Pavilion Dv5-1009el - Black screen and blink caps lock and block scorr

Hi,
I just replaced the motherboard of my pavilion that reported an error as object. The purchased motherboard is new and hp original.
After having changed, I turn on the pc and work fine, i see the hp logo and enter to bios, after I turned off the pc without starting windows.
I inserted the battery and powered on the pc and returns to the old error, the LED of caps lock and block Lock blinks...
So I tried to update the bios from USB using winkey + B. The computer emits two beeps but does not read from any USB port and the LEDs go out for a while and then blink again.
What can I do?
Greetings,
Enzo.

Hi @shmurray,
Welcome to the HP Support Forums!
I understand you are getting a blink pattern on the Caps lock LED, when you turn on the notebook. I am happy to help you with this.
I am including the page on the error codes for your reference: Blank Screen LED Error Codes
From that document the pattern you are getting indicates a memory problem. You said that you have tested the memory. What exactly did you try?
The document suggests reseating the RAM or trying a new set of RAM and then restarting the notebook. If you are still getting a memory problem after trying both of those things, ie a 3 blink code again, then it would likely suggest that there is a problem with the motherboard itself, either with the memory slot or one of the controllers related to memory.
In that case I would suggest contacting the technical phone support number 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.

If however reseating the memory or replacing it leads to a different error code or message please let me know, Although in that case the following may be helpful if you still have a blank screen.

Pavilion DV6, Black Screen and 3 Caps Lock Blink

HI,
I have an Hp Pavilion DV6 and I am getting the 3 blinks on the caps lock. When I turn on the PC it starts up, the caps lock blinks 3 times and the screen is just black. I have already tested the memory sticks, drain the battery, and hooking it up to an external monitor. Nothing shows on the other monitor and it just remains black. Please help!

Returned from vacation turned on my Power Imac G5 and all i get is 3 beeps a rushing fan noise , black screen and a blinking power light in a sequence of on, on, on, off.................on,on,on off...........

powered up my G5 after 1 week of shut down system beeps 3 times, with a black screen un changing, boot up with apple key and shift S no help. Power lamp blinks 3 times then goes out blinks 3 times again then repeats

I believe that with the Power PC that 3 beeps indicates that the power on self test found that no good RAM (memory) banks are available. How much RAM do you have, and how many sticks, what kind? Your RAM could have failed, or another possibility is that the RAM slot contacts are faulty, thus causing this power on test to fail like it would with bad RAM. RAAM is straightforward to replace (for either you or a technician in a repair shop), but if the contacts for the RAM slot(s) need servicing or replacing that is much more involved.

My HP Pavillion dv4 has a black screen and blinking Caps and Num lock

BEFORE anyone says to take out everything and press the start button for however many seconds, i've tried that. I've also tryed counting blinks, but there seems to be no pause in blinks, thus continuous blinking.
SO, recently i have updated my laptop, i let it shut off but i did not choose for it to restart. Today when i tried to turn it on, the screen was black, did not turn on and the caps lock and the num lock have been blinking continuosly, without pattern. The touch screen volume and such is also on and after a few seconds the fan turns on. There is no loud beep, just the regular startup soft beep. So, i would like to know, if anyone knows what i can do, before i have to go and pay to fix this thing.

i have took it to the apple store, i am out of warranty and they said it is a hardware problem, god knows whats causing the black screen it is fine when on as i got it fixed at a local phone shop but when the phone dies then there is no bringing it back to life.

Blackberry Z10 won't turn on after software update. Black screen and LED light blinking

Im using BB Z10 (stl-100-1 ) os version 10.3.1 for 9 months, recent days it hangs a lot and it hanged later not turning on and red led has been blinking simultanously. please help me

Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
With the battery inside, connect your BB to the wall charger
Leave it alone for 2 hours, no matter what the LED or the display does
Remove the battery
Wait 15 minutes
Insert the battery
Wait another 2 hours, no matter what the LED or the display does
This has been known to "kick start" some BBs. If it fails, please do it again but increase the step 4 wait time to 2 hours, and perhaps as long as 4-5 hours.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
Obtain access to a known good and identical BB...use your battery in it and see what happens
The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
Good luck and let us know!

Hi,
Check if this helps:
Restoring the BIOS
If it is blinking 3 times it usually indicates memory issue..So you can try reseating the memory modules or try one memory at a time in each slot..
Refer the links below:
HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot
Removing and Replacing a Memory Module for HP Pavilion g6-2000, g6-2100, g6-2200 and g6-2300 Noteboo...
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem

I tried to update my ipad software whilst connected to my computer. There was an error and now my ipad is frozen with a black screen and a white apple. it will not even power up. Help

I connected my ipad to my laptop in the hopes of dowloading some photos i needed. It invited me to back up my data and update to ios 7.0.6. After 2 hours to download the software it then tried to install it and encountered an error. The ipad is now frozen to a black screen and the apple symbol. i cannot even power it off. What on earth can I do?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- 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.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Also, do you remember what the error message said?

I have an iBook g4 14" 1.42 ghz. I recently installed a new hard drive. I put the install CD in. Then, I pressed the power button, then the "C" key. Black screen and No chiming. Please tell me, what I can do to resolve this? What is the problem with it?

Since it will not boot then a hardware test can't be run. You could try FireWire Target Disk Mode and if it works then access from another Mac to run tests on the new drive. You could also try installing the OS X software from the host computer. If this does not work then professional help should be considered.

Pro won't start. Instead get a black screen and a beeping every 2 seconds. LIght at front right corner of keyboard flashes in sequence with beeping.

If it is giving a single beep every two seconds, then it is not seeing any of the memory. You could try taking the back off, remove the memory module and reinsert to see if that corrects the problem. Or just take it to an Apple store genius bar and have the techs do that for you.
If you are uncertain about working on the memory modules, you can find on-line videos for doing so at OWC, http://www.macsales.com where you can see the procedure for your year, make and model of MacBook Pro.

My iPod has a black screen and when you press the power button nothing happens. Also when you plug it in the the computer or wall nothing happens.

My iPod was plugged in over night. When I woke up in the morning it had a black screen and wouldn't turn on at all. Also it doesn't say that its charging when it's plugged in and when plugged into the computer nothing comes up like it did before.

Reset it by holding the on/off and home buttons at the same time until you see the Apple logo (ignore the off slider if it appears first), then release. You won't lose any data by doing this.
