HP Pavilion DV7-1428ca _ CAPS + NUM LOCK Continually Blinks + Will not Start up Black Screen

Would appreciate any suggestions on the issue I am encountering.
I have an HP Pavilion DV7-1428ca that was left powered on, so it went into Safe mode (screen goes blank). Once I came back to my Laptop hitting any key would take out of of the Safe mode however this time it did not. It remained with black screen irregardless of buttons pressed.
Had booted and can hear the fan and hdd go for the 2secs then it stops to a Black Screen with the "CAPS + NUM LOCK" Continually Blinking. Tried to Hard Boot several times but the same thing re-occurs.
It does not seem to be blinking in a series a code, just a steady blink (every sec) for both the CAPS + NUM Lock for as long as I leave it on. HP Site provides a chart from 1-6 series of blink codes which does not seem to apply to me.
Being out of Warranty I am hesitant in bringing it to a local repair shop without trying any alternate trouble shooting first.
Thanks

Hi,
First of all, shutdown the notebook, unplug the AC Adapter unplugged, remove the battery, and then hold down the Power button for a full minute. Plug in the AC Adapter ( leave the battery out ) and see if the notebook will start.

Bricked my touchsmart -tx2 1025dx. Cap/Num lock LEDs blinking once.

Bricked my touchsmart-tx2 1025dx. Cap/Num Lock LEDs blinking once, so I replaced the processor but the LEDs are still giving me a single blink (processor issue). Any advice?

Hey NikosK,
The one-blink code is indicating an issue related to CPU and/or system board (bent pins, etc.). It's possible that the system board needs to be replaced.
Here's a table of all of the LED codes:

Do you know what caused this issue in the first place, before replacing the processor?

Pavilion DV5 1111ea CAPS lock and NUM lock continuously blinking

I recently upgraded my dv5 pavilion 1111ea to windows 8.1
Due to an issue with the OS, it doesn't resume from Hibernation, as described here.
I held down the power button until the laptop swithched off.
Once I tried to put it on again, it couldn't get to the BIOS screen, the CAPS lock AND NUM/SCROLL lock LEDs were blinking continuously, once every 3 seconds.
No disk activity at all.
I checked HP Notebook PCs - Blank Screen LED Error Codes but non corresponded to continuous blinking.
I have a spare CPU which I removed from a discarded dv5, the CPU is exactly the same model with mine (AMD Turion x2 RM-72).
I've troubleshooted by removing both RAMs and testing each individually in different ports, yet no solution.
I'm suspecting the CPU because about a year after purchasing the PC, it began to overheat and hibernate automatically to prevent the CPU from burning. I had to underclock the CPU so, for over three and half year now, I've been running at 50% CPU speed. In total the laptop is 4.5 years old already.
Please I need suggestions as to what to do. I don't have the required tools to replace the cpu myself.
Thanks.

I took my PC to a repairer and he claimed to have replaced the CPU with an AMD Sempron from his collection of scrap laptop CPUs.
After about 3 months, the same problem has recurred.
I opened it up, only to find my former CPU model inside!
Whether the repairer had a spare Turion, or he only performed a trick to make my original CPU to work (and billed me for a replacement), I can't say for sure.
Now I've purchased another CPU from eBay.
Fixed it and...... got dissapointed again.
Still blinking the CPU error code.
From other posts I've come across here, I think HP/AMD combo is to blame for all these.

Caps/num lock buttons blinking

My compaq cq61-411wm can not boot up. It has the sounds of the boot up but every time I have attempted, the wifi and power button lights up, and the caps lock and number lock lights flash once every few seconds.

Thanks.

HP Pavilion tx2500 - Caps Lock and Num Lock lights blink once

I turn on my HP Pavilion tx2500 and I hear the fan spinning but nothing else happens. The lights next to the Caps Lock and above the Num Lock keys blink (a repeating single blink). According to some HP technical support documents I found online, the repeating single blink indicates a CPU problem. My laptop is out of warranty and the $400 to send it to HP to have it fixed is practically the same price I paid for the laptop 2 years ago.
Do the blinking lights mean the CPU is fried? And is there anything I can do to fix the laptop?
Thanks,
-Jeff
This question was solved.

I have the same problem. I called HP they said the same thing. But, I am BIOS engineer myself and has worked with lot of motherboards, So I felt there is no point in sending a 399$ to find what happend and on top of that fixing charges.
I noticed the problem started when I installed Win 7 Ultimate edition to the board and let tbe board Idle for a long time and it went into sleep mode and when I hit the button for resume it would not resume, the blinking started.
I have seen the same thing happend to my friend laptop, luckily for him it recovered and he removed the Sleep Option. SO his laptop is shutdown or running in full power.
I thought this is not coincidence, there is defenitely a bug in HW or SW that is causing it. remove battery. I replaced the memory and removed the cmos battery and left for a long time (short the battery terminals to discharge quickly). Then I rebooted the machine, Luckuly for me it went to windows, I tht of replacing the BIOS firmware, bcos they ahve some latest on by that time I had a visitor and I was talking to him the system went into sleep mode and will never recover. The system started blinking. I dont see this as a CPU problem.
I still evaluating this. I will try to post my findings. I have aclip to read the BIOS chip but everytime i get different read. SO I am planning to remove the BIOS chip and put a socket so that I can play with the BIOS.

TA44551 My 1-year ipod nano locked up and would not start overnight. The on/off button will not work and stopped holding charge. No water damage, no fall, nothing unusual. I restored it (twice) but it will still not hold charge and on/off does not work.

My 1-year ipod nano locked up and would not start overnight. The on/off button will not work and stopped holding charge. No water damage, no fall, nothing unusual. I restored it (twice) but it will still not hold charge and on/off does not work. I tried to restore it again and charged it in three different locations with different cables. etc but nothing. Suggestions?

- After charging for 1/2 hour or so, does iTunes see the iPod? If yes, restore the iPod from backup.
- If no, se if placing the iPod in recovery mode will make it visible so you can restore the iPod. For recovery mode see:
iPhone and iPod touch: Unable to update or restore

The search function in the itunes store does not work. It will accept a request and suggest searches but then it locks up and will not search. Clicking on the magnifying glass or a suggested search does nothing. Re-installing itunes has not helped.

HP Pavilion dv4 will not start up

Hi! I am hoping someone can help me. My friend has an HP Pavilion dv4--2045dx running Windows 7 and it will not start up. Once it is turned on the hp logo appears for a quick second and then a black screen with a blinking cursor in the left, top corner comes up. If I press ctrl alt del and then esc I can get into the menu for F1, F2, F11 etc. I have run and passed all of the system diagnostics tests (Start up, Memory and Hard Drive). I have tried to reset the BIOS to default condition and also tried to connect the laptop to my TV to see if it was the screen that doesn't work, but it wasn't. I tried a hard reset also. When I press F11 for a system recovery, nothing happens. It just goes right back to the black screen with blinking cursor. All of the other F-keys work and I am able to pull up screens for each, except the F11 key.
I am not very computer literate but am trying everything I can think of to get it back to factory settings or system recovery. If anybody out there has any idea what I'm talking about (I'm not sure I even do) please please give me some suggestions!!
I tried to write all of the information I can think of, but if you have any questions about the issue I'll be glad to answer what I can!
Any suggestions/help are GREATLY appreciated!! Thanks in advance for any thoughts you may share!!

Hi,
Try the following to see if the Hard Drive is accessible. The Ubuntu operating system CD you create can run from the CD alone ( ie it doesn't have to install on the Hard Drive ) When you've created the CD, follow the rest of the instructions and see if you can access the HDD - you may want to back up your existing files if you can.

HT3529 Message Notifications show up in lock mode when screen is on, but not showing on black screen (sleep mode).

My texts show up on my lock screen, but not on my black screen (sleep mode). They used to, but not anymore. I have "show messages in lock screen" turned on, but I don't see any options for sleep mode. I have banners turned on. All settings seem to be correct, but in order to see my messages I need to turn on my screen, which is frustrating b/c then I don't see messages when they are first sent. Any advice? Thanks.

Thanks for the response, but I've tried that and it doesn't work. I have friends and family who have their settings exactly the same as mine (including banner) and they get notifications in their sleep screen. It's all very odd.

TS1541 I tried importing email addresses from gmail and now my address book is locked up and will not work. Help please.

I tried importing email addresses from gmail and now my address book is locked up and will not work. Do I need to delete my address book software and reinstall? If so, what is the proper way to do this? New to Macbook software. I have tried several things and nothing has helped. I have backed up photos, movies, etc. My addresses are on my iphone so I can sync them later right if I loose my data?
Thanks for your time and expertise,
T.

You can probably resolve this by removing some Address Book preference files rather than deleting your Address Book application.
First turn off Synchronize in Address Book Preferences if you can.
Next restart Address Book and try to export everything to your Desktop.
I have had a play and found my Address Book preference files. In the following ~/Library is the Library within your Home folder. Any numerals may differ on your Mac. Quit Address Book before doing anything with these.
1 - Display details and things set in Address Book Preferences
~/Library/Preferences/com.apple.AddressBook.plist
2 - Has no data - not sure what this does
~/Library/Preferences/com.apple.AddressBook.abd.plist
3 - Has last sync date - may have more if I used sync
~/Library/Preferences/ByHost/com.apple.AddressBook.sync.000393735c06.plist
4 - My contact details
/Library/Preferences/AddressBookMe.plist
5 - Individual addresses and groups stored as separate files within:
~/Library/Application Support/AddressBook/Metadata
6 - All of these addresses are are also in this single database:
~/Library/Application Support/AddressBook/AddressBook-v22.abcddb
If you wish to remove all addresses drag both 5 & 6 to your Desktop.
If you wish to reset preferences drag 1 your Desktop.
Removing 3 may resolve sync issues but I am unable to test this.
If you wish to reset everything drag all except 4 to your desktop.
Apple has an interesting page at: http://support.apple.com/kb/TS2481
I hope this helps.
