Re: my laptop is still producing tghe murmuring sound
The Type of sound you mention can really be only two things, either it's a fan that's loose, or on the way out. Or vibration caused by something that is loose either inside or out. Do a cursory check by applying a small amount of preassure, "just the weight of your hand should be enough", Over the laptop while it's running, paying particulsr attention to the hinge area and the area around the perimiter of the nootebook. If it stops, there may be a loose fitting or screw someware. If it's internal you would do better if you let the manufacturer look at it. The bios should not have anything to do with it as noise is an indication of vibration, or a bad component inside.

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall.
ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time.
Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.
Check your system with external speakers, if it gives same problem its mean that the audio drivers od the system gone corrupt, needs re-installation,
if the system gives the correct sound, means that the speakers gone damaged, need repair/replacement, you can do by your self if you are technical enough otherwise you need technical assistance from Dell Support
This is a generic issue with all Windows OS updates....many of the users are facing this issue....this issue began after an auto update from MS changed many IRQs of Win OS, mainly the Sound and Audio Control system of Windows. 1 - R U facing NO Audio / No Sound issue...? 2 - Is ur Volume Control not responding ? 3 - Is ur Sound and Audio Device in Control Panel Grayed out ? 4 - Do u get a msg "No Active Mixer Devices Installed....when u try to open Volume Ctrl etc etc ?
If ur ans to any one of them is Yes...then u are being spammed by Microsoft....as ur Sound Control IRQ is being frozen by a recent update from Microsoft.... NOTE..THIS…IS…VERY..IMPORTANT... No file update or any sound driver update can fix it, neither Microsoft is issuing any patch to fix it…or giving any help on this. Full solution is available in my website (Support page)...it's quite simple process to fix it, and I am not charging any money, just doing FREE service to help everyone affected by this stupidity from Microsoft. www.sureshayyar.110mb.com visit my Support Page. many of us are victim of this “stupid” update, my office has 24 PC/Notebooks and almost all of them got this issue one by one in 4 months time period, I head the tech dept here. all the best... Kindly leave a feedback/rating to this solution as it will help me understand if my solution worked
The murmuring sound is in all probability a Hard Drive noise... I had a similar problem and the solution lies in the BIOS.. at startup press F2 or the Del key to load into BIOS... in Bios you will need to look you way to an option for the HDD devices.. In my BIOS I had a option for an acoustic quiet mode which stopped the sound eminating from my hard drive
Note that all BIOS versions are different... If this does not solve the issue then please post the make of your laptop along with the BIOS version
