Dell :: No Bluetooth 1645
Mar 28, 2010
All of the sudden, bluetooth stopped working on my laptop.
I installed the Dell driver when I first got the computer and everything was going fine. I was listening to music through some blue-tooth headphones this morning, when suddenly they unpaired.
Now, the BT light is on on the front of the computer, but the icon disappeared from the task bar. I tried reinstalling the driver, but got hung up when it asked to turn on blue-tooth with wireless button. The button doesn't do anything for turning on/off bluetooth that I can tell.
So now I'm stuck.
In Device Manager, there is no bluetooth 370 card. But I do have errors in the USB category and the "other devices" category.

Just got a new SSD, reinstalled 7, and can't find the BT driver.
The drivers from Dell.ca's site for 1645 says that there is "more than 1 disc, please insert all discs" () and 1640 says incompatible,

So my studioxps 1640 was replaced with a 1645. I was glad I got an i7 and a 1GB video card upgrade due to many other issues with the 1640, but I'm having a terrible time with the 1645.
First off, when I first used the 1645 for 15 minutes, the fan turned on full blast. I was just using firefox, so I ignored it and thought the laptop was just getting broken-in. But the heat issue appeared regularly. If I don't turn off the laptop, the whole laptop shuts down to either a bluescreen or it just powers off. Sometimes a weird clicking/crackling noise will come from the fan area near the heatsink even when the fan isn't on! It's like a bunch of metal balls are falling down a pipe.
I've left the bottom cover open to check if the heat sink was dissipating heat, but for some reason the metal area on top of the i7 was burning hot but the copper "pipes" were actually cool/cold. I'm getting a heat sink and fan replacement and I'll let you know how that works.
Next issue: webcam. On the 1640, running the webcam at 640x480 produced no lag and smooth pictures, but the 1645 constantly jitters at 640x480. Is this is a common issue?
Lastly, the bluetooth card is giving me a terrible time. I have used windows 7 x64 on the 1640 and bluetooth gave me no problems, but on the 1645 it is horrendous. I've switched bluetooth cards between the laptops so it's not a hardware issue. However, I'm trying to connect a bluetooth mouse and the card will detect a mouse, but it will never connect to it. I've tried numerous other techniques I saw on other threads. I ran the driver utility in compatibility mode, I've installed windows mobile device center, I've even formatted the hard drive. any help?

I've got a Studio XPS 1645 running Windows 7 (64-bit) and my bluetooth radio won't detect any devices. Everytime I start my computer I get an error that says "Unable to start the bluetooth stack service". I've uninstalled every bluetooth device I could find in my device manager and reinstalled with the latest drivers from the Dell website, but nothing has changed. I called Dell support and was told that the problem was related to software (for which I do not have support coverage) and that I should do a Google search for a Toshiba patch that might fix the problem, but I couldn't find anything online.

I bought at DELL OUTLET a M6400 without the Bluetooth Module, I will buy it separate from DELL, do you know if the Bluetooth antenas will be Pre-Wired in the notebook ?,
actually I am buying the DELL 410 Bluetooth + UWB card, meaning I need the Pre-Wiring for Bluetooth and UWB ?

I noticed a few other threads around the internet about this issue, but couldnt find a definitive answer on how to get it fixed, so I thought I would try it here.
The problem is that when I go into standby and wake from it, my bluetooth icon disappears and bluetooth doesnt work.
I have a Dell Studio XPS 13 running Vista 64 with the Dell bluetooth 370 minicard. Ive tried using the generic windows bluetooth drivers as well as Dell's drivers.
Nothing appears in device manager as well. I have to manually go into bluetooth settings, disable the device, then re-enable it.

My Bluetooth keyboard goes to sleep after a period of idle and it takes 15 seconds for the Acer Aspire 1810T to wake up and notice the Bluetooth keypresses.
However, I found out my Bluetooth keyboard works reliably when I have a second Bluetooth device connected and active at the time (such as either a headset or bluetooth tethering to a cellphone as modem), the computer doesn't have a 15 second lag in noticing the Bluetooth keyboard again - the keyboard works almost right away even after being unused for sometime.
So that means the culprit is in the power management on the Acer Bluetooth module. Is there a way to force the Bluetooth module to never go to sleep? Any checkbox somewhere, a register setting? Even going as far to purchase a different Bluetooth driver? Or any other option? Sometimes the sleep is useful, but it definitely isn't useful with the Bluetooth keyboard. This problem does not happen if I use an external Bluetooth dongle.
(With BatteryBar Pro, I notice that power consumption falls suddenly whenever the Bluetooth module goes to sleep when the keyboard goes idle for more than 30 seconds, and at this point, it has difficulty 'waking up' when I start typing on the Bluetooth keyboard. But the problem also still happens when the laptop is plugged in!)

I have finally tested the Acer Empowering Technology software on my Acer D150.
Great news, the software works to enable/disable the Bluetooth module on the netbook without physically pressing the button. This is great for people like me that do not have the button on top to push the button inside. There are two software needed for people to get this running on the D150. First is the required “Acer Empowering Framework” software and the second is the “Acer ePower Management.” Once both software are installed on the system, the setting to enable/disable the Bluetooth module is in the ePower Management.
Power profiles within windows will probably be reset to default, so those would have to be readjusted if a user changed them. I am actually running Windows Vista on my Acer D150 with the Acer Empowering Technology software for Vista. I am not 100% sure if the software will also work on XP, but from the notebookreview forums, I believe it should work just as fine (but more options on other Empowering Technology software).
(in XP, the driver also works, but need XP edition, not vista editon).

I have need to use Bluetooth stereo audio functionality (A2DP profile) almost exclusively when I use my laptop.
I had owned a M1330 with the Dell 355 Bluetooth Module for several years without issue. Last November, I decided to upgrade and purchased an M15x (laptop #1) with the Dell 370 Bluetooth module included,running Windows 7 x64 Ultimate. Not more than one day out of the box,the 370 module failed while watching a movie. It literally disappeared from device manager and no uninstalling/reinstallation of drivers alleviated the situation. The only way to get the radio to be recognized by the operating system was, and is, to shutdown,reboot into bios,disable the card in bios,reboot into windows,restart,boot into bios,enable the card and then reboot into Windows. The card would then work for awhile but eventually fail again. The module works for short periods of time but if put under an extended load,fails. That and other issues with the M15x caused me to return it.
Contacted Dell and returned the M15x and bought and built a Studio XPS 1645 (laptop #2) to replace it. Received the unit and literally within the 1st few hours,the 370 module failed exactly like the M15x.I thought o.k. a bad card and had tech support send out a new module for the XPS 1645. Received and installed it and the exact same problem happened. Failed when under an extended load. Again called tech support and was then dispatched an onsite tech to replace the entire motherboard and card. No resolution-card failed again. Spoke with a resolution specialist and returned it and again purchased a M15x (laptop #3-really liked the M15x over the XPS 1645)
Received the M15x-Bluetooth failure again. At this point, was considering dropping Dell altogether but thought I'd try the Studio 1558 (laptop #4) with the Bluetooth 365 module, in order to rule out the 370 card, first. Ordered and was delivered on the 5th of April, same exact issue-failure of card under a load. I am returning this defective Studio 1558 and again getting a M15x (laptop #5). I realize that the M15x Bluetooth card will fail again-in fact,am 100% sure it will fail,but have bought a Sony Bluetooth transmitter as a workaround.
What appears to be happening is that the card will shutdown when it gets warm.This is either a Broadcom manufacturing defect or a Dell engineering issue. I know now through personal experience that there is a serious issue with Dell Bluetooth cards.
If this was happening with only one laptop, I'd be ok with it but, this is occuring across multiple laptop platforms, with both Broadcom Bluetooth cards that Dell brands and sells.
This is either an oversight by engineering-maybe they didn't test the card under a heavy load, or Dell is knowingly selling defective equipment.

I'm currently deciding whether to buy the XPS 1645, 6GB RAM, i7, 500GB model of the XPS.
Or a refurbished MBP for the same price. (The one with 256MB DDR3 VRAM)
My main focus is video editing in HD. I've been using Windows 7 and OSX so am familiar with both systems.
What it comes down too right now is the build quality and the potential out of both machines.
I've read numerous reports of "Heat" problems from the XPS1645 which kinda scares me from buying it, however the 1080p and i7 kinda interest me.

I got the XPS 1645 with the Blu-ray Burner (in Europe). Does anybody know if this player is region-free?
And if not is there a firmware update or some type of way to make it region free so that I can play region A (US) discs too?

I have just received my new Studio XPS 1645 yesterday. since then i had been trying to install XP OS. then finally after being touched with dell, they said me that this machin is not compatible with XP Operating system. anyway, after that i tried to install vista ultimate and win7 dual boot. finally today i made it.
but the problem is both in VISTA and WINDOWS 7 the default font and icon is very small. in vista the taskbar icon is so small that they can hardly be seen. my screen is 15.6" widescreen with full hd (1920X1080). I have changed DPI Scalling to 120 DPI from the Default 96 DPI. but still the task bar icon (show desktop, switch between windows,internet explorer, mozilla firefox) is small. i have installed mozilla and it's font size has also become very small but clear(it seems). i m wondering is it they way in high resulation machine should appear. it's annoying. plz help me guys who is having this laptop.

I ordered my XPS 16 during the signature event on 1/18 and it has a ship date of 2/8 which is on Monday. I don't expect that my laptop on time since its already Friday. The online status still shows it as pre-production and the two numbers I called say being processed/pre-prod/building plus the chat is no different.
I really hope there is no delay. I want my laptop
Anyway just wanted to post and say hi.

I generally use my computer each day, and if I close the lid at night without shutting the computer off, in the morning the computer will be off.
That wouldn't be a bad thing except many times it'll shut the computer off so I lose everything that was opened up. But the only weird thing is that it won't happen every time.
I was just wondering if any of you have this problem and if there was some setting that I overlooked each time when I looked to change that. It's not a big thing, but I had a Dell computer provided by school and it would still be on in the morning after using it at night...........................

I'm going to be sending back my sxps 1645 to dell. It seems like this whole model is buggy and I don't feel like paying good money to be their beta tester. So I'm wondering what the best way to wipe my solid state drive is.
What is the best way to ensure private data is completely gone on an SSD before it goes back?

it seems that my lovlely 1645 keeps on freezing completely in random fashion. I have not noticed any patterns as everytime it has frozen it has been while doing something different, such as surfing the web, plugging in peripherals, etc etc. So know ive HAD IT. First with the bsod's when fullscreening a flash based video online, which i attribute to the video drivers, of which i have tried installing MULTIPLE, with no solution, and happens to begin with the screen freezing, and now the stupid freezing caused by random events..
Do these issues affect anyone else? I have noticed that the random freezing started to occur after flashing to the A03 BIOS.
i have already reinstalled the OS once, and dont want to do it again....unless absolutly necessary.

I'm under the impression that the Studio XPS 1645 will be using a similar, if not identical, chassis to the 1640. Given that, how easy is it to replace the hard drive with a SSD?
I didn't bother with a SSD option on account of the price, but once the price comes down a bit I'm hoping to replace the drive and use the existing drive externally.
How much of a headache is this and what should I be aware of with regard to known SSD issues,

Is anyone else experiencing real high fan noise while playing a game? Even with the sound on it's clearly hearable and really annoying and continues going.
As soon as I exit the game it's over, so it probably involves temp & CPU clock. My temps are about ~70C when I exit

Less than a month after receiving my 3rd replacement system from dell, I experienced strange problem... I couldn't adjust the screen brightness anymore, altought the quickset was showing movement, the brightness was constantly at max. So I get into dell tech support chat, explain the problem and the guy send me a link to a program that would grand him access to my machine.
He login and start installing some drivers... chipset and etc. He try to flash my bios but i stop him even before downloading it and told him that he will not do that on my laptop. Then he said that he needs to restart the system and this should fix everything. I said ok .....

Is it worth the money to go for the 128gb SSD?
Is it better to get the cheapest hard drive and replace it with your own SSD?

After a development version of the BIOS for the Studio XPS 1645 turned up, some people were concerned about reverting back to an older BIOS after flashing the X29 version. To solve this problem I extracted the WinPhlash utility from Dell's BIOS package and modified the settings.
Now you have several options:
- Simply backup your existing BIUOS
- Upgrade to any version you like
- Downgrade to any version you like
I compiled a package that contains the following BIOS versions:
A01, A02, A03, X29 and A05, A07, A08
This is as far as I know the order in which they were released. The X29 version was never officially released.
Just to be clear: I did not change anything to the actual BIOS files, just to the WinPhlash program settings. These are original, untouched Dell BIOS files, and the same program Dell uses to force-flash your laptop. I just changed a few settings (allowing us a choice of options).
Disclaimer:
I cannot and will not assume responibility of somehow your laptop is bricked during the flashing process. This can happen with Dells own updat packages as well. I myself have used the tool in my package, and others have too, with success. This is however no guarantee for succes.
Please also note that I do not have either a 1647 or a 1340, so I cannot test these files. The theory behind updating the BIOS is the same for all these machines, and the 1340 packages appear to use the same WinPlash64 tool.
The packages can be found here:
20100327_Dell_Studio_XPS_Bios_Tools.zip This package contains the flash tools and the crisis recovery bits.
I have put the different BIOSes in their own packages:
20100327_SXPS_1645_BIOS.zip contains the BIOS files for the 1645, including the latest A08.
20100327_SXPS_1647_BIOS.zip contains the BIOS files for the 1647, including the latest A05.
20100327_SXPS_1340_BIOS.zip contains the BIOS files for the 1340, including the latest A11. The BIOS files for the 1340 seem to be smaller (about 2Mb vs 5Mb) than the 1645/1647 files.
UPDATE: I added the A06 version to the package. Also included Andrew's crisis recovery kit (see this thread for details). I have moved the package to my own server.
UPDATE: A07 is now also included
UPDATE: A08 is now included, and added packages for 1647 and 1340.

I have spent two plus days searching thread after thread and I am not getting anywhere! If someone could point me in the right direction I would appreciate it. I just got my 1645 yesterday and what I want to do is to remove the hard drive and put it into my desktop and create an image. I will be formatting the drive removing all three partitions and install another OS. Later on down the road I want to be able to reimage my drive with the original backup. I do not want to clone the drive as I will be using it... I have tried Drive Image and it successfully makes a backup image and when I use it to image another drive the 'OS' & 'Recovery' partitions are fine, and the computer even boots into Windows. But when I use F8 to access the repair console I get a '0xc000000e' error. All of the information I find is somewhat outdated and refers to the period when Dell used Mediadirect.

recently got a replacement for my laptop with an xps 1645. However when it got here I was having a hard time viewing the screen with the wide screen view. My current laptop has a
15.6 945p HD+ WLED LCD
However I have an option to get either a
16" FHD RGB Display in Merlot Red with leather and 2.0 MP Webcam, 1645/1647
or
15.6 FHD WLED Display in Merlot Red with leather and 2.0 MP Webcam, 1645/1647
I'd prefer to have a more normal screen size. Can anyone tell me what is the difference between these three monitors.
