Pavilion DV4-1070ee got stuck on a blank screen and numlock and caps lock LED are blinking..

My pavilion dv4-1070 got stuck on a blank screen and numlock and caps lock LED are blinking... it happens when i update the BIOS.. please help... thanks

Hello,
I see that you're having an issue with the notebook giving you a black screen. I also noticed you said only the NumLock and Caps lock is blinking.
Now, the BIOS update could have because this but we won't know until you let me know how many times the LED blinks.
Here is a chart which will tell us what's causing the issue.
Please let me know the outcome.

HP Pavilion DV3 ( Scroll & Caps Lock LED's blinking four times + Blank Screen )

Hi,
I have an HP Pavilion DV3-2157cl
When I press the power button, the screen remains blank. Also, the scroll & the Caps Lock buttons keep blinking four times.
Sometimes, the laptop works like nothing's wrong but Most of the time, it remains blank with the blinking lights!
Can anyone help me?

i had a problem with my dv3 (blank screen keeps flashing) and used this method to reflow the graphics card/chip (see link below). only try this method if you are at your wits end... and you are skilled with taking apart/putting together electronics. it will take you a minimum of 1 hour (but most likely, about 2). you will need a heat gun (about $10 - $20).

to prevent it from continually over heating, you can try the penny mod (google it). that's what i did. you basically take a penny and sand off both sides until it is the right thickness and solder it onto the heatsink. you'll need to remove the sticky blue foam that HP used instead.
i also noticed that a laptop cooler placed under your laptop works well for keeping it cool. it can be fixed again and again using the method above but it is time consuming. to prevent getting a cold connection which leads to this problem, don't move the laptop. yes, it sucks that you can't move it but that's the only option you have.

Blank screen orange wifi and mute lights

Hello,
I have a Pavilion Dv4 laptop that does not boot. It seems to be in hibernation with the wifi and wan lights in orange.
I can hear the fan spinning. It spins and then stops and spins again. The DVD light comes on and the numllock and caps locks blink in sequence of 1 continuously.
Please help me! I need my laptop to use.

Hi jendy,
Welcome to the HP Support Forums!
I understand that you are getting no display, but the Caps lock and Num lock LEDs are blinking. I am happy to help you with this. The below document shows the meaning of the error codes.
Blank Screen LED Error Codes
If the lights are flashing just once and then repeating that sequence, it indicates that the CPU is not functional. If that code is correct then I recommend calling the support line. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Start at # 3

3 If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
4 Try on another computer
5 If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

You can get there from here (booting normally); it just may take you a few steps to do it.
If the disk is almost full and the system won't boot then sometimes it will boot in Safe Mode.
http://support.apple.com/kb/HT1564?viewlocale=en_US
Empty the trash after it boots.
Then for hints on how to free disk/SSD storage see https://discussions.apple.com/thread/5872318?tstart=0
If the Safe Mode boot does not do the trick then you can install OS X on an external hard disk, boot from that, and then delete files. You can also reach the disk via Target Mode. A third option is to take it to an Apple store where they can do a network boot and help you remove some files.

Two Macbook pros circa 2009 in our temporary household in Turkey suddenly failed to boot and got stuck on the grey screen. They were able to boot at the Apple store, but not when we brought them back to our apartment. Could this be a coincidence? A

THank you Ogelthorpe. When my wife's computer I went on line to the site that you sent and tried everything But nothing worked. When my son came to visit and his MacBook Pro did exactly the same thing we became suspicious - too much of a coincidence. We took both computers somewhere else, out of our apartment, and they both booted. We ran disk utility on both, but the report in both cases was that there are no issues with the hard drive. Back in our apartment neither will boot up. My MacBook Pro is a later model with a solid state drive and it seems to work fine here.. I tried an external drive and it works fine. We think that this has something to do with some kind of magnetic interference in our apartment to which the 2009 drives are susceptible. It is indeed a mystery!

I turned on filevault but after restarting i got stuck at the login screen.

I turned on filevault but after restarting i got stuck at the login screen. my trackpad is working but not clicking. i tried random keys and finally got to enter my password via keyboard. now i am afraid of shutting my mac , what to do?

There is a known problem and I am having exact same issue. Power cycling and internet cache does not fix the issue. When a connection to a server fails it has nothing to do with caching issues. It is a network issue on AT&Ts end in a localized region. It works in multiple towers in various locations but does not work where I am. I have reported this to AT&T.

Priscilla,
if your Mac is still in warranty, then you should contact the Argentinian technical support service. If it is out of warranty, then we can try to lend a hand. (We’re just fellow Apple product users here.)
