HP/Compaq :: Envy 15 Fixed Multiplier (x7) On Battery
Dec 23, 2009
My Envy has the i7-720QM processor. I noticed significant reduced performance when running on battery.
RealTemp, Sandra, i7Turbo, Intel turbo boost monitor, cpuid, etc.. all report the multiplier at 7 (~930MHz), and won't move from there no matter what I do on the machine.
The multiplier seems locked/fixed at 7 regardless of load. As soon as it is unplugged it dives to 7.
I've changed the power plan to high performance and set min/max power management to 100%. This made no difference.
Is the BIOS forcing this? I believe 7 is the low frequency multiplier but shouldn't this kick in only is there is no activity (to save power?). If I am doing work, I expect the processor to at least run at the minimum frequency specified.
This behavior has been confirmed now by other members of the forum. Previos BIOS releases (F.05 and F.06) have been tested and showed the same issue.
I attached two screenshots, one the system running on power, and the other one on battery. Both running prime95 small FFTs.

i've had my Envy 15 for over two months now and although i don't use it frequently enough my wife noticed that on a full charge, unplug then the next day or so the battery is drained.
Basically here is what she does:
she would charge the laptop up
unplug then use it for like 20 mins
shut down Start>>shutdown
CLose lid
About or two days later she would try to use it and the thing wont turn on. Plug in the brick and voila! thing comes up.
Is she not shutting down properly? or is there some program on sleep eating the battery?
Or is that the rate this battery drains?
this is still on the FACTORY image, i didnt rebuild it

looking at purchasing one from futureshop, getting a decent discount, it has the i7 6gb of ram, 4830 graphics. It comes with both 6 cell and 9 cell, my question is, that is there anyway for me to get 3 hours from the 6 cell battery, with just office and wifi. Is there a way to underclock the processor a lot to do this, disable cores temporarily

How much time does it add to the Envy?
Will the laptop automatically switch from the 6cell to 9cell when the 6 runs out?

Now I haven't used my notebook on battery very often but judging by reviews and battery use here and there I do believe HP could've done better with designing their battery. I mean they can achieve up to 24 hrs with an elitebook (given its like a battery slice plus sticks out in the back) but don't even get close to a proper battery usage time with the standard battery. I've read reviews where the battery runs about 2hrs on battery and even some around just an hour, and that really is sad. I know the MacBook Pro was able to get about 7-8 hours out of a thin-n-light(given crappy hardware) so I know hp has the resources and capability to make this new battery. At least bring it out by the time the next gen Envys will come out and make sure these batteries will be backwards compatible with older Envys as well. Besides the battery life and locked multiplier I love my Envy

Does anyone have the Envy 15 along with the additional slab battery that connects to the bottom? Anyone found a sure proof way to connect it?
I latch the latches, battery is secure... However, it still says that the 2nd battery is not found. Move it around a bit, and then its there.... Wait, then its gone...

I just got a new envy 15 the other day. There is a high pitched noise that is kind of annoying, but I'll be using the laptop at a cafe 90% of the time and probably won't notice it. I'm pretty happy with the laptop otherwise.
Does anybody have any tips on increasing the battery life? Other than screen brightness and lowering the "maximum processor state" in the power plan, are there any other settings i should be aware of? I've read posts claiming to have increased battery life of an i7 envy 15 to 4-5+ hours. I think I'll be pretty happy if I can squeeze 3+ hours on my i5...

Playing an SWF (flash) file with video embedded in on AC power looks great. When unplugging the power and working on battery, the same video becomes very sluggish and unwatchable.
I've checked all power setting and ATI control panel and changed all "Optimize video on battery" I could find.

I spent a couple hours reading through dozens of pages in the 3 separate HP Envy 15" Owner's Lounge threads and couldn't find a definite answer to the following questions--there was usually conflicting info.
In total there's over 1k pages, so despite considerable time spent perusing and searching perhaps I missed a definite answer somewhere in there. So hopefully, it's okay if I ask this outside of those threads for a conclusive answer:
1) Every review I've read mentioned the heat issue with the i7 system. Has anyone read an official review or gathered a consensus from users if the i5 version of the 15" model has lesser heat issues?
2) Does the i5 have graphics switching? And does the i7?
3) The i7 has very short battery life, which dissuades me from getting it. Is the i5 any better? What sort of usage are most i5 owners getting out of it?

I heve T9500 penryn processor with 2,60 GHz and the CPU-Z is showing sometimes 13.5x multiplier =2.7GHz (without any undervolting software or lite that)
The RMclock showing 14x multiplier like IDA and CPUgenie only 13x multiplier
what that means, Is it possible to have 2, 7 when it is only 2, 6 GHz?

Laptops been working great for years.
Finally put Windows 7 x64 on the other day and I didn't notice at first but after a few weeks I started realizing the thing just isn't as fast for normal tasks as it used to be.
I remember I used to run speedswitch for XP back in the day and it maxed my CPU clock all the time. It obviously doesn't work for 7x64. So I loaded up CPUZID to check things out.
Basically the key reading is:
Current MHZ: 1595.54 Current Multiplier: 8x
Original MHZ: 2000 Origina Multiplier: 10x

I'm deciding between Dell XPS m1330 and the Sony VAIO SR, and have been slightly leaning towards Dell! yay! However, I'm kinda worried about the GPU problem I've read about. So I was wondering if I buy the XPS m1330 in say June (I'm going USA for college then), will I have the NVidia graphics card which does not have a design flaw? And also, about the heating issue, has Dell done anything about that? Or will I have to do the copper mod thing if I buy this laptop?

I think. Ran Prime95 with 8 threads and CPU-Z reports 1.7291 GHz consistently with 13x multiplier. Screen brightness was on max. Is there a GPU test I can run also?

My new Latitude E6500 has been suffering from a "stuttering" problem. The symptoms:
1. When watching videos on the web (CNN.com, for example), the video and audio would stutter and pause, with "breaks" occuring multiple times a second.
2. When moving windows around the desktop, they would jerk along rather than gliding smoothly.
3. Most windows and programs would open slowly (for example, opening the control panel would take several seconds).
4. Task manager would never settle down to 0% or even 1%, but rather bounce along at 2-7%.
I tried re-loading the OS (Windows XP SP3) from scratch. Drivers, etc. Three times. Same problem.
Things seemed to run fine without Control Point software, which I was prepared to dump--but I do like some of its features.
But I discovered that choosing a Control Point power managment scheme was the problem! The solution was to select a regular old Control Panel power managment preset (one without DELL in the name). Problem solved! Task manager now settles down to 0%, videos run smoothly, etc.
My E6500 specs:
P9500
4GB RAM
Nvidai 160M
260 GB HD

I've just got a Sony VAIO CW2 with a GT 330M GPU and have read that the chip is throttled from the default settings.
The source is a review at http://www.notebookjournal.de/tests/...w2s1-nkrt-1101, translated with Google Translate.
According to http://www.notebookcheck.net/NVIDIA-...M.22437.0.html the GT 330M should run at a speed that is higher than what is reported by CPU-Z:
Core Speed: 575 MHz vs my speed of 475 MHz
Shader Speed: 1265 MHz vs my speed of 1045 MHz
Memory Speed: 1066 MHz vs my speed of 680 MHz

I was curious if Apple has got its fan speed problem fixed for windows yet.
I know alot of people need their fans working good in windows for games and I would hate to have to boot into osx to set fan speed to high just so i could boot to windows to play a game.

I finally fixed all my problems (kinda) I have sound, wireless card, can go stadby hibernate, ethernet device works etc etc, Don't know how I did it because I went to so many different sites and google it thousand times!!!
I've noticed that sometimes you can't get the right drivers from dell even with the service tag number, I got some drivers from dell, but not from my specific model drivers download page!
The only problem I have now is that my hotkey: fn+esc don't work, it doesn't put my computer into standby like it should, the other hotkeys work just fine, Anyone know why? I also would like to get an older version of quickset because the new version that I got now I don't like it, its 7.1.8, I've been looking for the version that came with my computer from the factory but I don't know what version is! I liked that one better.

So about 3-4 weeks ago now I had to have my 7900GS replaced due to artifacting problems, and this ended up being a problem that was not fixed even after 3 repairs and replacements of the GPU itself, motherboard and screen, all got replaced about 3 or 4 times.
I rang up Dell for the 4th time, and asked to have a replacement but was told this was not possible until it gets to the stage where they need to take it in to the workshop. Anyway, the next day the technician came out and replaced the motherboard, GPU and screen again, and the problem was still there. I was sure that this would be fixed now, because they wanted to take it in to the workshop, which they did.
Now, I believe the problem has resurfaced, I was playing Crysis tonight and I had some more artifacting, the same type that I was getting before but, just in smaller areas instead of the whole screen. Here are some screenshots of the issue:
Screenshot 1
Screenshot 2
This has been happening on and off tonight, room temperature has been cool and I didn't notice any overheating.
Now I haven't noticed this within the last hour or so of playing, and goes away if I alt-tab then get back in game. The only other game I have been playing is Counter-Strike Source and I haven't noticed any artifacting in that, but that could be because it's nowhere near as graphically demanding.
I'm worried that the problem will keep coming back and possibly get worse, I have not overclocked nor plan to overclock and keep my machine in a very well ventilated area. This is not user error.
Using official Dell video drivers, was reformatted just week as well.
Do you think it's worth ringing Dell about this and try getting a replacement?

I'm about to buy one of these and Dell sales assistant told me that the original 1330 was shipped with incorrect BIOS settings and this caused problems..
He assures me that current laptops are shipped with updated setting and there won't be any problem. If there is they will replace the laptop.

I have an Inspiron 9300 that recently started having 100% CPU usage all of the time. After a lot of wild goose chases, the reason turns out to be that 3 out of 4 of its temperature sensors (CPU, Video, and soDimm) think that it is 255 degrees C inside the unit.
Error Code 3900-0626
Msg: Temperature Sensor out of range, temp=255C, min=10C, max=100C
As a result, the CPU steps down to preserve itself. I get perhaps 250MHz core speed rather than the 1.6 GHz the unit is rated for.
In any event, all other hardware diagnostics are fine, the machine runs ok (though very slow), and is otherwise healthy.
The Dell guys say that I need a new Motherboard, but I was wondering the following?
1) Whether the thermistors can be replaced by a shop that does motherboard repair
2) If getting an XPS Gen 2 mobo is worth a try. Would I still have to get new batteries, bios, etc if I planned to keep my existing graphics card? Can I do it without spending too much more money now that I would have to spend anyway on a stock mobo?

I recently returned my 1645 after 2 months of struggling with random crashing and throttling back to Dell for a full refund.
I am in need of a new system and was considering HP Envy 15 as an alternative, but I still like the 1645 given that it performs as advertised.

Over the past few months I noticed my laptop was super hot to touch and the fan was working overtime. I put this down to the additional memory and bluetooth device I installed 6 months ago.
The laptop began powering off without warning. It would just die.
I took out the memory and turned off the bluetooth and started disabling services I did not need in Windows XP.
This seemed to work for a short time. I noticed the fan going full speed whenever I used GFX intensive games. After power-off in the middle of a battle in Civ IV I decided enough.
Searched on-line and found some interesting notebook tools that reported the temperature of the CPU. Yep it was super hot. It appeared to be operating about 86oC. The system will power off once the CPU reach a critical threshold.
I figured the fan effectiveness must be reduced. I opened up the 5672 and took a look at the fan. Sure enough the dust was like looking into my vacuum cleaner.
I spent about an hour with a small screw driver, tweezers, some cotton swabs (q-tips) and alcohol based cleaner bulling balls of fluff out of the fan enclosure.
After I got all the clog out the CPU now operates a comfortable 55oC. No super fan blowing or sudden-power off.

beats edition as compared to the envy 15 version.
1. What reason is there for the 800 dollar difference in price other than the beats headphones?
2.Does the back of the case only have the beats logo on it or is there any type of laser etching like on the original envy.

I have a HP Envy dv7-7000 series laptop, C2N70UA, running Windows 8.1 and I'm having battery charging issues. It states it's plugged-in and charging. Yet after 4+ hours, the charge level is as it began (7%). I have updated all software; done a "System Diagnostic"; purchased a new battery; the charging adapter is good; BIOS does recognized the new battery and not the old battery. With the new battery and a diagnostic, the system displays following code:
"Failure ID: M0CCHL-6A478C-QFPK0K-C09C03
I am leaning toward purchasing a new motherboard and learn from "scratch" and understand what it may take to accomplish that feat . I am hoping it doesn't come to that.

I am running Windows 8.0 (64bit) and my wifi is not working properly on Battery mode. On AC Adapter, it works 100% perfect but in battery mode, it always goes to Limited Connectivity. Repaired it but 25seconds later it gets the same problem. Limited Connectivity every single time. It's an endless cycle. Warranty has expired and I am not happy with it.
Even if repaired, cannot open any website. Full 5 wifi bars but still the same result. Tried manually (TCP/IP Settings IPv4) but didnt work at all.
My wifi driver is Intel Centrino Wireless N 2230 ( 15.12.0.6 version updated from intel.com website).
Product number C2Y46AV (HP ENVY DV6 NOTEBOOK PC)
Tried everything that I could possibly think off such as disabling Norton Firewall & Running windows firewall but still the same problem.
Updated everything from HP.

On my HP Envy M4-1015dx laptop, I was editing a large image file in Photoshop, likely using a large amount of the scratch disk. In the background I had another Adobe program running though I had not engaged the application in the couple hours prior. Google Chrome web browser was also open in the background, with admittedly a lot of tabs open. So, the load on the computer/processor? was definitely heavy.
At this point, the battery died and the computer subsequently shut down. I plugged in a power source shortly after, and pressed the power button to turn the laptop on. The laptop booted and went to the welcome screen, I entered my password and the laptop got stuck on the "Welcome" screen that loads prior to opening to the desktop.
I pressed the power button to turn off the laptop and again to turn it on. At this point everything loaded extremely slowly. The screen where I enter the password moved extremely slow, taking at least 5 - 10 minutes to accept my keypresses and start loading the desktop.
Using any other application did not work, they became unresponsive. Attempting a system restore took over 30 minutes just to set a restore point and "prepare" the computer for a system restore. I was never able to complete a restore, I got an error during the preparation process.
It seems like the processor is just overloaded with even the smallest tasks now.
