HP/Compaq :: 6930p "Core2Duo Whine Noise" Has Been Resolved- Without Disabling Speedstep
Jun 12, 2009
I just got a new Elitebook 6930p and its a fantastic laptop other than the dreaded "CPU whine" as some call it. Most uneducated people believe it is the CPU that makes this noise but in reality this has NOTHING to do with the CPU. Its the power components like capacitors and coils that make the Piezoelectric Effect which causes the noise.
I could not bear the whine noise after a few days so I took matters into my own hands. Sure I read about stopping the C1-C4 states in Intels speedstep but thats not a proper solution IMO since battery life will suffer. So how can we mask or cover up this annoying noise? How can we seal it inside the laptop so it does not reach our ears? I have the solution!

Seal it up all the power components with silicon sealer. Silicon sealer is perfect as it does not conduct electricity. These components do NOT generate any heat either.

I ordered and received my Acer 1410 (Celeron SU2300, WD Scorpio Blue 250GB, Windows 7 64, 2GB RAM) a little over a week ago and while I like almost every aspect of it, I'm wondering if the high pitched noise / whine I'm hearing from it is normal?
Basically I only hear it when there isn't much noise around, but it's still mildly distracting. It mainly comes from the area near the indicator lights, but is most apparent under the laptop where the RAM / HD slot is. For some reason the sound is much louder with the AC adapter plugged in. On battery, the noise is basically gone (but will come back for short periods of time). I can also hear the whine through the headphone jack if nothing is playing (at least on AC power).
What might be the cause of this noise and is there any way I can get rid of it? The RMClock trick doesn't work since the option to "Run HLT command when OS is idle" is grayed out and cannot be selected.
If I decide to return this and get another 1410 later (since the online store I bought it at is sold out right now), would I be likely to get another one with this whine/noise?

how to control the fan on the HP6930P?
I disabled "fan always on AC" in the bios.
The fan is always on. It doesn't disturb at the lowest level, but it ramps up every 5 mins or so for 2 or 3 seconds. I find that ramping up disturbing and would like to disable it. Considering how cool the air coming out is compared to laptops I have had in the past (Thinkpads and Toshiba) I would say HP is being conservative with their settings.
Is there a program or some bios setting?

I want to ask something about these laptops:
- Which one has better build quality?
- Which one has better display?
- Which one has better keyboard/trackpad/trackpoint?
- Which one is cooler and more silent?
Has anyone used both of them? Has anyone switch from T400 to 6930p or vice-versa?

I'm aiming to buy a new HP EliteBook 6930p in January 2010. There are a few issues that I've read about which concern me, however.
Some of these I have read have been fixed, although I haven't seen much in the way of confirmation of this. So I'm wondering, of these, have any been fixed in the latest production models of the 6930p?
1) The lid takes too much pressure to shut and/or doesn't stay shut.
2) The battery is loose when attached (any danger of it falling off?)
3) CPU whine -- I'm planning on getting it with a P8800 and ATI HD 3450 256MB, if that matters.

I'm a potential 6930p buyer. I really want to know is there a big difference in picture quality between LED and non-LED screens ?
I would like to buy a model with dedicated gfx and 1440x900 screen but I would settle with lower resolution screen with LED backlight if it's better than higher res one.
By better I mean better viewing angles, brighter, better colors, etc.
Is it worth getting LED based screen on 6930p ?

I just swap out the the motherboard for a working one and change all the components inside and the monitor don't power on. All the lights show the fan spins but no picture. Before I did the motherboard swap the same thing happen. The shop I took it to said it needed a discharge from the build up over time. After the unfix-able corrupt bios problem I was force to swap boards. How do I do the static discharge? I ground myself with a steel pipe took apart everything put it back together still the same.

I bought HP 6930p with ATI graphic card, WIN 7, and connected to the external display 24" (1920x1080) trough VGA port. There is a very noticable blurry and annoying image on external display. I tried different settings, but nothing did not help. Is there any solution to this problem? could be my graphic card or vga output damaged? Since with my 4 years old toshiba notebook, image was clear.
Has anybody docking station and is DVI output working fine (clear image)?

I'm looking for information about upgrading capabilities of my 6930p.
Now it has Intel T9400 (CPU-Z tells: Socket P (478) ) processor, which is very good, but not best.
Since I purchased Intel SSD 80GB Gen 2, I noticed that performance of my notebook is limited by processor (it has 100% load while my Win7x64 boots up or while loading some big application).
I found several options for mobile processors which support PM45 chipset and Socket P:
QX9300 (12M Cache, 2.53 GHz, 1066 MHz FSB) 45 Watts
X9100 (6M Cache, 3.06 GHz, 1066 MHz FSB) 44 Watts
Q9100 (12M Cache, 2.26 GHz, 1066 MHz FSB) 45 Watts
Q9000 (6M Cache, 2.00 GHz, 1066 MHz FSB) 45 Watts
T9900 (6M Cache, 3.06 GHz, 1066 MHz FSB) 35 Watts
My current:
T9400 (6M Cache, 2.53 GHz, 1066 MHz FSB) 35 Watts
One seller on eBay told me that QX9300 will not work in my desktop without giving any reasons. This fact confused me and I wondering which processors will run in 6930p?

Does 6930p come with a LED backlight WXGA+ (1440x900) screen? I read somewhere that it would come with a LED backlight WXGA or a CCFL backlight WXGA+.
2nd question: What are the differences between a refurbished 6930p and a canceled order one? Is there a chance to a canceled order 6930 be marked as refurbished?

I was looking at the new Elitebooks today and saw that there are now 8xxx series machines with 14" screens and that there is not a 6940p. Is the 8440 intended to replace the 6930? Also, why is the screen on the 8440x 14.0" rather than the 14.1" size that appears to be the norml? Another change in aspect ratio?

I'm thinking about buying the HP 6930p Elitebook. One concern I have is that it only has a VGA port and no DVI, HDMI or Displayport for connecting an external monitor. I plan to connect the laptop regularly to a 24" display.
I thought one workaround might be to get a docking station for the laptop, which has a DVI connection. As the laptop connects to the docking station via a different port, I assumed a digital video signal would be sent. However, when I called HP to confirm if this was possible, they advised me that as the laptop only outputs VGA, even when it is connected to the dock, the only thing I could do would be to connect it via the dock's VGA port; it couldn't be connected via DVI. Is this correct? I have received incorrect info from HP and Dell on more than one occasion, so I wanted to check on here. Would the DVI port work on the dock or could I only use VGA?
Also, if not, how much better would a DVI or HDMI connection be versus VGA for that size of display.

I just got a new 6930p. It's rather warm on the left side where the palm would rest and causes a rather big discomfort.
Is there any type of cooling pad that would cool it down?

I am using a un2400 wwan UMTS modem on my HP 6930p (WinXP, SP3) and noticed that it is automatically deactivated when the battery isn't inserted into the laptop (PIN Code is also deactivated on the SIM card). Once the battery is installed, it works without any problems.
Can anyone confirm this being a normal issue with this modem?
(the Huawei EM770 modem on my eee 1000HG works with or without an inserted battery but it also doesn't require the firmware to be loaded first, so maybe these two can't be compared..)

Since she only uses it for office, mail, web browsing and some music with Media player or iTunes, I know the integrated Intel GMA4300 will suffice.
However, I'm not sure about the processor. There are three options, a celeron dual core (which is really low-end, so out of the question), a 2.1 Ghz pentium dual-core (T4300) with 1Mb of cache and a 2.2 ghz core2duo (T6600) with 2Mb of Cache. They all have 4Gb of RAM.
Both the pentium dual core and the core2duo come with Windows 7 Home Premium (64bit) so I expect even the dual core can't be that ancient as far as architecture is concerned .....

A friend just picked up one of these but wanted to know if the heat issues she keeps on reading about are resolved.
There was some talk about a redesigned cover to better manage air flow but i cant find anything about Dell actually shipping them out.

I have a 2ghz P-M, 2GB RAM, 7800GTX equipped XPS M170 and never really took attention to this. It has CPU whine, and when you scroll webpages, it slows the scrolling process and emits the higher pitched intermittent whine until you stop, then it resumes a lower volume whine.
It's not really noticable unless in a quiet situation, but it's very annoying to me in such situations, especially because it limits the scrolling speed of pages and things in programs.
I've reformatted several times and i'm pretty sure its either the CPU or GPU whining. Gaming eprformance is unaffected.
Can I call Dell and have them do anyhting about this? I don't have Bluetooth, as some other topics have said works, but I don't think I should have to buy a module to have my CPU stop whining.

I have a brand new 12" Acer TravelMate 6293. I've instaled XP, Vista, Win7 and Ubuntu.
In all of them I'm having problems with the keyboard. It works, it's just sometimes it misses out on button presses, like you type a word and its missing a letter etc.

I just run some test on my my Z46 (P9700 2.8Ghz) and found there is something unusual.
I set the Vista power manager profile to high performance which suppose to give me the max speed of the CPU settings and I check with CPU-z and the reading was 2793.2Mhz which is correct ... however when I try to run some CPU stress test it CPU-z shows the multiplier jump back to x6 (suppose 10.5) and the core speed reduce to 1.6Ghz. And then I start notice whenever I have the CPU on full load it will switch to 1.6 Ghz instead of 2.8Ghz...
I tried it with different software and same happen.. I also monitor the temperature and it's only 65-68 which is normal to me...
I just can't figure out why the CORE speed would drop when it suppose demand the highest speed..
Is it just my Z46 or anything have the same happen ?...

I've decided to purchase an HP 6930p. I will mainly be using it for business - Word, Outlook, the Internet, Excel etc. I won't be playing many games on it (if any) or be doing any video editing. I have a 24" display, which I can use for any graphics work (Photoshop etc). I'll be using the laptop about 50% of the time away from the office - at libraries, coffee shops, or other offices/meeting rooms.
I'm trying to decide which resolution to get - the WXGA or WXGA+. I know a lot of people on these forums recommend the higher res screens; however, I imagine a lot may use their systems for games, video editing, CAD, web work etc. I'll be doing intensive office work. For a 14" business machine, what is the best resolution?
Also, if anyone happens to be a 6930p user, is there any difference in brightness between the two screens? That could be a factor.

Here is a brief description of my problem. I have a e1505 w/ a Core Duo (1.66GHz, T2300) My power adapter is reported to me "unknown" by the laptop. (total BS as i know the thing works) and then QuickSet tells me my battery needs to be replaced (this was too soon, so it leads me to believe that the power adapter did something to the battery) But I can't replace those right now. So i'm stuck at a multiplier of 6 (and yes i've disabled all the power saving features in the bios, but the wired thing is windows reports the real speed while other programs such as CoreTemp and CPU-Z report it at being just under 1GHz?)
And to get these things brand new would cost ~$120 (battery and adapter) So is there anyway I can get around the stupid limitation dell has imposed until i can find replacements for these? And, where is a good place to get replacements that won't cost me an arm and a leg?

I received an Inspiron 17r SE and have had absolutely no technical problems running it. The only thing that i don't understand is why my battery adapter whines whilst in sleep mode. This never occurs when the laptop is shut off or running but only when in sleep. The high pitched whine seems to oscillate with the blinking white light on the front of the laptop.
