HP Pavillion DV4-1225DX issues / fix thread

[ryofire]

dell-m4-1 will fix the internal speaker, though the internal mic will not function. on the other hand, with hp-dv5, the internal speaker will not function but headphones and internal mic will. so depends on what you need more.

The dell-m4-1 fix is still necessary in jaunty, but now the mic does work. Also the default ati restricted drivers work well enough. I'm finding a few too many stability issues with it though. Here's a quick list.

General instability and slowness with firefox plugins.
Skype works great... until it inevitably crashes.
Warzone 2100 keeps minimizing on me at somewhat regular intervals.
Warzone's sound occasionally acts really strange when the program is loaded it turns to static for a few seconds.

Hey all...
How about the video issue, have you got a right driver for it?
I tried some free-drivers and the proprietary one.
The proprietary works, but I don´t know why, when I open applications like Totem or when I open 5, 6 or 7 windows, the system slows down.
I tried ¨radeonhd¨ and ¨radeon¨ drivers too, but they did not work for me.

One point to note too is that the System Monitor shows that the processor is being strongly used with those visual effects, what should not happen. I don´t know if it´s true, but i´ve read somewhere that it does have something to do with the new X server.

Wireless seems fine to me.

How about the webcam, have any of you succeded with it?
And about the remote control?

Anybody have installed Ubuntu 8.10 in this laptop? Experiences in older versions? =//
Help plzz....

Keep the Video driver up-to-date... worked for me.

The audio stuff can be fixed (in hardy 8.04) by adding this two lines into /etc/modprobe.d/alsa-base :

options snd-hda-intel enable_msi=1
options snd-hda-intel model=dell-m4-2

I'm trying now to fix the Remote Control, does anyone can help? =/

Another possible audio fix.

I'll try it out after I get my laptop back from a warranty back-light replacement.


As far as the remote goes I never even bothered to try it. I guess I should look for the thing just in case I can find the time to play with it.


Also I plan on testing out Karmic before it get's released. Expect a cleaned up streamlined post on that subject come October.

Bad news guys. Your on your own for Karmic.

My laptop isn't charging. It's either the power adapter or laptop itself (no light, won't work without battery, etc etc). This is actually my third serious hardware problem with this machine. I hope this time they just blame the motherboard and replace the whole thing....

well time to back up the whole hard drive...

I've got 9.10 up and running now. I'll give more detail later, but for anyone out there thinking about upgrading heres my experience so far.

Sound works great out of the box (headphones untested). Wireless is broke out of box but I have it working.

The restricted drivers manager is useless. That said the manufacturers for both video and wireless have surprisingly good documentation.

grab the video driver from

compile the wifi driver from

Im running Karmic Koala too but my "integrated Microphone Array" isnt picked up by Ubuntu....it works fine in windows though. I have good output through speakers (have not tested the headphones)

My lspci -v output

Also...im running 64 bit...so i dont know why that says 32

I have quite the opposite problem: My integrated mic array is detected, but external mic does not work. Funny thing is that sometimes, my integrated mic array also stops working in Ubuntu, and does not work until I restart.
As for the 32 bit thing, I too am not very sure. I too use 64 bit Karmic, and my system shows 64 bit in some places and 32 bit in other places. My "lspci -v" output is:
