disable it, and it's a pain while playing games.
Solutions tried:
Going to preference, there is no "On-Screen Display Tab"
Going to run the regedit.

what application gives the osd for the caps lock/num lock that normally shows at the bottom right of the screen, I have volume osd so it must be separate to that.
I wiped and re-installed my os yesterday.
The 5810T does not have an led for caps lock or num lock so the osd indicator is invaluable.

Is there any way to turn off the message that pops up every time you toggle caps lock?

The status light associated with caps lock on the XPS 15 does not show when active. The keyboard backlighting as a whole works.
I have uninstalled then reinstalled the Dell Quickset package but that has made no difference. Is there a setting I am missing?

I own a Dell Inspiron 17R SE 7720.
Recently, out of nowhere the computer is not powering up. I plug the power cable in (without the battery) and the caps lock key's light lights up but nothing else happens.
Once I place the battery into the laptop with the power cable, the third light on the front of the laptop (below the touchpad) lights up in this sequence and keeps repeating itself:
Amber/red
Amber/red
Amber/red
Amber/red
White
Then repeats from beginning.
I have tried the usual, power discharge by making sure all power sources are removed and holding down the power button for 60secs. Tried with known-working RAM and also with an external monitor - no luck.
There are no other POST notifications that I can see, no beeps etc. Just the lights on the front which only happens when the battery is plugged in with the power cord. I cannot find anywhere in the manual what the lights mean.

I tend to hit capslock by aCCIDent a lot.
I have a HP8510, though I don't know if this little thing is part of the HP software or something else I had installed.

Some keyboard keys didn't work properly.
I opened the laptop (Pavilion G6 2241sa) cover and saw that keyboard cable was loose. I reconnected it properly, closed the cover and switched laptop on. Now, all keys are working fine, BUT CAps Lock light is not working well. Key is functioning, but when I press it - the light come on, but as soon as I release the key - the light goes off. Light doesn't stay. Also when the actual function of caps lock is on, when I press any other key the light come on the surface of Caps lock key but it is dim.
I rechecked keyboard cable again - all is fine, but Caps lock light doesn't stay on when pressed. I do practice typing for the last 3 months for few hours each day, so I guess it also affects the life span of my keyboard.

I have an Aspire E5-411... I like many others am experiencing the same issue. A "sound" notification would not work for me. I went to the Windows 8.1 site and saw someone ask the very same question about his Acer a few months ago. The Rep. at the Windows site told him that that feature was locked and he would have to contact his OEM (in this case Acer) how this feature could be unlocked. Is this true? I need to be able to see a caps lock notification.

I have been using this small utility for caps lock on a 5742 using W7 Pro and it works well. The 5742 doesn't have a caps lock light or indicator built into from Acer, so one have to come up with something.
This program will place a red "x" or green "check" in the taskbar letting you know if you're in caps lock and will also produce a small "beep" after a few letters typed in if in caps lock.

My fiance has had an Inspiron 1501 for some time. Today after she put the computer to sleep, the PC would not come out of sleep mode (typical windows problem); however,
button the fan kicks on and then the screen stays black and the CAPS lock and SCROLL lock lights come on and stay illuminated. I could not find the POST code for these two lights remaining on. I've tried re-seating the processor, as well as cleaning out the heat sinks.
I'm afraid that the PC may have overheated and fried the board/processor/some component, but I wanted some advice before I began searching for a new laptop

my CS.
sony tech did a repair on my laptop and when he was done, a piece of the trim wasn't flush near the LCD hinge. To fix this, I put a drop of krazy glue under the hinge (it snaps off) on the panel above the keyboard and was able to fix the problem cleanly.
The problem is, I noticed my caps lock light no longer turns on. I have no clue when this could have happened, since it was under a couple repairs before. But, my worry is my warranty. Do you think they'll complain about replacing it if they see I had to glue a piece together? On the other hand, the light module screws into this panel so, technically they don't need to replace this panel, just the light module.

I have an HP g6-1325sa had an issue that had to replace the fan. However since then nothing will appear on the screen F12 has an orange light on and the caps lock continuously flashes every 2-3 seconds. This is not a blink code it does this continuously.So far i have tried blocking the vents and leaving the laptop running for over an hour as I heard it can be caused by dry solder joints.
I have also tried replacing the motherboard and have twice managed to get a cursor flashing on the screen however niether of these times could a normal boot happen as the HDD was disconnected on both of these occassions, the first time this happened i had just disconnected power and battery and held down power for 30 seconds, i'm guessing that was a cmos reset.
The only cause i can think of is that the processor was cooked when the fan was replaced but having already paid for another motherboard i'd like someone to confirm what it means when the caps lock blinks endlessly and if there is another way to repair it.

On they old keyboard, there was a dedicated green indicatory light on the key itself, which is missing on the keyboard. Now, I realize that the new keyboard affects all thinkpads alike, but the reason I'm posting this here is because my Thinkpad Edge (E530) has a dedicated numpad, thereby making me use the numlock much more often
I am aware of the often-suggested windows 7 software-sided fix: screen resolution > advanced settings > on screen display
However, the issue with this is that is that it groups the caps lock and numlock together. What if I want the numlock to be default on and NOT shown on-screen, but still wanted to be reminded on-screen if I [accidentally] have the caps lock on?
Is there a solution to this or is this another problem that Lenovo overlooked when upgrading the keyboard?

I am using an HP Pavilion g6-1125sw laptop. The laptop is about 5 months old and 2 days ago something odd happened. Let me start from the beginning; I was changing the graphics properties of a game and when I pressed "Proceed with changes", the screen went blank but the computer was still working. So I switched it off (took the battery out) and booted again, and it went as far as to my wallpaper and I was able to view my wallpaper and all for a about minute then screen went blank again. I tried using HP advanced diagnostic tools that come up just when you boot up, but even with that the screen went blank.
The next day the laptop didn't even boot up, the fans were whirring but not the BIOS screen came up. The CAPS lock button is blinking in intervals of two, the wireless button is orange and thats it. Its been like this ever since.

I am having a problem whereby it takes ages for my caps lock to go from capital letters back to normal & vice versa.
The little bag with the A coms on then you have to wait a few seconds for it to click off then you can start to type again.
I had this problem when I first got the laptop & it rectify itself but now the dreaded thing is back again, as I remember it was a problem as I remember someone mentioning something about the same problem before.
Either email or office its still the same. I am forever using the shift button to get around this problem...
