HP laptop G62 Blue led light blinking on the caps lock button

When booting up get a black screen. The Caps Lock blue led light is blinking once.
 1: Tried a hard reset Removed battery, held down the power button for 15 seconds and tried again no luck.
 2: Air cleaned the power vents around the fan same again no boot.
 3:  Founf the LED code chart for the blinks mine appears to blink once and a pause then blink again
      the blink code chart say  CPU Not Functional.
 Does this mean the systemboard / motherboard is bad / fried
Thanks

Dear Customer,
Welcome and Thank you for posting your query on HP Support Forum
It looks like your Notebook has a blinking/flashing CAPSLOCK light and a blank screen all the time
Whenever the Capslock LED Blinks once that means CPU not functional and we need to replace the Processor
However, I would request with you to perform the below shown step before contacting HP
Step 01. Turn OFF the Notebook
Step 02. Un-plug the Power/AC Adapter and also remove the battery too
Step 03. Press and Hold the Power Button on the Notebook for a full minute
Step 04. Test your Notebook with Battery and Power Adapter alone
Note: If you are still facing the same issue try to remove and reseat the Memory Modules of your Notebook
Hope this helps, for any further queries reply to the post and feel free to join us again

  • Is there a way to eneble the caps light while the caps lock is off

    I would like to have my computer so that the green LED is on when the caps lock is off. Is there any way?

    It's very unlikely that there is any way to do that. Why not just learn to accept that what the light means is what it means?

  • Pavilion dv7-4051nv will not post, no display abd blinking caps lock button

    I am working on this laptop that was working fine last week.  Now it will not display, no post beep and the caps lock button blinks constantly every 3 seconds.  What can I check?
    Thanks

    Hi
    Try a hard reset,
    Disconnect all external devices first.
    Remove power cord and battery
    Press power button for 30 seconds
    Reinstall only power cord for first startup.
    Power on
    If no response
    Try to Enter BIOS setup by tapping/holding the F10 key immediately after powering on the laptop.
    Use Diagnostics to test your hdd - extensive.
    If you cannot get the system to power on,
    Manual: http://h10032.www1.hp.com/ctg/Manual/c02642701.pdf
    Try reseating the hard drive by disconnecting & reconnecting SATA cable gently & firmly
    Try reseating memory module
    Power on & check

  • Hp pavillion dv7-3065 laptop will not turn on - led light blinks, ac's light on?

    HP Pavillion dv7-3065 with Windows 7.
    I fell asleep two days ago, and when I woke up yesterday, my laptop was off. (The battery very well may have died while I was sleeping, or just shut off on its own. I don't know which.) I tried turning it on, but nothing happened... except for the lightning bolt (LED light) blinking three times. No noises inside, blank screen, nothing aside those three blinks.
    For the record, I've already tried removing the battery. I've also tried removing the battery, removing the AC cord, and holding in the power button for 30+ seconds. It didn't work.
    I've tried removing the battery and running off AC. This still doesn't work. However, the laptop recognizes that it's plugged in; the little light by it is consistantly on. I've also tested my laptop with another AC adapter just to be safe. Nothing.
    My laptop has been tested without harddrive/etc, but I'm still at a blank. I don't know what else to do. My boyfriend, who's in school to be an IT, took it into his teacher, who messed around with it, and came up with a few conclusions.
    He believes that because the lights are flashing, he's confidant that my motherboard is fine. He said to replace the battery, and if that doesn't work, solder the ...I forgot what exactly, but basically it's the charging connection. I forget what exactly. My apologies there.
    However... I feel like replacing the battery would be a waste of money... Because regardless of battery, the laptop should still turn on with the AC cord. My boyfriend intends to bring this up and ask if he can just skip to the other thing anyway, but he doesn't have that class again for a week, and I'm at a loss of what else to do. Aside from that, his teacher says there's a limited number of other things that could be wrong...
    I was hoping to get some more input... 

    This won't help you out, but I am experiencing the same problem... I am gonna look on this post to see if you get an answer!
    I have the same problem! Except I did manage to get mine to turn on. After doing the hold the power down thing. Nothing happened. I did leave the lap top on cause I was irritated and walked away, about an hour later it came on. It let me turn it on and off a few times. Then stopped. Then leaving it sit on stopped working too

  • TX2517ca, wont Boot - Blinking blue LED lights - Num Lock & Caps Lock

    notebook just decided NOT to boot one day..I can hear the fan and very minimal HDD activity. I've tried the Hard reset as directed by HP and removed the battery etc...  the lights blink exactly the same time, stay on for 1 sec, and the off for 3 seconds and then blink simultaneously again, and doesn't stop till I pull the power, there is no clicking, grinding, beeping nothing, nothing on the screen at all. The rest of the lighted buttons are solid blue.
    FYI, I am a computer technician of 15 years...home based at this time. so I have pulled the memory, cleaned them, 2 (1GB & 2Gb), compress air dried them and blue out the slots and reseated even by doing only 1 at a time, no change, same end result, blinking LED's. So I just pulled the Hard drive, connected it to another machine as an external HDD, it works fine, I can see the C drive and the Recovery drive without any problems. so at this point I have just pulled the battery from the board and will leave for a while to see if we can drain the BIOS/CMOS (wondering if software is stuck in hibernate or sleep and when powering on is only returning to similiar state, but wouldn't account for no screen display...) everything so far is pointing to CPU I would think. Next after replacing existing Hard drive and try booting if that doesn't work, I have a working blank Hard drive I can insert to try for the hell of it...stay tuned...
    Oh, also system is immaculate, no collected hair or dust in fan ports etc..
    This question was solved.

  • Laptop Won't Boot. Caps Lock Button Light Blinking

    I just bought a HP Pavilion DM4-2015dx laptop a few days ago.  Turning it on this morning, it won't boot and the Caps Lock light  is blinking.  I have searched the HP site and Google for a solution to the problem and have found nothing to tell me what the blinking light means or why it won't boot up.  Does anyone have an idea of what the blinking light on the Caps Button means?

    My laptop HP pavilion Dv6 - 7132TX had a problem of blank screen and caps lock key blinking. I bought the laptop on 28th Apr 2012 and just before completing a year, I was facing a problem of computer inadvertently not booting. It used to show black screen with wifi LED red, power button LED glowing, and caps lock key LED blinking. http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&docname=c01443366 On going to the above link, I tried to notice the number of blinks of caps lock key  LED.Found that the blink count was an endless loop of 2 LED blinks. On checking in the above link, found that 2 blinks meant the problem was BIOS corruption failure. LEDs blink 2 times BIOSBIOS corruption failure(as found in the table in the above link) So I went on and found another link to find the BIOS upgrade on the same page , where it read, Step 3: Find and download BIOS updates Then followed to the link: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?swlinkmsg=100&cc=us&dlc=en&docname=c00042629&lc=en&product=4057208 to download the driver. Downloaded the BIOS latest driver and installed it. It gave the same problem while restarting the laptop which was required to complete the bios installation. Link for the BIOS installation: http://ftp.hp.com/pub/softpaq/sp54501-55000/sp54629.exe However after several force shutdowns and reboots (since in my laptop the blank screen during bootup was inadvertent and random..) the installation could proceed and complete. After that voila.. Problem gone Hopefully it stays that way. Now next task on my mind is to fix the sleeping problem of my PC and the noise problem of the speakers. 1.Laptop does not sleep and goes into freeze mode with LEDS glowing and screen black.2.While the laptop speakers are on, they constantly make some background noise as if the speakers have a loose connection. However I got a clue that the problem is not with the connections but with the frequencies mismatch. Inherent problem of laptop architecture I suppose. However still wish to hear sounds clearly on my laptop. Had a good experience with HP with my earlier laptop from HP. However now things are changing I guess. Feel good that I could at least troubleshoot and save money. [Even gas is Rs. 84 per litre.] and more importantly time since I was working when I saw this problem and did not want to keep laptop powered on All the time just to avoid restart .      

  • Blue LED Lighting showing up as purple

    Using a Canon 60D and having some issues taking photosgraphs that use intense blue LED lighting and showing up as purple instead of blue
    Below is an example of  a set I am trying to shoot but the blue is turning out purple.
    I have tried all the different color balance settings which will affect white causing it to be a cool white and all the way to warm white but the blue uplighting remains purple.
    What I also found interesting is that I took some shots with my iphone and the blue comes out correctly.
    Anybody know how I can fix the problem or is this a limit with the sensor on the 60D? Would a higher end Canon camera fix this?

    The camera display is a jpg that has the white balance and camera style settings applied, even if you're shooting in raw.
    Also, when you go back, if you have another lens try a photo with that, even if it's a different focal length.  I'm guessing it's probably a combo of white balance, over-exposure color shift, purple fringing CA, and maybe some camera settings tossed in for good measure.  I'm sure I'll be around there this weekend, I'll drag a camera around for grins.

  • Phone turns off and led light blinks wont turn back on

    I have the 8100 and have had it for about 2 weeks I bought it off line since my old phone broke. This morning I took it off my charger and went to a meeting after the meeting I looked at my phone and the led light was blinking I hit a button and nothing happened. I then tried to turn the phone back on but nothing happened. I removed the battery waited 5 minutes then put it back in and it started to work again. But again the same thing happened. I tried this multiple times but nothing change it still went back after a few minutes. I took the battery out sim card and memory card out for an hour then put them back in and the same thing happened. Has anyone had this happen before and is there anything I can do for it. Again after I turn my phone on it "shuts off" the led light blinks like I have a message but I ca not do anything the only way to get it out of this is to remove the battery and put it back in but it reverts back to this in a few minutes. Any help would be greatly appreciated thanks

    Greetings, and welcome to the BlackBerry.com Support Forums.
    Leave the device to charge 2-3 hours, and then, still connected to the USB cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage).
    If it doesn't boot--try using a wall outlet charger if you are not. If you are connected via USB to the PC, make certain that you have Desktop Manager (or the USB device drivers) installed, which you can download below.
    Make certain your USB cable is connected to one of the PC's main rear USB ports. Not a USB hub, nor a monitor USB port, nor a USB port on the front of the PC.
    Download Desktop Manager from here:

    Hello,
    I've been experiencing in the last couple of days a problem with my hp laptop: while logging in after turning on the pc, the caps lock while light starts blinking for almost a minute,then stops.

    How can i fix this problem?
    P.S. i own a hp g6

    My apple TV is not working. The light blinks but the TV only shows the apple picture and nothing happens. Any idea why?

    James,
    Thank you for the information. I did what you said but it is still not working. My apple box works with my wifi so I think the wife was disconnected and I can't figure out where to go to set up the wifi pass word for the apple box. Any hits would be appreciated if not my next step is to ship back the box to apple.
    Thanks,
