Dell :: Anyone Ever Get A Faulty Thermostat On Their Mobo?
Jan 19, 2009
Well dell came out and once again replaced the mobo today... making this the 3rd time this computer needed servicing... and to my surprise while test driving it today (after the guy left), the computer shut down after reaching over 100c on the ACPI temps...
funny thing is, i didnt smell anything burn, there was no heat at all, and everything seemed fine...
i unseated the heatsink and tried it again, sure enouh the same thing happened. the fan maxes out as soon as i start the PC, when it loads windows...
then once i get there, it completely stops... i mean the fan blade arent turning .....

I posted a thread earlier about my CPU getting very hot. Nobody said it was to hot for gaming but my CPU is downclocking when I play a game longer then 5minutes. I have it proped up, my fans on on high, and cleaned my vents and it's still hitting 85C in as little as 30minutes of gaming. My 80NM 360 don't get near this hot. My last laptop (M170) only got to 50C.
So my question is:
is my CPU faulty or does anybody know how to fix this? Hell, it's 60C right now!

I'm thinking of modding my i9300 to accept a 1710 mobo-- if I buy a motherboard with integrated graphics, will I be able to add a graphics card later on and disable the integrated graphics through bios, or does integrated graphics preclude adding a card later on?

I think my xps9300gen2 might have some major promblems.
My battery went bad........got the bad battery flash code and the battery lights on back would light up funky.
I bought a new battery and the light isn't flashing anymore, system recognizes and charges it, BUT when I unplug the AC power to run on battery I get artifacts then system freeezes. I tried a third battery but it's the same deal. Won't run on the batteries
I fear it's the mobo.
Anyone delt with something like this?

I have the Dell XPS M1530 laptop, and of course the motherboard is fried.
The laptop is no longer covered by warranty, and I dont want to buy a new mobo from Dell, because they charge a ridiculous amount of money.
Where can I buy a new mobo with the new non-faulty Nvidia chip? I don't want to buy one of the original ones because it will just overheat from the chip and burn up again.

my recent purchase of an xps1530 i have noticed that my graphics in my game have not run as well
when i play counterstrike source it will be like 100 fps for like 5 mins then all of a sudden it drops to 20 fps. its horrendous to play
other games run terrible like world of warcraft and mass effect. is there any fix for this
is this a heat issue?
can i set my fan higher
if its faulty how do i get a new card?

My M1330 has developed the "ac adapter type unrecognised" problem which means a new mobo. But it may be. It's an early m1330 with the 633MHz FSB and 2.2GHz cpu.
Do you think Dell will be able to replace like with like? I'm rather hoping they'll give me a 2.4GHz with 800MHz FSB as replacement as that's the nearest CPU match without giving me something inferior.

so my i6400 came orig with 2x512 ram sticks, one per slot -- recently (i have it it 2+ years) i realized that i was having a RAM issue (BSOD + other windows errors pointed directly to this problem) and ordered 2 x 1 gig sticks of ram from
newegg...when i realized what the problem was i pulled out 1 of the 512 sticks and it worked fine -- without a problem
i recieved the 2 new sticks and put them in, tried to start up, no luck...
tried one stick, worked fine.
(turned off)
tried other new stick, worked fine
(turned off)
replaced the original stick, worked fine.
(turned off)
replaced orig stick #1 with the stick that i thought had died/was bad, worked.
(also dealt with the dell POST? diagnostics -- flashing lock indicators -- which told me there was a problem with the RAM).....

what i wanted wass to fix/bypass the sensor without having to replace the damn board. i couldn't even find a single post staing where exactly the sensor is on the board.
my problem specifically was that beer got spilled on the keyboard. after a while the machine shorted and shut off. I have a Dell Inspiron 9300, with a 1.73 ghz Sonoma CPU. i left the laptop off for two days so some of the liquid would dry out. after some problems and a dozen reboots i got into the bios, then finally through to windows. everything was fine except that the CPU was working at a very low frequency. also the fans were continually at highest speed. the CPU was being reported between 101 mhz to 503 mhz, depending on the software. it was being recognized correctly but showing to operate at 202 mhz in the system properties panel. what was really striking is that the notebook harware software i had installed was reporting the CPU temperature as 85 C. I tried various software to manipulate the CPU frequency to no avail. The temp was a constant 85 C, although i could tell that it was not even close to this temperature since i my laptop was partly disassembled and i could feel the surface of the heatsink with my hand; it was cool.
I finally surmised that the problem was with the thermal sensor on the motherboard. it had probably shorted or got soaked and was reporting the highest temperature it could as a safety measure, thereby limiting the CPU to a very low frequency and not allowing it to throttle above 503 mhz.
My last option, save for replacing the motherboard, was to find the sensor chip, clean it, dry it and hope that it would work again.
But this is not what solved the problem. somewhere on the net i came accross a code, that when entered on an Inspiron 9100 (an older laptop, with a different chipset) would bring up the Thermal Management screen or something like that, which is certainly not accessible via the BIOS. I was playing around with the settings on a program called Hardware sensors monitor, again to no avail, when i finally decided to enter this code:
FN key + zxcvasdqwer. almost the second i pressed z, or maybe after x, the high speed fans shut off! after a short while they kicked back into operation but at a low speed, just like they were supposed to. the program hmonitor began reporting a more realistic CPU temp. i tried to play a high-def movie file and finally it played normal, without any lag or stuttering! as i played it, the fans kicked into higher mode, and the temp which had been steadily rising, began to drop. the program, and most other programs were still reporting the cpu at 202 mhz, windows system properties as well. but since it was playing a 720p video file normally, it had to be much higher than that. i did a reboot and voila!
all monitoring software are now reporting the CPU at 1.73 ghz. the system temperatures are perfectly normal, and at idle the CPU goes as low as 20 degrees C. The software Speedfan, however, is still giving an error regarding the sensor chip on the motherboard.
I seemed to have fixed the severe thermal sensor problem by a few keystrokes, without having to replace the motherboard or even the sensorchip. in fact, i didn't even have to find the sensor node and clean it.
I came accross more than a dozen people who had a very similar problem to mine, with the temperature being reported at 85-86 C, for no reason. At least those who have a Dell notebok might be able to solve this problem.

I understand that sometimes mistakes are made and early versions of products are less reliable, but Nvidia seem to know exactly what the problem with the 8600 is but make no attempt to fix it...

my xps m1330's power adapter recently became faulty, so I ordered another one from eBay.
It just arrived today, but the problem is when the adapter is plugged in to the computer and a power source,
the green LED light flashes. Does anybody know what this means and how I can fix it?

seeing as I'm getting ready for my 1330's second Mobo replacement, I've made a list of what to check after a mobo replacement. The first part of the checklist is what you really should test while the RegGuy's still on location and the second & third parts are what you need to verify (in most part) that the replacement mobo is indeed ok.
What the rep will check on your behalf is that the Notebook fires up and loads your OS. This of course implies that the power-on switch, monitor, hard drive, keyboard and trackpad are connected and that the main chips (cpu, graphics, chipset, audio, etc) are indeed functioning.
But that's about it so the rest is up to you ...

my m1330 is showing signs of gfx/mobo failure, but there is no real way to prove it to the techs.
Is there a way to call in and get my mobo replaced without forcing the failure? ...

I never knew about the nvidia and the stupid faulty 8600 cards until i accidently saw it today. It makes sense why my laptop freezes when it comes out from sleep mode.
Now the question is what are Dell UK doing? I know my laptop is failing now. Can you get your money back because i don't want mine replaced by another faulty 8600 card.
I have a inspiron 1520 with 8600m gt. Its 1 year and 2 or 3 weeks old now. Fortunately i got 3 year warranty.

I have an inspiron 9300 and a precision m90. my m90 has the t7200 and is vastly superior to the now aging 9300. the chasis are very similar and the mobos look exactly the same, dimension wise, minus one minor detail, the rear usb ports are farther apart on the m90 mobo, not by much but just enough to be irksome and cast doubt.
has anyone tried to upgrade the 9300 mobo and have they tried it with the m90 mobo? I can live w/o that pair of usb ports next to quadrupling the performance.
ulimately, I am trying to save the great monitor and in great condition 9300 chasis and upgrade the mobo/processor/ram.
what have you tried, learned, and/or recommend to get the 9300 upgraded to close to or better than the m90 with t7200?

I have the XPS m1330 with the nVidia 8400 GPU. Got it back in September of 2007 with just one year warranty.
I just started getting the rainbow colored vertical lines on the screen today, did research, and found out it is due to faulty GPU design.
Called up Dell, and they said even my one year extended warranty due to this common GPU error was over in September of 2008.
They also said I am out of luck, unless I want to go through their out of warranty repair department.
I didn't use the laptop on regular basis till just 8 months ago when my old one finally gave out of me after 6 years. So m1330 has been only used for 8 months, and now I am stuck with bunch of verticals lines, and no hope.

My lovely Dell Inspiron 1720 notebook was working quite happily but then the next time I switched it on and used a browser it started filling the URL box with letter 'd' by itself.
It then returned to work normally for a minute or so but then started filling a page with the letter 's' then 'a'. Sometimes I can get it to stop doing this by pressing another key but 'a','s' and 'd' have stopped working altogether except when they spring into life by themselves.
Virus checker says it's clean. What checks can I run to determine if it is a driver fault or keyboard hardware fault?

I have two identical Dell Inspiron17R 5720's with the same problem with the Quote Key. When pressed once, nothing appears on screen. Press again and both appear. Get the same result if shift key is used for double quotes.
The same results get transferred to an attached USB keyboard, so it must be something wrong internally, either in Bios or Windows 7 (SP1)'s setup of the Standard PS/2 Keyboard.

So I've just bought a second hand studio 1640 from ebay (t9600 + 4670), got myself a 130w power supply and am running throttle stop (otherwise any games I play start to stutter within 20 mins or so).
I have noticed that the laptop gets insanely hot very quickly, even with the laptop lifted up a cm above the table to increase the airflow its at 100c on motherboard and nearly the same on CPU within 15 mins of me playing mass effect. i was wandering if anybody has any suggestions on how to make it run cooler?

I have a problem with my XPS 1730 laptop, this started probably 4 months ago. (second laptop that has screwed up after the warranty ended). I'm hopeless at explaining stuff, so i'll do it in point forms.
* First sign of trouble started when i booted up my comp one day and it beeped before loading windows and paused saying something like
"AC power adaptor not recognised, press F1 to continue F2 to enter setup, system will run slower"
If i continued then it did run really slow (even though power option was set on high performance) and the battery didnt charge.
* Every time i turned on my computer i had to keep putting the power cable in and out, adjusting it as i did so, until the battery light on the top right (near the lcd screen) flashed. If that didnt flash and i turned it on then the unknown power adaptor message would come up.

As I took my Dell Studio 1555 apart to upgrade the cpu (not a job for the feint hearted!) I took some photo's of the mainboard and HS/Fan.
If any of you have noticed high temps in HWMonitor on one of the ACPI I have tracked it down to be related to the GPU. Well when you look at the Heatsink you will see why!

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?

My mobo has been going bad. I've been slowly losing functionality. First, my multimedia card slots stopped working, then one usb port, then all usb ports and lastly my bluetooth module is working. I've concluded that I must have a bad mobo.
Is that the right assessment?
If it is and the mobo needs replacing which mobo do I use?
But let me be more specific, there are two types of mobos, a full-featured and a de-featured. I'm positive that i have the full-featured mobo but my problem is finding the right mobo with the right product number. I've searched online and the product numbers are all over the place. What's really confusing me is that I've found the same product numbers being used for both full-featured and de-featured mobos. So this makes it difficult to know which one to buy.
