Hp pavilion dv4-2049us cpu not functional

Powered on successfully. Caps Lock and Number Lock LEDs blink once, meaning the CPU is not functional.
Replaced CPU with same make/model (AMD Athlon II M300) and have same error/problem.
Is this repairable or is it time for a new laptop?
PC support for the family

thank you for your input.
with the prices of a new MB vs. Cyber monday laptop deals, the choice was made for a new laptop.
as much as i enjoy working on PCs, this was an easy choice.
the broken laptop was an 'exclusive' HP deal from Office Depot/Max or whatever, about 2.5 yrs ago, and i think the new make/model will be an improvement.
plus, i'll be the one setting up everything, and will be able to add/remove the necessary software, etc.
thanks again

CPU not functional - 1 blink of caps and num lock

I have HP Pavilion dv4 Notebook
It started giving me blank screen with caps lock and num lock blinking, and I went to the HP support and found out that it has something to do with "CPU not functional" thing. I have to say this diagnosis is bogus and on HP site it says I have to contact HP support for this, and when I go to contact HP support they said my warranty has ended so I cannot even send them an email about it except come to this forum again post my grievance. It seems this error is happening to many customers, and if I remember correctly CPU is not something that will go wrong suddenly, maybe the motherboard or battery, but all hardware parts not the CPU. It seems there is a known issue with DV series of notebooks where this blinking is happening. To your surprise I'm now using the same laptop to post this while the lights are still blinking. The best place HP support directed me was either to pay for service or to contact recycling, REALLY? Is this really the award-winning support HP has. I am dismayed with the intricacy the site has in getting your problems heard by HP and get a resolution. So here I am asking for the community forum if they have fixed their laptops after getting the famous "CPU not functional" error.
And now before I submit this, the cpu fan has started to make very scary noises, just like a small motor bike, somebody please help me.

Follow the troubleshooting on this HP web document.

Hp pavilion dv6 cpu not functional

Hello,
I have a HP Pavilion DV6 and after I press the power button the display remain black and the caps lock/num lock LEDs are flashing 1 time. I saw the LED flasing code and the error is CPU nou functional.
Please help me to solve this problem.
Thank you.
Doru

normally the only way to resolve the issue is to replace the CPU, if the unit is in warranty then HP will do this free of charge
I would suggest doing the following 2 things first however:
Power drain:
remove battery and power cable
hold power button for 15 seconds
replace power cable only
power on
BIOS recovery:
hold Win+B and power on with these 2 keys held down
if the problem still persists after these 2 steps then the CPU needs replaced

Pavilion G6-2208CA Keyboard not functioning

Two days ago my laptop keyboard all of a sudden stopped working. Whenever I press keys, nothing happens. This came about all of a sudden, just one minute working perfectly fine, and then the next none of the keys are functioning. I've gone through several resets and still no functionality.
I've done everything I can as it was listed on the site. I uninstalled and reinstalled my keyboard driver, as well as both a PC refresh and a complete factory reset. I also saw to reset the BIOS, but I can't even open the boot menu with an external USB keyboard.
I bought the laptop refurbished off NewEgg less than a year ago, and it worked perfectly until now.

Hi @C-Alex ,
Welcome to the HP Forums!
It is a terrific place to find answers.
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I see that you notebook keyboard has stopped functioning, When you connected an external USB keyboard you could not enter the bios. This is most likely because Legacy devices have not been enabled in the bios.
As it is less than 1 year old, I suggest contacting HP support as it may be in warranty. They can check that for you and provide options.
Please call our technical support at 800-474-6836. If you live outside of the US/Canada Region, please click the link below to get the support number for your region. Phone Assist Worldwide
If you would like to replace the notebook keyboard yourself, I am sending a link to the HP Pavilion g6 Notebook PC Maintenance and Service Guide. Please not page 51 for a list of replacement keyboards and the procedure.
May the force be with you!

Pavilion dv4 Cd drive not working

Hi guys about two months ago my cd drive decided to stop read my my cds as well as to stop burning disc. Ive tried updating it and cleaning the eye and i know that its not the cds because they work on my desktop. the funny thing is that the drive does rotate the cds but it dont recognize it so the cds are in being rotated for like 3o mins and the laptop doesnt find anything. i dont know what to do and neither does my brother unfortunately i dont have the money to get a new drive so wat can i do ? PLEASE HELP

I had this problem too last year and contacted HP support and to my surprise, the customer support person started Googling for fixes
I did that myself and found the above fix. It then started working again. I then called back and informed them the fix myself

HP Pavilion g6 ATI GPU not functional

Due to the problems i reported in june with one of the pre-instaled programs (Skype) causing a BSOD, and the newest drivers for the laptop being very outdated, i have tried a lot of things trying to update my GPU drivers. After the issue was temporarily fixed (neither skype, nor sonix who turned out to have supplied the faulty driver, nor hp have done anything to actually solve it permanently) the system seemed to work normally.
However lately i've been noticing a lot of overheating, and applications running at substandard speeds, so i wanted to check on my gpu. As it turns out the device manager does not see the dedicated ATI Mobility GPU at all, and instead had been using the "powersaving" Intel GPU.
I tried reinstalling the original switchable graphics system from the HP site, because i suspected something might have been disabled there, as CCC was not available any more, but any attempted driver update from the SP53404 package fails to install the drivers for the ATI GPU.
What the hell happened? How can i get my GPUs and drivers reset to default conditions?
This question was solved.

Actually, never mind. After a restart (i mostly only hybernate), the ATI card was displayed again, and thus the installation of the drivers was successful.
Switchable graphics, the dedicated video card and all features of it are working again.

HP Pavilion dv4 1125nr will not boot up it says "No bootable device insert boot disk

When I power on my laptop it keeps saying "No bootable device, insert boot disk & press any key" but I don't have a disk. what can I do to get my laptop working again?

Hi
When your system starts press F2 at BIOS prompt and do a hard drive Diagnostics test to see if your hard drive has failed , You may get a failed short DST test which will Indicate hard drive failure . Is your machine under the 12 month warranty ??

CPU not funtional

My dv7 1135nr died a couple months ago and I finally got around to atteepting to get it back to a running state. The problem occurred when I booted it and it did not boot into bios and it gives me led error code 1 which means "cpu not funtional." Does this mean the cpu is dead or damaged? I have already reseated it to no avail. If anyone knows a little bit more information than "cpu not functional" on led error code 1, please share it with me.

That code means your CPU is dead or not receiving power from the system board.
Your notebook is new enough to still be in warranty.
Contact HP.

Pavilion dv4 memory/RAM upgrade

I have a HP Pavilion dv4 (15inch screen), not sure rest of the model #. It's on WIndows 7 Home premium 64 - bit operating system with 4 GM of RAM. I am looking to increase the RAM and wanted to know if anyone knows the maximum I can expand to and also if there is 1 or 2 card slots for the memory? Any help would be appreciated. Ideally looking to make it 8 GB or RAM if possible.

Since you do not know what kind it is I have to assume it is the oldest dv4 series, the dv4-1000. These use Core 2 duo processors and DDR2 memory and belong to a bygone computing era. The max on them is 4 gigs. Can you maybe identify the processor you have in the machine? This would narrow it down a bit. If your memory is DDR2, then 8 gigs of it costs an arm and a leg. DDR3 is much more affordable but not used until later models. The dv4-3000 uses 2d generation Intel Core processors and can take up to 8 gigs of DDR3 memory, for example All DV4s have two memory slots.

3F0 Error, Hard drive does not exist on Pavilion dv4.

I have a Pavilion Dv4 with windows 7 OS.
When I boot up the computer it tells me "No bootable device -- insert boot disk and press any key"
I have done the F2 system diagnostics and once I get there click the Hard Disk Test which brings me to where it says "Hard Disk Not Exist. Press <ESC> to continue" and prcoceed to hit Esc where it tells me the Hard disk test failed and "Boot device not found (3F0)"
After which I restarted and hit F10 to get to the BIOS which I then went to Diagnostics and tried to run the "Primary Hard Disk Self Test" and then it says "Hard Disk Not Exist" still. The memory test runs fine passes and gives me no errors.
I have also done a hard reset and have re-seated the hard drive and NOTHING has worked. Help would be appreciated because this has been happening for a VERY long time (just happened to be after the warranty ran out, convienent eh?) and I lucky had my fiances older laptop which is very old.

The notebook is not able to recognize the Hard Drive.
Are you shure that warranty of your PC has ended? Keep in mind that warranty starts from the date that you buy the PC.
If the Hard Drive test shows that the test failed, you will have to get it replaced. I suggest you to call HP technical support and get their advice on the available options for service.

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.
