I saw your post regarding the LEDs not blinking on your Pavilion. Is there something else wrong with your Pavilion or just that those lights do not come on?

Hello SuperMario1,
Thanks for your response.
The last thing i did, remove CMOS battery and after a few minutes i plugged it.
Then connect AC power adapter and press power button.
Laptop starts but gives a error message
"The CMOS checksum is invalid, The BIOS will be reset to the default configuration and will be rebooted."
Finally laptop start normally. It works fine ...
But same problem when i restart
"blank screen caps lock blink 2 times every 3/4 sec"
So finally
1. remove CMOS battery and after a few minutes i plugged it again
2. connect AC power adapter and press power button
3. laptops starts normally (with a error msg same as previous)
4. Upgrade bios to F.29(previously i had F.24)
5. Everythings works fine (restart/shutdown have no effect)

HP Pavilion DV6 blank screen caps lock flashing continuously

My laptop was working fine last night, this morning the screen stays blank, caps lock flashes once every 3 seconds or so continuously, the wireless light is solid amber, no other lights are on. I've tried a hard reset to no avail.
When I power it on it sounds like the fan spins up and it tries to boot, then 2 seconds later it is quiet and nothing happens, if I close the lid without powering off the outside light on the top of the case stays on so it is not shutting down or in sleep mode when the case is closed.
I've looked at a bunch of troubleshooting and none of the info seems to match this, any help would be appreciated.
Thanks

a single CAPS flash is a CPU failure, you can try following the below steps but it will most likely need to go in for repair
power drain;-
-remove battery and power cable
-hold power button for 20 seconds
BIOS recovery;-
-hold windows+B
-turn computer on keeping those keys held down
if the light is still flashing at this point you'll need to contact HP, if it is in warranty then the repair should be free, if not there will be a cost

Hp g62 Black screen caps lock on and wifi button on

Hello,
My friend is having a problem with his laptop hp g62 which is 1 1/2 years old. This happened out of no where and have no idea why. Here is what happens: We power it up, fans turns on, caps lock stays on and Screen stays blank. Again we have no clue why this is happening. Any help will be apreciated.

Hi,
It's always worth trying a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and see if the notebook will start.

If the above fails to help, as your notebook is still under warranty, contact HP and arrange to have it repaired - you can check your warranty status Here.

****PLEASE HELP ME SOMEONE**** PLEASE - Re: ON SCREEN CAPS LOCK INDICATOR

can someone please help me before i pull all of my hair out.
i have windows vista - 64 bit - the HP IQ500 touchsmart with a wireless keyboard.
in the systray the num caps and scroll lock appears as little blue boxes (when on).
everynow and again they simply disapper.
i researced how to activate them again but cant remember how to do it.
there is a way without having to mess with the registry and without downloading any program
i just cant remember how. i know wherever it is...you ultimately get 3 boxes that you can check in order to turn the options back on.
i am not talking about toggling, or sound, or mscofig and then boot.
does anyone know the steps to turn the caps scroll and num lock indicator in teh sys tray back on
oh, and right clicking on the toolbar and going to the notificiation area is not what i am referring to either.
I checked in the control panel programs and the hp on screen caps lock indicator etc program is there.
I reinstalled it nonetheless and confirmed it is installed properly
When I right click on the notification area I do to properties/notification area/customize
There are two lists there
1. Current Items and
2. Past Items
For some reason I see caps lock - scroll lock and num lock under the past items
There you are also able to change the status of the items to either Hide wne active, hide or show
All three (caps/num/scroll) are SHOW
I click apply OK then apply
I restart the computer and nothing. The on screen caps lock indicator is still not in the notification area/systray area
I repeat teh steps to ensure that the three have the SHOW option chosen and they are.
So....
Program is installed
Items are check for SHOW
Restart was done
Ohhh and also...I went to MSCONFIG and made sure that the HP Keyboard Program was selected/check mark as one of the start up programs.
There in a run command to activiate the 3rd party program (hp onscreen indicator program)
When you enter the run command that I cant remember...you then get this option where there are three check boxes...one next to num lock - one next to caps lock and one for scroll lock.
Once you check/select the boxes/options you want...presto they appear in the sys tray/notification area.
I just cant remember the run command it to save my life.
Please....put my mind to ease...cause I am losing it!
I just cant seem to "walk away"...must be my OCD :-(
Thanks

Caps Lock is "OPPOSITE" green light ON is lowercase - light OFF is CAPS??

Hello...
WEIRD circumstance that I noticed with my PowerBook G4. Everything else seems to be functioning fine but my caps lock key is screwy.
When the light is ON the type is lower case but when the light is OFF the type is UPPERCASE/CAPS LOCK!! So, the previous function of the Caps Lock key and light indicator reversed!!
Anyone have this problem or know how to fix?? It's 90% annoying but also a BIG problem when typing in my numerous passwords that are cAsE SeNSitIVe because with the •••••••• seen when you enter a passwork, I can't keep track if I am lowercase or CAPS.
Thanks!!
Scott

**ADDITIONAL PROBLEM**
Here's another issue that just came up...
In the same way that I explained the Caps Lock key not working, now the NUM LOCK (F6) is doing the SAME THING. For the Numbers Lock to be OFF the light (F6 key) has to be ON (and I can then use my keyboard) but if the Numbers Lock light in OFF then the numbers lock key is ENGAGED (e.g., my U, I and O keys are 4, 5, 6)
So, my Caps Lock and Num Lock keys are "backwards"....light ON is NOT engaged (works normal) and light OFF is ENGAGED!
Any soloutions??
THANKS!!
Scott

How can you keep the caps lock on and not unlock after each letter?

How can you keep the caps lock on and not unlock after each letter?

I'm not aware of an online keyboard that is available and can do this. Most likely it would need to be a function of the app itself (which can and sometimes do add functionlaity to the keyboard).
Wireless keyboard might handle that, if that's an option for you.
I work in IT myself, and IMHO the iPad isn't the ideal device for coding or scripting work.

HT1338 When I connect my Macbook Pro to my Dell DLP projector, either via cable or wirelessly, I just see a dark screen with the mouse and mouse trails only, can any one help?

jpmarkques post is a good start point, after folling his directions, you can try detect displays. Also try different rsolution and refresh rates.
Most of the projectors I have used support a 1024X768 res.
Youcan also try a pram reset if it still does not detect.
Leave theproctor connected and powered up, power down the MBP.
Power back up the MBP and hold the following keys before you hear the start up chime:
Option, command, P,R (no commas) continue to hold these keys till you hear the start up chime 2 times.

You repeat yourself frequently frequently. Perhaps your iPhone is not charged.
