HP Presario CQ61-411WM OS/Software :: Laptop Sometimes Boots But Mostly Get Single Blinking LED On Caps Lock And Num Lock

May 19, 2014

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.

HP G6-1325sa Lockups :: Caps Lock Blinking Continuously - Nothing On Screen

Aug 15, 2014

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.

HP OS/Software :: Pavilion G6-1125sw Not Booting And CAPS Lock Blinking

May 29, 2012

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.

HP Pavilion Dv7-4065dx Lockups :: Will Not Boot With Continual Blinking Caps Lock

Oct 24, 2012

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.

I have a major problem with my hp pavilion dv6-3143sa laptop.

HP Pavilion Dv6-7013cl Lockups :: Black Screen With Caps Lock Led Constantly Blinking On Startup

Oct 12, 2014

The laptop was running hot. I cleaned the dust from the fan area. The battery is bad. I checked the volts on the charger which was 43v - bought a new charger that's 18.5 v. I wiped the ram and started with one and moved to different positions. I now have a black screen with the cap lock key blinking blue non-stop and the f12 key led light is constantly on orange. What I should try next and what does the cap lock led blinking without stopping means - is that a code or have a significance?

Aug 14, 2014

I have several HP 8530p and I getting  the num lock & cap lock leds blinking 5 times which indicates a general system board error.

The system Diagnostics indicates hardware is ok.

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..

Acer :: Caps Lock , Num Lock Osd What Software

Mar 22, 2010

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.

HP G7-1150us Lockups :: Continual Caps / Num Locks Blinking And Wireless On

Jun 18, 2014

HP g7-1150us .....Problem started after replacement of the touch pad/mouse cover. It initially did not power on. I plugged in AC in case the battery was dead and tried again.
Then it started the continual blinking. I tried the hard reset, hitting ESC upon powerup but had no luck. The hard drive is spinning, but not seeking.
I removed the new panel, and put the old one back in and there was no change. I'm confident that I did get all the cables & connectors in correctly.
I thought I may have killed one of the memory sticks, so I tried installing just one. I do not get any of the 6 different blink sequences, it blinks slowly about 1/sec continuously.

Dell Inspiron 17R 7720 SE :: Mid 2012 - Not Powering Up / Only Caps Lock Key Lights Up

Jan 18, 2015

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:


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.

HP Pavilion G6 2241sa :: Caps Lock Light Is Not Working

Apr 3, 2013

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.

Acer Aspire E1 571 :: How To Get Caps Lock Indicator To Show

Jan 8, 2015

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.

Acer Aspire 5742 :: Caps Lock Notification

Dec 7, 2014

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.

Dell :: Inspiron 1501 Will Not Power On. LED Code: Caps And Scroll Lock Illuminated

Oct 6, 2009

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
