Dell :: Studio 1749 Fan Noise/temperature Problems

Feb 13, 2010

I've recently received my dell studio 1749 laptop with the following specs,

- i5 CPU 520m

- 4 gigs of RAM

- Intel HD graphics

- 320 gig HD

The problem with this laptop is that the fan will start to whine every few minutes seemly without reason.

I've done some investigation and found out the following:

- there seems be a threshold of 35 to 36 degrees celsius. Once the CPU hits that temperature, the fan will start to cool it down to under 30 degrees

- the idle temperature of the CPU is always creeping up, even without load. If I leave the computer alone at idle with almost no CPU activity, the temperature will creep up to the threshold...thus triggering fan.

the cycle repeats itself every few minutes.

I've attached a picture to illustrate the problem.

Since this is my first laptop, I want to ask does the CPU temperature stay constant during idle? or does it creep up like mine?

Can the threshold be modified?

Is this normal with the dell studio?

Dell :: Studio 1749?

Jan 25, 2010

I believe '1749' is the model number for the core i5 Studio 17 - anyone know when it will be released or whether the i5-540m will be available? Considering buying an XPS 1647 now but would prefer the 17" screen

Dell :: Studio 1747 Vs. 1749

May 4, 2010

This is for the Dell USA site as of 5/6/2010....any other countries and/or times YMMV

There are some notable differences between the 1747 and 1749 being offered via the Dell Studio 17 selector

1749:

ATI 5650
i3-350M, i5-430M, i5-520M (No i5-540M or i7-620M. No Quad Core Options)
1066 memory (Makes sense since dual core i3,i5,i7's only support up to 1066 memory)
9-Cell battery as default option
1yr Warranty default
1080P "RGBLED" panel Description/Product Code = DH1080F / 320-8968

1747:

ATI 4650
i7-720QM, i7-820QM (No dual core options at all)
1333 memory support
9-Cell battery as default option
2-yr warranty default (No 1 yr option)
1080P "B+RG" panel Description/Product Code = CH1080F / 313-8043

Blue Ray RW drives are now an option for both @ $150.00
Intel 6200/6250 options are available for both

I'm definitely curious about the panel changes along with system board revisions to see if the 1749 supports Quad Core CPUs.

Dell :: Pulled The Trigger On A Studio 1749

Mar 5, 2010

As the title says i bit the bullet and ordered a 1749

Spec
i5 520m
4gb ram
1TB hd
Ati 5650

All for the paltry sum of £673.
This is the first lappy i have ever bought and i have done so to make space by getting rid of my ageing desktop.
Problem is i am now on the verge of buyers remorse so i am asking for a little input on my choice. I would really like the input of you guys who have been around Laptops for a while.

Dell Studio 1749 :: RAID Controller Or Not?

Apr 18, 2013

I have a Dell 1749 into which I have installed two OCZ Vertex 3 MaxIOPS SSD drives.  Boot times are pretty fast using a single, non-raid, drive but I was thinking of configuring the two drives in a RAID 0 configuration to boost speed a bit further.  I could not find anything in the bios settings that would allow the SATA controller to go to a RAID configuration.  I guess, therefore, that at least the laptop that I have does not have RAID capabilities.  Were there any Studio 1749 system boards that did indeed support RAID?

Dell Studio 1749 :: 3 Blinking Lights But Will Not Power On

Aug 12, 2014

My daughter's 1749 laptop shut itself off and now when you plugin the power adapter, the light over the plug on the laptop blinks three times.  It will not power on at all.

I have replaced the power jack in the laptop as well as the cpu and tried different known-good ram but nothing makes any difference. What does the light over the power jack blinking three times indicate?

Dell Studio 1749 :: Extended Battery Life Gone

Jan 6, 2012

I had to reset my Studio 1749 to factory defaults and now the option for "Dell Extended Battery Life" within the Dell Battery Meter is gone. I don't know what needs to be reinstalled in order to get it back.

These are the changes that might affect the issue:

- Installed a different WiFi-Card (Dell 1520)- Installed a different Tuner Card (Yuan, provided by Dell)- Installed Service Pack 1 for Windows 7- Flashed BIOS to A08- Updated all Drivers and Utilities from the Dell Homepage except for the ATI-Driver

I think it is a useful tool if you use your notebook on battery, because it is able to control a few options that are not available in Windows 7 default power plans.

Dell :: Studio 1745, 1747, 1749 Backlit Keyboard Aftermarket?

Apr 20, 2010

I just bought a Studio 1749 with a Dutch US international keyboard. The US backlit keyboard is the only backlit one and not an option here.
The only difference is the missing Ä symbol at key number 5, for which I don't care so much.

Now I'm trying to find the US backlit keyboard at eBay or Amazon without success. Is there a way to find one aftermarket and get it shipped to Europe?

Dell Studio 1749 :: Shuts Down Randomly Without Warning And Then Won't Start Back Up

Oct 19, 2011

I'll be using the computer and all of the sudden it turns off, it doesn't log off or say it's shutting down, I mean it literally loses all power. Then I try to restart the computer and you can hear the machine start to come on but then it dies again. I've tried charging it, I took the battery out and put it back in, etc. I'm just not sure what the problem is. I've only had the laptop for 1 year and 3 months and a few weeks before the year warranty expired the computer started to say that the battery life was coming to an end and so Dell had to send me a replacement battery. I've tried leaving the computer alone for days at a time and still nothing and of course it's no longer under warranty so I can't even call Dell without getting charged.

Dell Studio 1749 :: Stop Charging - Laptop Won't Power Up With Battery Removed

Mar 8, 2010

Last Friday i received my new Studio 1749 with i3. As told by the documentation I put in the battery, put the power cable in the ac-adapter, pluged the AC-cable into the laptop and then pluged the ac-adapter into the wall outlet. I booted the laptop and once I was on the windows desktop had a look at the battery symbol. It showed that the laptop was connected to external power and that the battery was being charged.

I wen't away from the laptop to let it charge the battery for 12 hours as told by the documentation. After two hours i came back to have a look at the laptop and it was off. Curious I turned it on again. After booting up it showed the battery at 60% and the laptop running from battery. Yet the ac-adapter was connected to the laptop. I hadn't changed anything. I pluged the adapter cable in and out, but it wouldn't recognize that the was external power available. Turning the laptop off an on again didn't work either.

Now I feared for the battery. My guess is that at one point it started to run on battery power even though it was not charged for 12 hours. Then when the battery was depleted the laptop shut down. This might have permanently damaged the battery!

I guess as soon as the laptop was off the ac-adapter charged the battery again, and when I came in it was just at 60%.

So I turned it off removed the ac-adapter, removed the battery, put the battery back into the laptop pluged the ac-adapter back in and booted up again. Now it showed it was running from external power again. All fine. It charged the battery as well. Actually it charged the battery up to 99% and then out of nowhere the battery symbol changed and it was running from battery AGAIN! Even though it was still connected to the ac-adapter. This happens all the time. It is reproducable.

So I thought something might be wrong with the ac-adapter.

I powered down the laptop and removed the battery. Now with only the ac-adapter connected ,I tried to start the laptop. The control lights above the keyboard came on for 2 or 3 seconds and then the laptop turned off again. Trying to hit the power button again after that didn't give another reaction.

Conclusion: The laptop won't run just on external power with no battery in the battery bay.

I put in the battery again. AC-adapter still connected. Hit power. Laptop starts to boot. Then while booting I removed the battery. Laptop keeps on booting - finishes booting - runs nice and well at full speed not missing the battery - FOREVER.

So it won't boot with the battery removed, but it will run without it flawlessly??? Strange isn't it?

Next test: I put in the battery again while the laptop is running from mains. And now it charges the battery again until the point... you already know... it "forgets" that it is connected to the ac-adapter and starts running on battery power. So now I boldly removed the battery while the laptop was running. After all it was still connected to mains/ac-power.

Dell Studio 1749 :: Power Adapter Is Plugged Into power Board Along Side Of Laptop

Jan 27, 2013

Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.

Dell :: Fan Noise On Studio 15

Nov 29, 2008

I just got a Dell Studio 15 from the Dell outlet and while it's a great laptop I am wondering about the fan. It runs constantly and you can definitely hear it the whole time.

When I opened the media player it revved up a little but I wasn't even playing a video. Is this fan noise and constantly running fan normal for the Dell Studio 15?

I love the laptop but I think it is louder than usual and find it odd that the fan runs all the time. The bios installed is A05.

I have the model with an ATI video card if that makes any difference.

Dell :: Fan Noise On Studio 1558

Dell :: Studio 14Z Fan Noise Driving Me NUTS!

Mar 27, 2010

I thought this would not be such a big deal when I bought it, but I was wrong. i8kfangui does not work, I turn power to 'power saver", but even then fans go full speed. It does occasionally slow down or off, but seems completely random. Right now I see core temps at 35 and 37, with fans at full speed.

Dell :: Optical Drive Noise In Studio 1558?

Feb 6, 2010

I got my Studio 15 notebook yesterday.

Whenever I power on my notebook. I hear one sound twice for a second. There after on 'Dell' screen I hear it once again just before Windows 7 startup screen appears. I think it's from slot optical drive.
Am I correct?

I have never used a notebook before.

So kindly tell me is this normal ? Do optical drives in notebooks make such sounds at startup as well as more noise while using (compared to desktops)

Dell :: Static/white Noise On Earphones (Studio XPS 1640)

Feb 19, 2009

I hear white noise / static noise (whatever is the proper term for that) when using headphones with Studio XPS 1640. It is most audible when no sound or music is being played from the laptop.

I'm not if it has something to do with the type of headphones that I am using (I have two sets of Creative earphones that I got together with my XPS M1210 and 1530).

Dell Studio 1558 :: Power Brick Buzz / Sizzling Noise

Dec 8, 2012

I have a Dell Studio 1558 and I have some concern about my power brick.  The brick itself makes a light sizzling, buzzing or light crunchy noise which isn't continuous, but is causing me concern.  The computer itself, also makes a similar noise when doing stuff like scrolling down a page in an internet browser.  Every time I press the down arrow and it loads new images, it makes a brief sizzling noise.

When my computer was brand new I brought this up with tech-support and they gave me a new power brick but the noise never went away.  I took a day off work to stay at home and waited for a tech to come to my house so I haven't complained about it since then.  It seems to be an intermittent issue, some days its worse than others, and I've had this computer for about 2-3 years now.

Have there been any recalls on the power supplies for my computer? Aside from making a noise, I haven't noticed any decline in my computers performance, I'm just worried about it shocking me or frying some of the components inside the computer!

Dell :: Warning About A04 Bios Update For 1749

May 7, 2010

I have a dell 1749 with I7 and the ATI graphics card and loved it till today when I applied the recommended A04 version bios update.
It stopped at 69 out of 70 in the install process for over an hour and then I had a brick!

Dell have agreed to replace the unit as it is less than a month old and totally fried, it wont even get to the dell logo stage which means you can't revert to the previous bios.

It may have been that it was already faulty but I would be very wary of updating the bios at this time.

Dell :: Getting A Studio Slim/Vostro 220 Slim How Is The Noise Level?

Apr 12, 2009

I plan to get a Dell Studio Slim/Vostro 220 Slim. At first I wanted a Dell Studio Hybrid, but since I am using this computer for streaming live TV I can't add in a tv tuner to that and is out of the race.

Therefore the Studio Slim/Vostro 220 seem like the best small dell computer that I can use as a media center PC (streaming movies, pictures, live TV all from WMC/tv tuner). Does anyone know how is the noise level is? Can it be heard? Watching movies? Fan noise?

The noise of the system is a deal breaker/deal maker for me so the more detail anyone can give the better
