View 10 Replies View RelatedDell :: Far Left Fan Making Grinding Noises
Nov 20, 2009Whenever I'm viewing the smallest things, like images or even streaming on youtube. The far left fan goes into gear -- but it sounds like it's hitting a wire, making a loud and obnoxious grinding sound.
And recently my computer would go at 100% CPU Usage, requiring me to restart a couple of times until it became neutral.
Any ideas other than opening the computer?
I'm using an Inspiron 1520. It's 2 years old.
Dell :: XPS 13 Making High-Pitched Noises
May 27, 2012I just purchased the Dell XPS 13 Ultrabook and I hear a lot of high-pitched noises coming from the keyboard, i think from the right side, but hard to tell. It is really noticable in a quite room, and isn't a solid tone, it has a super short pause in it every second or so, but overall very consistant. It isn't the fan, and when I use Fn F2 to disable wireless/bluetooth it gets a little quiter, and seems a little more constant in the tone. It also isn't the lighted keyboard, it still does it with that off. It also does it when using A/C or battery.
So it might be a combination of the harddrive and wireless and bluetooth, or maybe some other circuits, but it is very annoying. I've seem some others post online about this as well, and am hoping Dell has a way to correct this somehow, but I don't have a lot of hope that a software or firmware update can fix this.
Are others hearing this too? I know some people are more sensitive to these types of noices, but if you put your ear to the keyboard in a quite room, you will hear it. I can hear it when I am sitting up typing at the keyboard, I just put my ear to the keyboard to better tell where it is coming from to describe it.
Dell :: XPS 1340 DVD Drive Slow, Making Weird Noises
Nov 22, 2009I just received a new XPS 1340. It's got the TS-H553A DVD burner drive. However, I think there might be a problem with it. It makes a weird scratching noise with most discs - almost like a power saw cutting through wood - and it rips CD audio at 1.5x.

Jun 1, 2008I've had this aspire 7720-6381 for about a week and a half now. I've been very satisfied, and have even been content with the mediocre laptop speakers it contains. I wasn't expecting much in that realm anyways.
The problem I have is that periodically the speakers will make an annoying clicking noise. It's pretty sucky. Even worse, after a time all sound will screw up and a deathly fuzzy roaring sound is all that is heard.
Acer :: Aspire 5920 Making Strange Noises After Spill
Mar 22, 2009A few weeks ago I spilled green tea (no milk or sugar) on the desk around my Acer Aspire 5920 laptop. The tea went into the back left quarter of the machine, mainly through the ventilation holes and the ports on the left side. I removed the battery, drained the liquid, and let the machine dry out thoroughly. Since then the machine has worked fine. However, it occasionally makes strange noises, especially on start up. It's a fizzing/popping noise, in short bursts, like static. It sounds as if it's coming from the loudspeaker.
does anyone know the machine well enough to diagnose the fault? Only the components in the back left quarter of the machine got wet. Could there still be water in there? Is the noise a sign of a serious problem? What can I do to fix it? As I said, the spill happened several weeks ago, and, apart from the noise, the machine works fine.
Dell :: Is There A Power Supply Gremlin?
Apr 26, 2009I’ve seen 2 fairly new Dell laptops recently (a Latitude D520 and an Inspiron E1705) with the same symptoms. With a known good adapter attached to the unit, they do not charge at all,
but they run off the battery until the battery dies. I disassembled both and checked the connection between the power jack and the mobo and found them to be solid.
I connected a power source directly to the + solder point on the mobo and a ground and found they did not power up at all. If this were a desktop, I would change the power supply immediately, but being a laptop, I’m not sure what (if anything) can be done to fix the problem. Any ideas or suggestions would be very much appreciated.
What I've done:
1. Both units work normally with charged batteries, so I know I'm working with good laptops.
2. Removed, cleaned contacts and re-inserted RAM.
3. Cleaned accumulation from the internal lint trap, i.e., from the CPU cooling fins.
4. Removed, cleaned, re-applied thermal paste and reseated CPU'
Dell :: Universal Power Supply
Sep 27, 2009So i have a new e6400 moved from an e4200. Figured I could use the nice dell travel adapter I had with my 4200. Once i plugged it into my new beast i got a not enough wattage message from DCP.
Which is fine, I now realize that my nice slim power adapter is very much under powered for this laptop.
I went out and got a Cooler Master SNA 95 it is a 95 watt adaptor and acutally is really small and light. Got it home and plugged it in and I got this message .....
Dell :: E6400 Connected To Power Supply

Dell :: Power Supply Model # Matter Much?
May 1, 2010needed a new charger, dell listed 5 options for my service tag #. So I called them and the guy in india said said the NF599 was the one I need if I wanted the 6' cord.
Put NF599 into amazon and ordered one, received a UU572. Specs all appear to be the same, this one doesnt say 90w anywhere on it but the specs online all say 90w. Its also a 3 prong and not a 2 prong like the NF599, that may actually be nice so it doesnt fall out of the socket so easily.
Dell :: 1730 Faulty Battery/mb/or Power Supply?
Mar 6, 2009I 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.
Dell :: Proper Part Number For 130 Or 150 Watt Power Supply
Nov 3, 2007I've recently upgraded to a Quadro 2500m in my 9400. Sometimes after playing games for awhile it will freeze up for a second and then get really slow (sometimes staircase like lines will appear on the monitor). I doubt the 2500m is broken since it came in a sealed Dell box and my temps aren't too high, so I'm suspecting that the 130W adapter that I got off of eBay is not really up to it. I noticed that sometimes when it boots up it cannot recognize the adapter (Press F1 to continue, F2 for setup etc...) but other times it recognizes it as the 130W adapter fine.
I also noticed that that PA-13 that I have was made in 2004...isn't that way before any of the Inspiron 9400s came out?
So I'm wondering if anyone knows where to get a reputable 130/150W adapter and/or what the part numbers are that people have been using successfully.
Dell Inspiron 15 :: Will Not Boot Up - Power Supply Light Blinks On And Off
Feb 5, 2013My Dell Inspiron 15 will not boot up. Started randomly shutting down over a week period. Would also display a plaid screen which would require a hard shut down by me. I was trying to run Dell diagnostics on it and noted that the video card failed, but it could not complete the diagnostic without shutting down. Now the power supply light blinks on and off in a 10 second interval.  It acts like it has no power, but I know the battery was charged.Â

May 4, 2010I have a 12'' sony vaio with a 16V power adapter. My battery is not good anymore, it was not even holding for 20Min, but my problem now is that the computer does not turn on without the battery at all. I have to leave it charging for hours, then it will go on, but in the middle of the windows loading process it shuts down and does not show any signs of life until you leave it charging for another hour.The voltage output out of the power supply shows 14.70 ~ 15.20 never gets to 16V. Now, comes the questions...
This particular laptop needs a good battery to " buffer" power and the AC adapter only charges the battery but does not have enough Amps to run the computer without the battery?

Do i have a Bad power adapter that is not even charging the battery properly?

Sony :: Kensington Universal Power Supply & VGN-SR Series
Feb 16, 2009Anyone use one of Kensington's universal power supplies with their VGN-SR? Trying to figure out which "smart tip" to use.
Their compatibility wizard on the Kensington website doesn't list the VGN-SR290; only lists a Vaio SR series. I think this may be referring to an older series and not the VGN-SR line. The tip the wizard recommends for this 'Vaio SR series" is N15, which, according to the power supply instrcution manual has output volatge of 15-17V. Another tip, tip N27, has output volatge of 17-20V. The power brick that came with my SR290 indicates a 19.5V output (Sony VGP-AC19V25 - 19.5V, 4.7a)

View 4 Replies View RelatedLenovo P/Y/Z Series :: IdeaPad Y510P Will Not Recognize AC Power Supply
Jun 15, 2014I have just received this laptop. I followed the instructions out of the box, installing the battery, then connecting the power. The battery started charging that first time, but after that, any time I tried reconnecting the A/C power supply, the laptop would not recognize the adapter and I am not able to charge my battery.Â
Â
I have tried the following steps:
Â
1. Shutting down the computer, removing the battery, and starting the computer from the A/C power supply. The computer will not recognize the A/C power supply to turn on the computer.
Â
2. Updating all the power management drivers. Everything was already installed properly.
Â
3. Using the Lenovo Energy Management battery gauge. I must have the A/C power supply plugged in to use it, but the computer still won't recognize it.
Â
4. Held down the power button for 30-40 seconds then reset the BIOS to default settings. No change
Â
5. Tested my outlets and connections between my AC adapter cords. Everything is working properly.
Â
There is one way that I can get the computer to recognize the AC adapter, and that involves all of these steps shown below, but when I unplug the AC adapter I am right back to the beginning, and I have to redo the whole process. I have just received this laptop and I am quite sure that you shouldn't have to go through this process every time you want to recharge the battery, or use your computer while only powered by the AC adapter.
Â
Steps I have to take to recharge my battery:
Â
A. Disconnect the A/C power supply.
B. Shut down the computer.
C. Remove the battery
D. Connect the A/C power supply
E. Start the computer.
F. Uninstall all battery drivers that are labeled Microsoft ACPI Compliant Control Method Battery (which come back every time).
G. Shut the computer down.
H. Disconnect the A/C power supply.
I. Insert the battery.
J. Insert the A/C power supply.
K. Start the computer.
Â
That is the ONLY way I have gotten my computer to recognize the A/C power supply. I know the power supply is functional, but why I have to go through all of those steps for the laptop to recognize it.
Lenovo T400 / T500 :: T540p - Intermittent Power Supply Connector?
Nov 3, 2010Symptoms: Laptop switches off unexpectedly; unexpected failure to charge battery; random changes in brightness. Messages appear such as: "This AC adapter may not provide enough power to your Lenovo computer. Please reconnect the proper AC adapter"; "Battery 2: There is an error"; Do you want to switch to 'Airplane in-seat power plan' (if this option is enabled in Power Manager).
This is why I think the power connector is to blame: I opened Power Manager to the Battery tab and also ran BatteryInfoView by Nirsoft. With the power connector firmly plugged in at the back of the laptop and with "90W AC adapter is attached" showing in PM, moving the connector slightly from side to side often triggers one of the symptoms. The two apps then indicate that the AC adapter is no longer present and that charging has stopped. In some cases vibration due to typing or moving the laptop is enough to trigger a symptom.
Supporting evidence: After I taped the power adapter's output cable to the laptop so the plug cannot easily move in its receptacle I found the symptoms stopped (see photo).
Summary:This is a serious annoyance. It means I can't rely on the battery being properly charged when I need it, or that the machine will stay running when I leave it unattended.

Lenovo X Series ThinkPad :: X200 Will Not Operate Without Power Supply Plug In
Sep 3, 2014My X200 (three or four years old) has a new battery (few months only) and has never had any power issue. Suddenly since last week it will not operate without the power supply plug in. Â Battery is showing 100% and condition excellent, but the second I remove/unpower the power supply plug, the system crashes. On restart with power supply attached, the battery indicator shows 1%! Â It then gradually creeps up to 4% and after maybe 5 mins it leaps back up to 100%.

If i have full battery and try to boot without the power supply i get a blue screen after being about 60 seconds in the screen where the windows logo appears.

I think its possible, that i have made some failure with the drivers. The ThinkPad Power Managers always stops working after booting. So i have removed the program by using the "msconfig" functionality.
Dell :: Power Adapter Making Sounds Xps 16
May 5, 2010Have had my xps 16 for a few weeks. my power adapter is making some strange sounds. It's kind of like a really light fizzy/crackling sound. The best way to describe is that it sounds like a soda/carbonated beverage. Not all the time, just sometimes. I thought it was just random, but I was using it earlier, and noticed it made the sound when I was doing some task on the computer, i.e. scrolling down on the touchpad, or opening a folder, etc....????
Anybody experienced this? It's the 90W adapter, and I was going to call Dell and get the 130w anyway, but does anybody have any thoughts?
