No sound in EliteBook 2540p

Hello, I have a strange problem with the audio. The system has windows 7 professional 64bit. In the "Audio Devices" window and the playback tab I see as the audio plays but I can not make it listen for notebook speakers or by headphones. The sound is not muted and is turned all the BIOS settings to the factory what is going on? Why not hear anything?
thanks

Elitebook 2540p sound - USB only

I have a Elitebook 2540p.
Just today the sound stopped working. Both the internal speakers and the headphone jack.
I've done the following:
* Verified that sound levels were correct
* Checked device manager
* Installed HP Support Assistant
* Updated audio driver
* Checked system F2 at startup
No issues were found, but sound still did not work either through headphone jack or internal speaker.
However, i just plugged in a USB headset. I get sound through the USB headset.
Any suggestions?

If they just randomly went off when you haven't done any updates or anything, then no.

Elitebook 2540p Motherboard changed. Integrated motherboard IDT audio device missing in windows 7.

Hi,
Old situation:
(I recently changed motherboard for my computer Elitebook 2540p. When i installed windows 7 to my computer the computer doesn't list any audio devices in device manager page. I've checked bios for any faulty settings and they are all set right. Theres no yellow marks in device list either and all drivers seems to be installed.)
New situation:
Installed windows 7 again and computer found / installed audio devices normally. I tested computer for hours to play audio from it and everything worked fine. I restarted computer several times / re installed battery to the computer. On one restart the computers audio quick mute button below the screen appeared to be orange and the sound speaker icon in windows was marked as X. I check device list again from device manager and there was no audio devices listed (No sound devices at all). After that i restarted computer and before the computer started downloadin windows i pressed the mute button and it turned blue. I then went to windows and sound devices / sound was working again.
Old situation:
I have motherboard integrated IDT audio device.
When i try to install audio drivers from hp site for 2540p i get "Your system does not meet the minimum requirements for this update." And the device manager doesnt list any IDT audio devices.
I then installed xp and the computer found IDT audio device normally and the sounds are working correct.
New situation:
After i did new windows 7 install and all my audio drivers installed / devices showed in device list / audio worked i downloaded audio drivers from HP driver site and installed them to the computer.
Audio problems has not been occured again after my HP screen mute button turned to orange / Windows sound speaker was marked as X / Computer didn´t find any audio devices.
Currently waiting if the problem occurs again and trying to think what would cause this ( Hardware problem or software)? And how to fix it permanently.
Any help for this problem?
BIOS is updated to newest version from HP driver download center.
All windows drivers are installed.

EliteBook 2540p integrated microphone not working

Recently I had to replace the hard drive on my EliteBook 2540p and since it came back from the shop the integrated mic seems to have stopped working.
Any ideas?

Hi.
I have a DV2620EA with exactly the same problem as yours. It seems as though this hissing background noise isn't a hardware issue (in most cases), but a driver issue in Vista. Instead of "updating" your sound drivers (i assume you have a "connexant HD audio driver"), remove them entirely first and then install them from "hp support and drivers website".
To do this;
- Go to the control panel
- Find "device manager"
- Right click "sound, video and games controllers"
- Select "properties"
- Click on the "driver" tab
- Click "uninstall" and check "delete driver software for this device"
- Click OK to remove the drivers
By now, vista should have no "record" of a microphone device on your computer. Check this by going onto sound recorder, it should show you a mesage saying "no mic detected on your system" (or something like that)
- After this, go onto http://welcome.hp.com/country/uk/en/support.html and type in your notebooks model number and find your audio driver. After the install, you should find that it works again, *it did for me*XD
Hope this has been of help.

Replace sata11 with ssd elitebook 2540p 17 2.13 low volt

Hello All.. I have a couple of HP EliteBook 2540P with I-7 ,2.18 GHz, 4.00 Gb, 1.8" 320 SATA11 low volt system that only supports a 1.8 SATA11 HD (unless I remove the dvd ) and want to upgrade to a 120gb (or larger) SSD.. Does any one know what I need to look for.. HP show two different drives.. One for the low volt 25a (Mine) and one for the std volt 35a.. I don't want to pay HP's price and need to know what to look for when I purchase a SSD .. Most SSD's on e-bay show they will work with any 1.8" HP laptop but before I order I need to know for sure.. If you have done this conversion I would like to hear from you ..The 1.8" pops in and out easily so that is not the issue..Just if the HD's are different..
Your help will be greatly appriceated..
Thank you.. Oreagle

Fingerprint reader not working on elitebook 2540p

I have elitebook 2540p, and I can't get my fingerprint reader to work.
The driver is installed and looks good at device manager.
I installed HP ProtectTools 5.12.754 and I can not see in the credentials area the fingerprint, only the smart card.
I tried also with DigitalPersona software and it's the same.
I have download the last driver from HP website under the correct operating system (Windows 7 enterprise 64bit).
I think the fingerprint reader is working since I entered the Bios and there it worked when I swept my finger. I saw the image of my fingerprint on the screen.
What might be the problem? why HP protect tool can not recognize my fingerprint reader?
Thanks in advance,
Ariel

I have the same issue with the same laptop
I've noticed that whichever driver you try and install, the version always seems stuck at 2.1.0.2

Hi There,
in the quick specs document for the HP EliteBook 2540p Notebook PC there is mentioned that one can only place a 80/160 GB Solid State Drive.
Why is it not possible to place for instance an Intel DC S3500 240GB SSD drive? This drive has more GB's and is faster...
How can I configure my elitebook that way that it will accept such a drive without losing maximum performance?
Thanks!
The laptop supports only 1.8" drives in the primary hard drive bay. I think that a 1.8" 240GB drive should work on the laptop. However, it can't be the Intel because it's a standard 2.5" drive and won't fit in. The manual says that you can use a standard 2.5" solid state drive such as the Intel one but only in a hard drive carrier (caddy/enclosure pn#
598787-001) instead of the optical drive (DVD-ROM).
Don't forget that the laptop supports only SATA II connection. This means that you can probably use a SATA III drive but it will work as a SATA II one.

SSD laptop upgrade for Elitebook 2540p

Can a 160-GB SSD, part number 602675-001 from a Elitebook 2740p tablet PC, be safely used in a Elitebook 2540p laptop? The 2540p's processor is an Intel Dual Core i7-640LM 2.13-GHz processor, (turbo up to 2.93-GHz), 4-MB L3 cache, 4 threads, low-voltage (25-W). The 160-GB SSD that specifically goes into the 2540p is part number 598782-001.

Hi,
It looks like both laptops use 1.8" drives and also Windows 7 64 Professional. If the drive fits in go ahead. If you get the none genuine message on Windows, phone Microsoft and reactivate it by phone.

Elitebook 2540p: Faint sound and static coming from speakers...Need Help!

I am having issues with my new 2540P. I can hear faint sound and static coming from my speakers as well as my headphones when I plug into the jack. I first started having this issue when I plugged additional speakers into the jack and USB while talking on Skype..
I am running Win7. I tried troubleshooting drivers and hardware, disabling and enabling, and a system restore going back one day...but no luck. When I disable the speakers, I stopped hearing even the faint sound. I also tried plugging and unplugging the jack 20 times.
Is it possible that this is a hardware failure (jack and/or sound card)?
Does anyone have other suggestions?

I am running XP and have same problem. Sound now gone after "pop". Customer services suggests hardware failure and send back to factory. Flashing BIOS and updating IDT audio driver will not fix the problem.
Possible speaker failure or audio chip failure.

EliteBook 2540p and XP audio

Hello,
I have got a 2540p but I can't get the audio drivers installed. The IDT High-Definition (HD) Audio Driver installer gets part of the way but then fails saying that there isn't any IDT audio hardware. I have checked the BIOS settings and the audio hardware is enabled and I have installed the Microsoft UAA patch.
It all works but no audio. Any suggestions anyone?
Thanks
Jonathon

Hi,
Install first correct MS-UAA for your XP system:
MS-UAA for XP with SP2 (required with a reboot before Audio, Modem and Graphic driver) here
MS-UAA for XP with SP3 (required with a reboot before Audio, Modem and Graphic driver) here
Only after that download and install:
IDT High-Definition (HD) Audio Driver here

"AMT Options" missing from HP 2540p BIOS "System Configuration" tab

I used to have an HP Elitebook 2540p Core i5. I recently got a Core i7 version.
The old machine had an "AMT Options" tab that could be used to set options to make it possible to see the AMT MEBx (Management Engine BIOS Extension) at boot time. This is shown in this picture:
My new Core i7 machine is missing this option, as shown here:
I need this option so I can enable the AMT serial-over-lan feature for debugging.
I updated my BIOS from F09 to F50 (the newest) but the option didn't appear. I went to the "Set Security Level" setting which seems to control what stuff is shown and what isn't. But it didn't have an AMT Options option.
Can anyone tell me how to get this option back? All HP Elitebook 2540p should support AMT right? Because this manual seems to indicate it:
http://h10032.www1.hp.com/ctg/Manual/c02958196.pdf
I also tried doing "Restore Defaults" and "Reset BIOS security to factory default" froim the "File" tab in the BIOS
(Also I tried just hitting ctrl-p repeatedly at boot to try and get into the MEBx but it didn't work
Thanks for any help you can provide (but I know this is a pretty hard/uncommon question)
