Caps lock and Scroll lock blink continuously without stopping

HP Pavilion Dv5 1004nr entertainment notebook. Caps lock & scroll lock blink continuously. Power light is on. Power light does not flash. Fan and drive start upon powering up. Held down 4 arrow keys during power up, but does not solve problem. Removed all external devices and removed battery. Same problem. Please help.

Urgh, appears to be bad RAM... Running memtest and switching sticks in and out only shows errors with one particular RAM stick installed. I'll leave this stick out and try installing Arch again once the current memtest pass is finished.
I'd have expected better from Patriot!

CAPS Lock and Scroll Lock blinking / Display is Black

Hi,
I am using DV5 with processor AMD Turion X2 RM70. CAPS Lock and Scroll Lock blinking once every 4 secs.
Is it Blink Code Error? Is my CPU dead? Should i take to service centre(No Warranty)? If CPU failure, how much the CPU costs?
Please help me.
Thanks,
Rahul

Could i use a older USB keyboard with caps, num, and scroll lock LEDs to...

controll a motor? use the power from the LEDs (snipping the LEDs off so they dont draw power) and hook them up to a motor? im thinking about making a DIY cd/dvd duplicator out of a USB scanner. Mabey i should use the existing controller board in the scanner to control motors?....but that would require proramming. Help would be much appreciated. Thanks

Not really my area of expertise but....
I'd say you coukd use the LED outputs to trigger relays as the voltage and current would be too low for any useful motor. A typical LED is supplied ~ 2.1 VDC @ ~20 mA. ( could be as low as 2 mA ).

[SOLVED] Kernel Panic - caps lock and scroll lock flashing

So I just spent a whole bunch of $$$ on a new desktop, and a couple of hours putting it all together, now I can't get anything except kernel panics when booting the Arch install CD
Hardware:
Core 2 Quad Q8400
Gigabyte EP43-UD3L
8gb RAM
2 x Seagate SATA 160gb
2 x Seagate SATA 1tb
So far I've tried:
- Arch ISO 2008.06 and 2009.02
- Fail Safe Defaults in the BIOS
- 'noapic' boot option
- HPET in 32 and 64 bit mode
The strange thing is that the panic comes at various stages - sometimes before the init scripts start, sometimes after, and also during boot it complains about errors with fd0 - except there is no floppy drive.
Any ideas folks?

Pavilion dv4-1275mx notebook - once-flashing leds @ caps lock and scroll keys @ start-up

My HP Pavilion dv4-1275mx notebook runs Windows Vista Home Premium service pack 1 for 64x-based systems.
Recently, when I turn it on, the led lights @ the caps lock and scroll keys repeatedly flash once.
I'm not sure what, if anything, happened prior to this starting. It's possible that there was a power surge when it was shut off, or it may be related to doing a McAfee virus scan or installing the latest version of a software, e.g., Adobe Reader.
I was able to use my System Recovery disks to reinstall the Vista software, thinking this might "kickstart" my computer into working, e.g., as part of the restart process. After the reinstallation, I was able to use my computer, although the led lights continued to flash. However, once I shut down my computer, I have been unable to restart it. The leds continue to flash upon start-up, and I have not been successful in again reinstalling the Vista software. (I thought if could get my computer to work again that way, it might stay accessible if I used hiberate mode instead of shutting it down.)
The computer's about 4-1/2 years old. The screen has a short of some kind (only turning on when the screen is low to the keyboard, so I use an external monitor.

Try the steps in the following weblink:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c00372748
If the issue persists, please read the following document, understand the LED blink code, identify the root cause and try troubleshooting appropriately:

Caps-lock and scoll-lock LEDs blinking

Ok so a friend gave me 2 dv7-1245dx laptops. When I turn them on both screens do nothing,and the caps and scroll lock LEDs blink every 3 sec apart. On one of them the dvd drive also acts like it is trying to read a disc. External monitor didn't owkr,nor did changing ram to a set that know works,and swapped CMOS batterys between the 2 didn't help either. Also did a hard reset which also didn't help. Any suggestions?

It sounds like they may be experiencing a processor failure if it blinks only once with a 3-4 second pause between each blink.
Review this document as it has the decoding table for the blink codes.
One blink indicates that the processor has failed. While it is is unlikely to happen on two notebooks simultaneously, it's not impossible.
The steps listed in the document is to reseat the processor or to have the unit serviced.
Normally, HP has a guide for most of the notebooks on how to reseat/replace the processor. However, this particular system does not list the maintenance and service guide here.

Blinking Caps Lock and Num Lock Keys Lit after spilling water Macbook Pro.

What does it mean when the caps lock and Num lock key blink, after spilling liquid on a Macbook Pro? Does this mean that liquid is still present? Also, the white light by the latch was blinking. What does this all mean?

Possible liquid damage.
Immediately disconnect all peripherals, power cord & remove the battery. Turn the computer over with the lid partly open and the hinge facing upward to let the liquid drain. Do not flop it over and lay it flat - you want to separate it from the moisture. Place paper or cloth towels under the machine to sop up the mess.
After the computer disgorges whatever you spilled on it, don't turn it on for 72 hours or longer. You want to computer to dry out completely before turning it on again.
Some users here swear by hairdryers. Blow drying the innards may bake whatever was in the liquid onto delicate computer components. Better to let the computer air dry.
Use plain tepid water to clean out the computer. If you spilled iced beverage more than likely this ice fried the hot motherboard.
Sugary, acidic or milky drinks will almost always cause problems later on as the residue starts slowly corroding the computer innards.
Swab down any sticky parts with distilled water or denatured alcohol.
If none of the above works, you will need to take the computer to a repair shop. Apple Care does not cover liquid or food damage. Believe me, they can tell. So the old "my computer stopped working" line is not going to work.

DV4 flashing caps lock and num lock lights

My laptop, an HP Pavilion DV4-2040US, has stopped booting up recently. The day before this problem come about I was using the laptop perfectly fine. I then went one day without using. When I turn on the laptop it booted up but nothing showed up on the screen. Then the CAPS LOCK and NUM LOCK lights started to blink on and off.
I did some researching about the blinking lights and what they mean but I don't think mine is listed on there. It says the pattern will repeat a couple of times then shut off, but mine doesn't. The pattern is the CAPS LOCK and NUM LOCK both blink once every 3 seconds (about) and keeps blinking every 3 seconds forever. The only time they stop blinking is when I shut I down by holding the power button on the laptop.
I've tried disconnecting everything and holding for 15 seconds and even tried holding it for 30 seconds and that still didn't fix the problem. I called HP support and the guy who I talked to told me it sounded like a motherboard issue, but he wasn't sure exactly and told me to ask here for help.
If it matters, I can hear the fan turn on for about 2 seconds then stop. Also all the touch sensitive buttons light up too$

Please, someone, anyone help me. I am having this exact same problem as we speak It happened after i put the laptop to sleep overnight. The LEDs for capslock and numlock blink consistently but slowly-approximatelt 2-3 seconds. When started up, i hear the fan come on for maybe a second or two and then comes off.I've tried all the mentioned solutions - i removed the battery for a while and put it back in-i tried the four arrows-i tried started up with AC adapted but without battery - and still no fix. What i am worried about is the documents and files on the laptop. Are they recoverable? Please help me on this someone. Please. Thank You.

Updating caps lock and num lock status

I need to keep track of the status of the caps lock and num lock keys in a status bar of my frame.
I get the current status with a code like this
Toolkit toolkit = Toolkit.getDefaultToolkit();
numLockState = toolkit.getLockingKeyState(KeyEvent.VK_NUM_LOCK);
capsLockState = toolkit.getLockingKeyState(KeyEvent.VK_CAPS_LOCK);
fireChangeEvent();
where fireChangeEvent() updates a label in the status bar. The code is invoked when any of the caps lock and num lock keys are pressed (while the window has the focus) and when the window is activated. This code works while the window has the focus (i.e. the status of the keys if correctly tracked). It does not work correctly when the window is activated.
Specifically the following scenario fails:
- The window has focus and the state of the keys if correctly reported by the code above (say caps lock up, num lock
up);
- The window loses focus, i.e., another (non java) window gains the focus;
- The user presses any of the two keys (say the caps lock key);
- The window regains focus.
When the latter event happens the code above is invoked (as a consequence of the window being activated) but it continues to report the status of the keys at the time the focus was lost by the window (caps lock up, num lock up).
It seems that the toolkit does not automatically updates its internal status if a key is pressed when the java window does not have the focus. If I press the caps lock key (so that it returns to the up state) after the window has regained focus the status is updated and the new state is correctly reported. I need to manually realign the status by pressing the keys to have them correctly reported by the toolkit.
Some ideas on how to have correct key status even after the window looses the focus?
Thanks.

- The window has focus and the state of the keys if correctly reported by the code above (say caps lock up, num lock
up);

the only is though it is not sensing the keyStrokes but if window looses focus because of another window gains focus it changes the values when it get focus next by ne means.
Provide a short executable code might be the problem lies there.

So the physical indicators got nothing to do with it.

X220 - swapping numlock and scroll lock

Hello,
does anybody know, how to swap these both keys? I've searched the registry, but I haven't found anything... Ideal state would be just change the values - in a result numlock would be turned on by pressing "scrlk" key, and scroll lock would be turned on by "fn+scrlk". Num lock would help me a lot, since I don't use Excel very often.
I would be very glad for all suggestions!
Thank You and wish a nice day!
Skrble

Try KeyTweak.
I can't confirm Fn+keys combinations remapping capability.
