Kindly check if the new Macbook Pro's throttle their CPU's under loads when plugged in...?
I am considering to buy Macbook Pro 15 with i7 and standard screen ( high res not available in India__ 17 inch model does not come with i7 here)...
Do the studio 15 throttle?

View 4 Replies View RelatedI've been using my nx7400 for more than 3 years. I undervolted it with RM Clock and it was always running around 45-52 degrees idle and 53-59 under load. The fan only kicked in under load and over 55 degrees.
I changed the CPU fan for a new one, I changed the thermal paste for MX-3 and I regularly use compressed air to clean the heat sink.
Lately, it's running full throttle in intervals even in idle and temperatures 45-50. (5-15 seconds full throttle, 10 seconds inaudible... and so on)
I could always leave it on my nightstand 24/7 as it was inaudible.
This thread is getting too large, and too difficult to find useful information. Thank you to everyone who has put forth efforts into the investigation. At this time I feel we can safely say that there isn't any investigating left to do, so without further ado, please direct yourselves to this great help-thread with information about what the problem is, and how you can circumvent it:
S-XPS 1645 Throttling Info. and Updates
====obsolete information====
I've removed all the old information as its mostly speculative, and replaced it with useful factual information.
The following is from a post made by our user Khaledseif on the Dell Forum. I feel this update he posted is so well-written that it deserves to be included here.

1. The power conservative BIOS forces the system to throttle to 7x when the power consumption is around 90 watts due to one or more of the following reasons:
a. Limitation of the power supply capability
b. Limitation of the motherboard to accept more than 90 watts (This reason is from DELL, but we suspect it)
c. To increase the battery life
d. To limit heat generation
obviously DELL should be blamed for poor design if it is a, b, or d.
2. Thanks to unclewebb there is a software now to unlock the throttle, this one will almost certainly put the 90 watt charger to rest or fire.
3. Due to the power limitation, it looks like the people with the RGBLED are most affected by the problem due to the added power consumption.
4. DELL is aware of the problem, but according to them it only affects a small percentage of people that put the system on full performance.
5. DELL keeps saying that the 130 watts adapter is not the solution of the problem, which is quite true as it needs both an adapter and BIOS update.
6. After a long wait, DELL acknowledged that there is a problem and that they will address it soon without announcing a time frame.
7. We as a group lack the trust in DELL fixing the problem to our satisfaction.
I think most of our group will agree on the above.
With all the above said, i am quite happy that mine was returned back to DELL after a frustrating experience with DELL level 1, 2, and 3 technical support. This doesn't represent the other members as most of them are happy with their notebook but expect action from DELL.
I have sent an e-mail to Acer but, as I bought my laptop in Dixons (UK retail shop) they told me that I need to speak to the "Tech Guys". These "tech Guys" are.... well...
THICK as S*** and don't usually give you any help whatsoever. Their advice was something like... it is not our fault, contact Microsoft as they are the one who developed W7...?
Anyway, moving forward, my problem is that, since I installed W7 x64 (clean install) the volume throttle does not work. I am unsure what the driver for this function is. I have tried re-installing the Synaptics drive, the Realteck HD drive...
I have my MBP set to put the screen to sleep after 5 mins of inactivity and system to sleep after 10 mins.
This works fine when not plugged in, but when connected to the power the screen goes to sleep but not the computer.
I am not running any apps in the background except Quicksilver...
I dont have my Time Capsule just yet, and am looking to set up Time Machine to an external USB HDD.
If I dont have the external drive plugged in, does it just skip the scheduled backup its missed?
Can I just create the initial full backup, then stop the scheduled backups - so only have it incrementally backup when I manually run it?
I got my M1730 in April this year, with the Raid 0 array, 2X160Gb drives, 2X 8800GTX, the physX card, and the 1900X200 display. (and if it matters, the Ivory White colour scheme).
I love the laptop to bits - it was bought to replace a loud, space-filling, 2xdisplay main rig, and it's done that brilliantly.....
...... when it hasn't been crashing.
I've had periods when the M1730 hasn't booted into windows for hours. BSODs all over the place, during windows (vista 32) boot, during windows use. With a Wide variety of crash 'reasons' -
IRQ_NOT_LESS_OR_EQUAL
MEMORY MANAGEMENT,
TCPIP.SYS..
...and a few others that I didn't have a chance to note..
My instinct is to think that it's my mis-management of the new system - I don't particularly like vista, but it uses all the ram i've paid for, and that's good.
But it's crossed my mind that it could be an overheating issue; and it arbitrarily picks a component, or driver to blame.
It actually gave me a RAID0 failure last week - I performed a disck consistency check, and it was all fine..
I have a dv1000t HP Pavilion with XP home edition.
I have been trying to download Windows compatibility pak so Office 2003 can read office 2007 documents.
I had no problems download it on my z70va ASUS. It downloaded in just a few minutes.
But on the HP -- the download is taking over an hour.
When this first happened, I though there was some malware on it. I run AVG Internet security all the time. But just to be on the safe side I downloaded Spybot Search and Destroy and checked with that -- nothing (though I did have it delete all my temporary files, Super AntiSPyware, nothing, Malwarebytes AntiMalware -- it found one registry infection Hijack.start. From what I read elsewhere that's a false positive but I deleted it anyway.
I also installed SP3 on the HP a few days before all this.
My internet is a high speed DSL and both the HP and the ASUS are on it. SO I don't think that is the explanation.
It seems a little bit like even IE is loading slightly slow -- but I am not sure if that is my imagination.
I installed ubuntu on my laptop through a flash drive. I then loaded up Super Grub from a CD to remove ubuntu and grub to restore Windows boot menu because I preferred XP, I followed the instructions from Super Grub menu, and I was sent directly to the Acer erecovery. I decided to restart my laptop after that, reset everything in the bios, including boot order, but now my laptop keeps booting up acer erecovery, even after going through the process.

On start up as soon as you first press the power button, there is no display no life at all on the laptop's screen. No POST screen or Windows loading screen. Now after windows have loaded the display appears back on the laptop.
If i hooked up an external monitor and do a cold start i can see everything working the way it should on the external monitor and then as the windows have finished loaded the
image switches back to the laptop screen.
It seems like the bios is using the vga out as the primary video until widows drivers have take over and switch back to the laptops screen. The same happens when the external monitor is hooked up and when it isn't.
There is no option in the bios to change the default screen.
I tried everything i could think of.
FN+F5 key dose nothing until windows have loaded
CTRL + ALT + F1 or F3 (alternative keys for changing the display)
Did a full system recovery(format and reinstalled windows)
Flashed and updated the Bios, From 1.25 to 1.27
removed and reinstalled ram, battery, to draining complete power from the laptop.
2 display drivers show up. I tried removing and disabling them one at a time.
Still no change.
No power, no lights, no display, no nothing on the laptops screen until windows have loaded. After windows have loaded everything works perfect, except when resuming from hibernation, the screen that says resuming from hibernation do not display because the bios is using the vga out as the mains.
After a few seconds the screen lights up and continues to resume as it should.
The netbook has not been dropped one or had any damage what so ever.
Acer Aspire 9504.
First of all it runs in Windows completely rock solid. I have ran stress utilities for over 24 hours, and the system is completely stable.
My problem is that it is very unstable before windows loads. For example, if I simply leave it in the BIOS setup for 5 minutes the computer will just power off. It is also quite hot underneath. This occurs also if I boot from DOS (or other e.g. XP recovery disk) boot disk to run some utilities - the system will run for 5 minutes or so, and then just power off. The time that I get before it powers off decreases if I immediately switch it on again, suggesting an overheating issue. I did not have this problem when I first got the laptop 3 years ago.
This problem is really annoying as I want to run some low-level utilities to repartition my hard disk and also possibly reinstall windows, but this problem is preventing that.
Any ideas? Perhaps some strange software that I installed? ACPI config? Memory issue? BIOS issue? Computer is hot in several areas under where the CPU / TV tuner / graphics / memory are located .
My system spec:
- Pentium M 760 2GHz
- Ati X700 256MB graphics
- 2GB crucial RAM (2 x 1 GB DDR2 533 CL4) (upgraded from 1GB over a year ago and fully tested to be working)
- Newest BIOS from Acer installed

View 5 Replies View RelatedI have a Dell Inspiron 1545 and have had this laptop for 3 or more years. Last night I shut off my laptop normally but today, upon booting, the screen just turns black and nothing else.When starting up, the Dell logo still loads and the screen still shows "safe mode or start up regularly."
Upon choosing either option, the screen loads for awhile then fades into black. Nothing else happens after.I would atleast like to know how to save my files within the laptop. [Atleast to start it up once more to save all the files to a USB and not lose them forever..]
My touchpad works with the recommended Dell Alps Touchpad driver installed. It seems clear that this driver (apoint.exe) is only required for gesture control of the Touchpad, and this is my problem.
I start my laptop (Windows 7 Pro 64 bit) and use auto login. The laptop is quickly ready to use. I open firefox or other programs, but I can't scroll with the touchpad. The apoint.exe hasn't started faster than I have, and the gesture controls are not recognised when I use them. When I wait a few seconds, the driver is then active, and the gesture controls work.
This is highly annoying ! I don't have many programs running at start up (I've just done a clean Windows 7 install). My anti virus software does take some time to come up, but its not excessive.
How can I increase the priority of the touchpad driver apoint.exe which I can see in msconfig ? It needs to be up and running fast.
Is it possible to somehow set a group policy in Windows 7, so that this program is running before login is allowed ?
I've tried the recommended Dell driver, and also tried a later version which I found via searching on the Dell web site. Both drivers work fine, but they both take too long to load.
When I strart my laptop it will show the Acer screen with the F2 F12 options then goes black with cursor in upper left corner and when windows should load it goes back to acer screen and will keep doing this till I smack it on the side then it will load windows and run normally. I created a disk image, bought a ner hard drive, loaded my image onto the new hard drive and it worked fine for a couple hours of starting and shutting down. Then it started doing it again ...

And if I press power button, its turning off. Later I've pressed F8 key to login in Wiindows Normal Mode, its opening Windows. So every time i've to press F8 key to login. Sometimes the beep sound continues and not logging in normal mode or in Safe mode.
I thought it might be RAM issue and I checked 'System Settings' in Control Panel, it shows the usable RAM is 2.77GB of 8GB.
I went to Dell laptop service center near by my location and they said its keyboard problem, they charging too much amount to replace keyboard. but my keyboard is working properly.
I have a training environment using W530 laptops that are enclosed in an area in front of the desks. It is not pratical to get to the computer as it is hidden away and therefore I need to be able to use the dvi cabled external monitor for bios setup, boot order, etc.
Right now the boot options are hidden from the external monitor until windows loads. Then the external monitor becomes active. Any way to bypass the laptop monitor altogether?
I inadvertently upgraded to Windows 8.1 which I had been trying to avoid doing and don't know how it happened as I had continually knocked back prompts to upgrade. I originally did upgrade to 8.1 last year and had such major graphics issues I eventually restored factory settings to get back to Windows 8 which solved all the issues. Now the same problems are happening i.e. breaking up of the screen with loads of horizontal lines running across it.
I downloaded all the updated drivers I could from the Dell site but the graphics driver and video driver would not work and I kept getting the message that the laptop was not compatible with the downloads. It is a Dell Inspiron 3520 and the recommended drivers just will not install. I don't want to have to go through all the hassle of restoring factory settings again. I am sure the problem is with these 2 drivers mainly the NDJN4 video driver.
my laptop vostro 3460 won't boot any more. When I turn it on it loads the Dell logo (I suppose it passes the POST) but then it just shows a black page. It could be anything, but I guess that it may have something to do with Windows 8 and the UEFI system. I also would be quite happy to install linux mint and get rid of Windows, but I don't know how to change the boot priority order.
So my questions are:
1 is it a hardware issue ? if not, can I solve my problem easily ?
2 how can I change the boot priority order, to install mint ?
When I first loaded up my Vaio the Startup Assistant booted by itself and I unchecked the box to stop booting on startup. After the while the Startup Assistant started booting up by itself even though the box is still unchecked. I thought by recovering to factory settings and unchecking the box would fix it but it has started booting up again.
how I can get rid of the Vaio software?
I recently got the dreaded "Plugged in, not charging" message in vista of my Dell XPS 1530.My laptop is out of warranty .I tried all the methods suggested and flashed the bios to A09 from A12.I also checked the BIOS and it says
Battery Charge = 6%
Charger = 90W
Also when I connect the charger the charging light would flash for 5 sec. and then go off.Due to this the battery charge has moved from 6% to 7%.
I cannot buy a new mbd worth $500 . Any other cure for this ????
I own a dv5t. I am just noticing this now.
My battery will not charge. It says plugged in, not charging. The light by the plug in is lit up. I never had this problem before.
My Dell XPS 13 Ultrabook is plugged in but will not charge. The battery is completely drained and the power will immediately shut off when the power cable is unplugged. The battery meter indicates "O% Available (plugged in, not charging)". Every time I restart it I am told to plug in a Dell charger with 45 watts or greater. Thinking my charger might have been the issue, I just purchased a Dell replacement charger, and it is still not recognizing it. I have seen on other posts that indicate a possible solution is to update the BIOS; however, when I download and try to run the latest BIOS, I am told that the battery needs to be at least 10% charged in order to update.

'The AC power adapter type cannot be determined.
Your system will operate slower and battery will not charge.
This problem might be solved by:
Ensure the plug is inserted completely for best system operation. Connect a Dell 130W adapter or higher'
i've always taken really good care of my laptop never dropped it or anything i hope that its not broke...
if it is broken and i have my year warranty do i still pay for whatever new part i need?
