I don't know if I shoudl be posting this in the M4400 thread, so please accept my apologies if it should be.
I'm a proud M4400 owner, and have been for a while now. However, I just installed Win7 x64 (upgrade from Vista x64), and the first thing I did was install RMClock then undervolt it. I'm very familiar with doing this, and with overclocking/undervolting in general (my PC is a 4.5GHz Q9650!).
After undervolting it to 1.025v at the 10x multiplier I set about to do some stress testing, whilst also monitoring temps with coretemp.
I guess for temp measurements to be meaningful we need to start with Ambient temps. In my room it is probably around 13-15C (55-59F), as in too cold to sit around in a t-shirt (I'm in Austria, it's winter, and the heating isn't cranked because I like to run my computer cool!).
I currently own a HP DV4 1275mx laptop. I have had it since April 2009. This is a product replacement for my DV2000 that had the bad nvidia chip and left this world. It only lasted 9 months.
Here are my issues (i do say they are eerily familiar)
Its freaking hot as a volcano. So hot that I can hardly use my touchpad mouse without it hurting my fingers. I thought I was just being paranoid when I first got it since my last one got hot and then out of nowhere just died. So, I downloaded speed fan a few months ago once it started to really worry me.
The temps range from at the lowest 65C and will get up to 105C. I called HP support right away (3 months ago) they ran BIOS updates and all of that and sent me on my merry way.
Well now it likes to just shut itself off (i'm assuming a fail safe so it doesn't blow up on me). It takes a good few minutes and at least 3 or 4 tries to get it to boot up all the way again. Called HP again, ran the same updates and some diagnostics that my computer couldn't even get through without overheating. They are having me send it in for repair...............
My wife's Inspiron 1545 from late 2008 is having a new issue wherein it is randomly shutting off but not due to heat. The computer will shut off when not connected to AC power randomly. Sometimes it will last 10 minutes, other time 40. What's odd the is computer reads anywhere from 50% - 85% battery life left.
I'm certain it's not overheating because it doesn't get hot. Also,I disassembled rear cover and reset the CPU cooler with new thermal paste as a precaution yet the problem persists.
I ran the boot hardware diagnostic test all the way through with no errors. The harddrive has no audible clicking/crunching which usually indicates an HDD headed south.
My HP G62 Notebook PC has been overheating and shutting down all of a sudden recently. I have tried all of the recommended fixes I can find (cleaning vents, downloading bios, etc.) but to no avail. It is well ventilated and all vents are clean.
I think that it is an overheating problem considering my laptop (ONLY recently) seems to be getting very hot, to the point it needs to shut down. But this is the strange thing:
I had Windows Vista installed on this laptop (Acer Aspire 5100) earlier, and my battery almost never heated up to the point it needed to shut down, or even heat up to an extreme level.... But now that I have downgraded to Windows XP SP2, it seems to shut down MUCH more often. But I did find one thing of concern. Around the same time my laptop started shutting down, I installed an application called 'Game Speed Changer' and that whenever I had used it, it slowed my computer down immensely, and then when I went to close it, the BSOD would appear. Every time.
I'm in the repair field and I've got a customer's Aspire 5520 that was brought in for overheating. The machine had gone to Iraq, and the customer has indoor dogs..so yes, the fins on the heat pipe were very clogged. Got it all cleaned out, and the machine is still shutting itself off after between 10 minutes and 30 seconds of use.
Now, the machine isn't overheating. SpeedFan and a few other CPU temp utilities are showing the CPU to be around 45*c when the machine is randomly shutting down. 45c is not what I'd consider hot for a Turion x2.
It's not a RAM issue, I've replaced the CPU and am getting the same symptoms.
I've bought the Lenovo Y560 laptop ~1.5 years ago and I've been very satisfied with its performace overall, but I've recently noticed, it overheats and shuts down when playing newer games (doesnt appear in games like WoW or LoL or similar low end system req games). And we all know why we bought such a high performance machine (and it isnt to use Facebook).
I've installed Hardware Monitor and my idle temperatures on my i7 are ~60 degrees and my GPU is ~55 degrees. Seems pretty ok I guess. Under heavy load, they exceed 97 degrees and thats when the system shuts down, beacuse of thermal protection.
I've tried testing with bios 71 and bios 59, but the problems persist and I didnt really notice much of a difference, but I have read that under some bios the fan doesnt go over a certain %, but never reaches 100% speed. I've also updated GPU drivers and energy management thingy.
Now, I have come to two solutions - I am going to clean the pc today, apply new thermal paste and blow out the dust and stuff. The other is, but I dont really want to do it, is to cut the blue wire that is the fan control one, but then the fan would be at 100% constantly, which is just not needed (noise and stuff).
Those underload temperatures are measured with my cooling station active (homemade from 2 old GPU fans).
I got my new laptop last week, arrivied with BIOS version A03 loaded so I immediately flashed it with A04. All was working nicely for a few days and then suddenly I've been experiencing random shutdowns.
After reading through every thread I can find on the topic, most people seem to think that A04 fixed the shutdown/overheating/fan problem but it would not seem to be the case for me.
Has anyone else had similar issues? I'm gonna give Dell a call tomorrow and get the low-down but would be nice to hear from anyone in the same boat.
Sometimes when I choose shutdown, the computer goes through the shutdown process but restarts right away. This happened twice in a row. I'm not sure if this is related to power settings (High Performance, AC plugged in). Eventually it'll stop but it's kind of annoying because i have to wait until it fully turns off and make sure that it doesn't restart.
I got a refurb Studio 16 with RGBLED display last week. Had a few dead pixels and had the screen replaced with next day service. The technician did a good job, although I almost had a heart attack watching him strip the laptop apart.
The new screen looks great, but now the machine is randomly shutting down (NOT gracefully). I haven't actually witnessed it, but instead of going to sleep, when I come back to the laptop after an extended period, it's off and Windows 7 is complaining of an improper shutdown.
Event log shows:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
I am facing a strange problem with my Studio XPS 16. It was working fine with no BSOD, crashes, hang-up etc for a week or so.
I was watching a movie this weekend and laptop was on batteries. Well by the time movie got over only 15% of battery charge was remaining (I am having a 6 cell battery). I plugged in the laptop for charging.
After while I shutdown the laptop and surprisingly after Windows did the shutdown the Laptop was not shut down and the white light on the power button as well as on both sides of the laptop (on the side of hinges) were blinking i.e
I just purchased a new E7440 recently and most of the time, it will not shut down- the power light stays light, but display is off and the HDD light blinks every few seconds. If I leave it, it hibernates eventually but only shuts down when I actually hold down the power key.
The same thing happens if I restart instead of shut down.
New inspiron 14z. It seems that the fan is very noisy almost all the time the computer is on. It gets louder and softer according to what programs are open, but it's never really quiet.The real fun starts, however, once she opens a graphics-intensive program . The computer gets so hot it's hard to touch it, and after a while it'll just shut down itself without any warning.Is this a common issue with the Inspiron 14z? What should we do?
I have bought a new laptop, Dell XPS 14Z, 14 inch, with Windows 7 Premeium installed on it. However, I have a couple of problems from the very start which makes me regret buying it. The laptop works great, but sometimes when I try to shut it down, it doesn't. Just a blue window with shutting down sign but it never turns off perfectly.
The second problem is even deadlier. A blue screen, once a day or two days once appears and I never know why. This death screen comes from nowhere without any reason, I scanned my computer and there's no trace of virus. The only think recognizeable from the screen is this file 'tixhci.sys" file.
The laptop is very good in terms of hardware, 2.5 CPU i5, RAM 4GB, 500GB of hard drive and 1GB of display card.
I have replaced mother board and LCD of my Inspiron N5010. After replacement, it started to shut down constantly, usually 5-10 min after start up. I have run diagnostics, it showed error 2000-0413 (LCD cable not detected), but could not finish all diagnostic process, cause it shut down again during CPU memory test.
Is it possible that because of this error computer shut downs then working or it is two separated problems? Can it be that only cable connector causing error or it is a defect of new mother board?
I have an out of warranty 15" XPS that will just shut down at random intervals, doesn't seem to be heat related as it will sometimes do it immediately after turning on, doesn't seem to make any difference if its plugged into the mains or on battery either.
Run dell diagnostics at start-up and no problems were found.
Machine will usually turn back on fine, sometimes the battery needs to be disconnected first though...
Currently running Windows 7 64 x and tried with fresh Windows 8 install too (feels more like hardware really)
My laptop will randomly turn off. I don't think that it is overheating because sometimes it just shuts off like 1 minutes after i turn it on. I don't feel any heat coming from the fan or anything. When it turns off it doesn't go through the shutdown process it just turns off. Iv'e tried a factory reset and a complete virus/malware scan.
new dell inspion 3421 running windows 7,64 bit. my laptop does not shut down completely. When I shut it down, it logs off screen goes black and still the fan is running and the front power light LED is on. I have to long press to power button to completely turn it off.
The same happens even in case I out the laptop to sleep or hibernate.
I have a problem with my 15R. It shuts down "for no reason". Right now it takes him up to 20 s to shut down so there's no time for any diagnostic software:
it shutdown in BIOS too it shutdown with battery only and AC only it shutdown with HDD, CD, SD card reader, WIFI... and everything else that was unpluggable it DOES NOT shutdown without RAM it shutdown with any combination of my 2 RAM DIMMs after a long break it needs ~20 s to shutdown, 10 after a short break
I suspect it's a thermistor as the fan makes a lot of noise even in BIOS. So my question is - what could be the problem and where are 15R thermistors located so I could check if they are fine.
We have a user whose Latitude E7240 shuts down every time she tries to dock or undock her laptop. We have replaced the motherboard and both docks that she uses. The problem disappeared after she worked, undocked, several days from home. She returned to work and was able to dock/ undock with no issues. I have another motherboard, and can replace again, but not sure that the motherboard is the issue.
The problem Im currently having with my laptop is that every time i turn it on, it last about 4 seconds before it shuts down. I can only see the power and battery light on before shutting down. I dont even see the screen turning on. I try going to diagnostic mode and the only thing that changes is that my keyboard lights go on, but then after 4 seconds laptop shuts down. What to do or what might be causing this??
Ive got a two year old latitude D630 that is shutting down right after the Dell splash screen. pressing down on the left side of the laptop while its booting up and that worked to the point where I got to the login screen, but after a few seconds, it just shut down again.
My specs:Dell Inspiron 15Intel Pentium processor 2.10 GHz4GB RAM500 GB HD
Every time I try to play games, such as Terrarria, The Hidden, Half Life 2, Killing Floor, etc.my computer shuts down. I make it about 5-10 minutes into a game, and it just shuts off. It might be overheating, but I keep my computer elevated, and theres good ventilation. My computer never used to do this. What could it be?
I have a dell Inspiron n5050. It was a hand down from my dad who hardly used, only used it for check his work schedule. Well it was working for years and then I was playing games like league of legend, sims etc. It never shut down till I maybe late 2014. I would turn it on, everything is all good, I can log in. But maybe 5-10 maybe more minutes of being on, it goes black or a message comes up saying "the instruction at referenced memory at could not be written " I don't know what is happening or what I done wrong. I can't get a new laptop or anything due to money issues at the moment.
