Help! Power trouble- pavilion Dv4

I'm a broke college student that saved up money for a good laptop. I bought a pavilion dv4 within the past few months. Just today, I had it on, working perfectly fine and left for work. When I came home, the power light was blinking but would not turn on no matter what I pushed. I plugged it in to charge it, assuming that was the problem. No luck. It makes a weird sound every two seconds and blinks. I researched it, and it said a lot about battery issues with that specific computer. I rarely shut it down. Did I overheat it or something? Please help, leaving for college in a far away state from home and need a working computer!

Unplug the power cord, remove the battery, hold the power button down to 30 seconds, connect power cord Only, see if it will power up.

Hello Loydgraf,
I understand you state your computer will not power on, is that correct? I will do what I can to help you.
When you have the computer connected to the AC charger only the small indicator light for it does it still go off after you press the power button?
Can you please provide the full make and model of the computer you have, If you are unsure where to locate that information have a look at this link for help if needed.
Please respond back at your earliest convenience.
Thanks

HP Pavilion dv4 notepad not booting. NEED Help!!!

Hi There,
I have HP Pavilion DV4. For some odd reason, when I turn on my notepad, I just get one flash of power light, volume indicating light, num lock light, caps lock light, and screen stays blank. Notepad doesn't boot but power light keeps flashing.
Initially I thought maybe my battery was low, so I plugged in the AC adaptor overnight and in morning it behaved the same way. I have tried all solutions suggested in blogs all over (including removing AC adaptor and battery and hold down power button for a minute, etc.) I am still not able to get my notepad to turn on. I have even tried to have it plugged in for few days, but I get the same thing from it.
I would greatly appreciate it if someone could help me out with this issue.
Thanks.

Have you tried to start it with just the power adaptor connected and the battery removed? Have you disconnected all external devices that may be attached to the notebook?

Hi @ibalpha ,
Thank you for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about your HP Pavilion dv4 Notebook and issue with the Boot time. I would restore the BIOS with this document selecting the reloading the BIOS default settings. This should restore the quick boot option in BIOS.
Hope this helps.

HP pavilion dv4

Hi, I have a hp pavilion dv4 laptop and I'm having trouble with it charging. I took the laptop to a local computer store and they tested the battery and the adapter, and both where fine. So that leaves me to believe it is a problem with the motherboard or the slot the adapter plugs into. When the laptop is connected with the adapter the light on the pannel lights up and when I turn on the laptop it has the charging symbol in the tray. Unfortunately the laptop will die in a few minutes. The laptop is no longer under warranty so some help would be greatly appreciated.

Hi,
First, try a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for a full minute. Re-insert the battery, plug in the AC Adapter and see if the notebook will start.
If it still doesn't start, is there a sequence to the 'blinks' that you can match to the table below?

I would say its just a conicidence and recommend you to do a system restore. As its an intermittent problem, you never know if you face same issue once again.

Hp pavilion dv4-1123us Media Card won't read

I have a hp Pavilion dv4-1123us laptop that won't read a 16 GB SDHC media card. The card works in my PC, so the card is good. I have a Scandisk 5-1 media reader hooked to my home PC that would not read it but I found through Scandisk site I needed to download the latest Firmware which I did and now the card works on my PC. The reader has always and still does read a 512 MB and a 2 GB XD cards on my laptop. I am running XP Pro OS.
I have searched the HP site for driver downloads but only see them for Windows 7 and 8 not XP.
Can someone help me on this?

Hello wgray826,
You’re having a problem not being able to read a 16GB SDHC card.
I think that your computer does not support the SDHC card.
Here is a link to your user guide and what cards it supports.
I noticed that it shows the Secure Digital but not the Secure Digital High Capacity.

No sound when using HDMI to Vizio TV. HP Pavilion dv4-4310us

I just bought a Vizio HDTV and connected to my HP Pavilion dv4-4310us Entertainment Notebook. I have it connected through the HDMI output on the laptop and get great picture, but no sound! I have scoured the forums for Win 7, and here on HP's site...tried a few things but it seems I'm having a different problem than others. Other people have posted that they had sound before and now have no sound. This is my first time using the HDMI output to a TV... I'm running Win 7 Professional, the Audio is IDT, and I have all updated drivers for the Intel 4 Chipset, and the IDT Audio CODEC. I'm hoping someone can help with this! It's very frustrating. Thank you in advance.
Michele

Yeah. It kind of *****! But it is true, HDMI does not transmit sound, just video. Which it does well I must say.
What I did is I have surround sound and I plugged a cord that has male connectors on both sides and I plugged it into my amp on one side and my mcbook on the other, so now I can get sound onto my surround sound and also get the video images on my HDTV. =) If you have a surround sound system with an amp, I would recomend doing this. Its easiest.

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.
