Pavilion dm4 Not starting

So, I was browsing the net, and downloading something... suddenly my laptop turned off, and it would have all the LED lights blinking...
I realized that the power cable was not connected, so I was thinking the battery just drained, but I dont remember any LOW BAT.notifications... So I connected the power cord and it did not help with anything... Still blinking on all LED's when I start it... it also starts the fans for like 2 seconds and then shuts down again ... after 5 seconds it repeats the blinking and the fan. ...
It does it continuasly... it doesnt blink only 1 or 2 or 3 or 5 times.. it goes all the time with all the lights and the fans.
What would be the issue?
I unscrewed the laptop and check all the connections on the hard drive, Ram, and also checked the motherboard bat,... it did not help.
Also I am out on the warranty...
What else can I do? What do you recommend?

Laptop Pavilion DV6500 not starting

I have a HP Pavilion laptop DV 6500 running Vista 32-bit.
The last time I used it, a week ago, it worked perfectly. When I tried to start it yesterday, all that happens is that all the LEDs ll flash once briefly and it does not start. I have tried the following:
(1) To boot it with only the battery;
(2) To boot it with only the mains power supply and with the battery removed, and
(3 ) With both the battery installed and plugged into the mains supply.
(4) I have done the above with a suitable new mains adaptor.
(5) I have disconnected it, removed the battery, and held the Power On button down for a minute.
When it is connected to the mains, the blue circle around the plug lights up.
Please help -- I am a pensioner and I need this laptop, and I really cannot afford a new one.

Hello flopez559,
Once you're able to actually boot up, we will be able to run some hardware diagnostic tests from your computer using the HP PC Hardware Diagnostics UEFI. Testing for hardware failures. After following the steps from that link, and you need to update the UEFI, click here.
Let me know how this goes.

Mousepad not responding Pavilion dm4

Yesterday evening I woke my computer up only to find that my mousepad no longer worked. I figured it was some glitch like the many others I have found already on this laptop (Sound buttons not wanting to work correctly, mute led light not wanting to come on, etc.) And was hoping to restart and fix the problem. Today, after restarting, my mouse pad still does not work and I, apparently, am not the only one having this problem.
My Specs:
HP Pavilion dm4-2070us
Windows 7 Home Prem OA
I have tried updating the driver (It said that the version that was linked to was the exact same as on my harddrive) and I have also tried updating BIOS with the same result. The mousepad IS NOT turned off. If it is the light no longer works on it as well and it is stuck in off mode. The mousepad is not showing up in control panel no matter what I do.
I'm getting tired of all the problems I have had so far out of this laptop since I've only had it since the middle of August. My friend told me that HP was much better than Dell so I went with her instead what my gut told me. I had been bragging to everyone how wonderful this computer was but now I feel like I should go back and apologize to all my friends. Please say this is an easy fix and I'm overlooking something quite obvious. I'd hate to completely turn my back on HP for a stupid laptop.
This question was solved.
View Solution.

As of right now I have resolved the issue. If anyone has a problem similar to mine, before you send it in, maybe you can try what I did. Last night I let my computer die completely then took the battery out for a few seconds. After that I plugged it in and let it charge a bit (Maybe 30 minutes?) before trying to start it up and try the mousepad again. It's working just fine now, the scoll and zoom in/out even seem to work a bit better now.

Internal Microphone not working on Pavilion dm4 Laptop

I have an IDT High Definition Audion CODEC internal microphone on a Pavilion dm4 laptop.
I was advised by an helpful HP support person to uninstall and re-install drivers and this I have done a couple of times.
Occasionally the microphone works but more often it is still not working from Start up. It is not working today!
I am trying to use Skype.
I have checked that the driver is up to date. ( right click on IDT in Device Manager) and this was confirmed.
I would be very grateful for any other suggestions.
Christopher

Thanks for the suggestion.
I opened the Sound control panel as you suggested and the Internal Mic (IDT) is shown in the list of microphones and has a green tick ( and is already enabled in properties). It is selected as a default device. ( the icon shows a picture of the laptop indicating the microphone on the lid not the picture of the microphone as shown in your clip)
In the Sound control window there is a sound indicator panel to the right of the internal Mic Icon that has a green bar that moves up and down - indicating that the microphone is responding to sound.
However it is still not working in Skype and it is the Internal Mic that is selected as the device here.
Very frustrating as I really would like to Skype. I tried uninstalling and re-installing Skype Version 5.5.0.117 and this has not made any difference.
Any other thoughts?
Christopher

HP Pavilion dm4. Windows failed to start. A recent hardware or software change might be the cause

Hi,
I have an HP Pavilion dm4-3114TX running Windows 7.
The laptop went to sleep during a windows update then froze, so I pulled the battery out to restart it. Each time it restarted it kept taking me to a grey screen. I've tried F8, F2, F10, F11, going to advanced settings and no matter what I click on it takes me back to the grey screen with no options (the cusor does move though). It did let me run memory tests though and they seemed to be fine.
I then pulled the internal hard drive out (probably shouldn't of done that) and put it back in. It does the same thing, only this time it's a black screen (cursor moves but is over sized).
I've got file's on there that I do want back, but at the point where I don't care and will wipe it all to factory settings, but unable to even get to those options. I have brought recovery disc's but they don't seem to help either.
Any help would be much appreciated,
Thanks.

Hi @DannyLongLegs ,
Welcome to the HP Forums!
I would like to take a moment and thank you for using the forum, it is a great 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 First Time Here? Learn How to Post and More.
I understand that while doing a Windows update the computer went to sleep and then froze. You removed the battery to restart it but you only get a grey screen.
You were able to access the diagnostics and test the memory and it was fine. You removed the hard drive and reinstalled it.
Now when you boot up you have a black or blank screen but it is oversized.
There are some recent Windows updates that have been causing some issues.
First I would try to boot into safe mode to remove the most recent updates. Please look for these and remove them if found.
KB2982791, KB2970228, KB2975719 and KB2975331.
Another program that may be causing this issue is "Search Protect" if that is located please remove it also.
Entering Safe Mode (Windows 7)
See which Windows updates are installed ( from window.microsoft.com)
Here is a link to Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot
If the issue is not yet resolved I would do a recovery back to factory. Performing an HP System Recovery (Windows 7)
During the recovery process you will see an option to backup your personal files to prevent loss. As you stated you have files you would like to retrieve, I would do the backup.

HDMI not being detected on Pavilion dm4

Hello, I have a pavilion dm4-1165dx and for some reason my laptop won't detect the hdmi cable when I have it plugged into a tv. I have done this before and the labtop has connected and I was able to connect my xbox with the same cable so I know it's not that. Also when I open Intel Graphics and Media Control Panel for some reason under the display tab and subsequently under the Monitor/TV settings tab it says Monitors/ TV settings not supported, but I've used this before to connect it to the tv. Thanks for your help

>I have done this before and the labtop has connected
Did it work with the same hdmi cable?
Sometimes it's a cable quality problem.
Have you updated the graphics driver?

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.

My laptop ( hp pavilion dv6-6b27nr entertainment PC) willl not start up. the screen is blank.

I have a HP Pavilion dv6-6b27nr Entertainment PC (Win 7) It would start up with the message "BIOS RECOVERY" . It then would not start up at all. I took it to a repair shop, they contacted HP and got it working. i took it home and it worked just fine the same day, however when I tried to use it the next day the screen is just blank. i tried the take out the battery process with no effect. i then tried tapping the f11 key at start up. the fan came on and it made some noise, but has failed to show anything on the screen. When I turn it on the caps lock key blinks continually in a sequence of two blinks. (When i brought it home from the repair shop I downloaded malwarebytes and quarantined 87 pups etc. )

HI @owe ,
Thank you for your query, I will do my best to help!
I grasp that you received a bios error and the notebook would not start. You took it to a repair shop, who contacted HP and got it back up and running. When you took it home it ran fine. You downloaded malwarebytes, installed and ran it, and quarantined 87 pups etc. When you tried to use it the next day you get a blank screen and the lights blink twice.
Here is a link to Computer does not start and the LEDs blink or the computer beeps . Two blinks again refers to the bios.
You should not be having a bios problem so soon after just having it repaired.
There may be a hardware issue that is causing this and I would test the hardware rule that possibility out. Testing for Hardware Failures (Windows 7, Vista)
If you are still unable to determine any problems, you would have some options.
You can try to restore the bios yourself. Restoring the BIOS
As you just got it back from the repair shop, you could take it back to them to see what they say.
As you stated that the repair shop called HP, you may be able to acquire a reference or case number to refer to and call them yourself. Just to clarify you do not need the case number to contact HP support but it would allow them to more easily locate any case notes from the previous call.
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

Pavilion DM4 doesn't start after motherboard replacement

My wife accidentally left her Pavilion DM4 in our RV with the roof vents open during a recent storm. Not surprisingly, it didn't survive the watering. We shipped it to the Best Buy service center for assessment and they claimed that the motherboard is fried and that they couldn't order a spare one anymore because "the model is too old." I ordered one on eBay that was supposedly pulled from a working unit and swapped it myself (transferring the old processor to the new motherboard). Unfortunately - despite all the drumrolls I was able to simulate - it didn't wake up after surgery. The HP logo on the back of the display, the orange LED on the f12 key (Wifi antenna logo), as well as the green LED built into the power button all blink in 3s intervals.
There is a white LED next to the power plug and if I put the battery in that LED turns orange. So it seems like the power supply works and is charging the battery, right?
What else could it be?
Any suggestions?
Thanks!

Dear Mrstenter,thanks much for your response! I tried a master reset, as well as reseating the memory and HDD - no change. There is no audible noise of any kind (no beeping, no fan, no HDD spinning).And unfortunately the blinking I'm experiencing doesn't match any of the error codes listed in that document. It just keeps blinking briefly every 3 seconds and doesn't stop.I left it plugged in and the orange battery charging light had changed to white when I checked it after a couple of hours. So I think the power supply and battery charging unit is working. If it was a problem with the display connector I'd think that the blinking wouldn't be as persistent and I'd hear the HDD spinning up. But as it stands it seems like it just doesn't come to live at all. The motherboard came from a vendor who prides themselves with "no DOA" policy and they claim it came out of a new laptop (which sounds strange, but it actually looked fairly new). But of course nobody can guarantee that (I'll try to return it if I can't get it to run). My biggest concern is whether the processor is still intact. Is it possible that it died too during the water damage? Does anyone know what the continued blinking means? Thanks,Martin

My HP Pavilion dv6-3060sa is not starting up on power plugging. Removed Battery Tried Hard boot.help

HP Pavilion dv6-3060SA is not starting up, tried hard boot but still no solution. The charger is OK. The problem is no LED blink on power connect as well no starting up of Laptop. Please help.

If you have another Mac, use Target Disk Mode. Connect your Mac to the other Mac using a Thunderbolt or FireWire cable, and hold down the T key while booting up on the problematic Mac. If you go into Finder on the other Mac, the first one's hard drive should show up as a disk.

Hp pavilion dv2500 laptop does not start -Pls help.

Hi,
I have HP Pavilion dv2500 laptop which I bought from US(before 3 years) and using in India.
It has Windows Vista installed on it.
It has been very frequent that the laptop does not start. Today my laptop started after 10 days or so.
It does not give any error when I press the start button. There is no change in the screen as well.
The CPU light blinks. The power light also blinks. But the HARD DISK light does NOT blink.
If I keep on hitting Escape/F10 key then sometime it may start.
Before two months my battery was giving some problems and it used to finish very early. So I had to always plugin power chord to use laptop. Then I started getting above problem. However I bought new battery. But then also the laptop start problem exists.
I called one of the guy and he says that I need to replace the motherboard which could cost around 8000 / 9000 INR(160/180USD)
Is it hardware problem? I am not sure if it's some other problem.
Any help is highly appreciated.
Thanks in advance.
Best Regards,
Purvesh

Try my hard reset method.
1) Remove the battery and unplug the DC power adapter.
2) Press and hold the power button for more than fifteen seconds.
3) Plug in the DC power adapter (leave the battery out for now)
4) Press the power button
Please post your positive or negative results here in your thread.
Best regards,
erico
