my power brick making a clicking noise and the LED light sort of flickering in conjunction with the noise. Does anyone else have this issue? I'm not sure it's a problem, but I'm worried that it might be.
View 4 RepliesI 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!
I would like to bring this to attention for the community, as it recently happened to my SXPS1647. This happens with the 90w brick and only on certain firmwares. The proc in my system is the core i7 620m.
One night just before bed i closed the lid on my laptop to put it to sleep and then turned off the TV, but then i heard a strange high pitched sound coming from the laptop area. I went back and investigated and there was a strange sound coming from the power brick. The best way I can describe it is the sound of electricity moving, a wave like sound that gets higher and lower pitched. Very concerning, so I call Dell and tell them the problem they send a new motherboard and ac adapter.
The dell tech comes to my house and says that's the strangest thing he has ever seen/heard. So he tries the new ac adapter and same sound so he replaces the mobo. With the new mobo the sound is not present, so im happy. But the computer was throttling really bad so i decided to check the bios with CPUZ and it was A01. I decide to update the bios to get rid of the throttling issues, A05 update went nicely but as soon as I restart the system the magic high pitch sound has returned. The previous mobo had the A04 bios when it was making the sound.
I recently read the whole 90w vs 130w ac adapter and wonder if that has anything to do with this issue?
If your battery is mostly drained and you plug the thing in, within minutes the brick gets so hot that I'm afraid to let it sit on any surface, much less touch it.
I thought it might just be a defective piece so I got a replacement power adapter and it gets just as hot as the other one. Has anyone else noticed this?
So I'm about to get my XPS 1647 today. I don't plan on gaming too much, so I don't know if I'll hit these throttling issues, but..
How do I know if my system is throttling or if its just running as fast as it can? Does the 90W power brick heat up? Is there some system monitor I can check?
I have an XPS 1330 and my wife has an older Inspiron 6000. The power cord on her Inspiron 6000 went bad. My adapter has an octagonal shape on it so it won't work with her notebook. However, my slim 3 in one travel charger does fit her notebook so we've been using that
View 7 Replies View RelatedWell many people seem to suffer from the dreaded brick Failure, I have had a few go crap, and many of those failures usually were traced back to a broken wire in the DC cable assemly. If you wiggle the cable in the area if the strain relief you can usually hear the crackling sound.
I usually find it breaks in the strain relief - See attached Picture.
Fixing this can be easily done with a few items, there are a few little challanges as well.
1. Soldering Iron & Solder
2. Solder Sucker (removing tool) or Solder Wick
3. Wire Cutters
4. pliers, Small Screw drivers
5. Volt Meter (DVM)
6. Electrical tape
If you see Picture 1 of the plug, I just wanted to point out the typical barrel type connector used in the Dell laptops 6000/6400/9400/M1710 Etc.
There are 3 wires to connect here, The Out side Barrel is the Negative supply, The inside Barrel is Postive, and the inside Tip is a Voltage Sense.
I have added some new Pictures to show the inside of the PA-13 brick.
You can see the three connectoins on the bottom side of the board. The spacing is tight, and you can easily solder across two pads, checking for solder bridges is important
Please note, the spaces are small, and you require good eyes, a magnifying glass would help, and some soldering skills.
After your soldered the new connections careful inspection to check for any solder bridges is required.....
Just got one of these, and the power brick is well erm.. a brick!
I need / want to get a third party one that is hopefully smaller, so does anyone know of one suitable? or, if not.. know of what i should be looking at to try and find one?
Is it normal for the power brick to get hot? When I say hot I mean, it's so hot I'm afraid to leave it plugged in and go anywhere. I just got my system the other day but really haven't messed with it so far (except for making sure everything was up to par.) Today I started getting into everything, clean install, etc and I noticed like after 10 minutes of it being plugged in (120 watt brick) the brick was so hot it felt like my heating pad on high. I've never experienced this before, is this normal?

View 9 Replies View RelatedI keep my computer plugged in when I'm at home, but my power cord keeps "shutting itself off" and stops charging. So sometimes I check my battery power and there's like 24% left. My battery seems to be holding a charge for now, but my power cord seems to randomly fail. Never in my life have I ever heard of power cords failing-I'm sure it happens but this is ridiculous.
View 6 Replies View RelatedHad the Studio since Wednesday and its great!
However, the power brick has started to make noises? A series of about 10 clicks in quick sucession repeated twice in a couple of seconds.
It will then go quiet for a while then do it again?
Its also pretty hot, too hot to touch for a while and its hot quickly - in about 10mins from cold.
Should I get a replacement or is this normal?
How do I go about getting it replacd? Sounds like its shorting or something?
The power supply they sent is not only the wrong wattage rating, it also won't even FIT into my laptop's power input.
I emailed them, and they won't even replace the thing.
"I reviewed your order details and I see that 65 Watt power supply is listed on your order details therefore we are unable to send you the 90 Watt power supply as per
Dell's Exchange guidelines, an exchange could be done for like to like items only."
I just downgraded my xps m1330 to window xp. It seems to be running well. But whenever I connect the power cord to the laptop, everything slows down. It takes way more time to load the window
View 6 Replies View RelatedIs anyone else having a hard time keeping the M1730 power cord plugged in to the back of the laptop?
Mine is constantly falling out.
I purchased an Acer Aspire 5740 laptop, which I quite like except for the awful beep it makes when the power cord is plugged in or removed from the laptop. Is there any way to disable this beeping sound?
View 10 Replies View Relatedif this has happened to any notebook user:
for a week now, my ac adapter/power cord has been making crackling noises when i unplug it...at first i thought it was static electricity, then today, I saw smoke coming from it
it won't work for awhile, then it will magically start charging my notebook
it seems really dangerous & i'm afraid it's gonna catch fire or burn me.
First post here...
Here's the deal, my 600m won't charge the battery anymore and will not run off of the power cord.
The power cord is showing 19.5v which is correct.
The back of the power adapter jack on the mobo is showing about 3.5v when plugged in and the two outside pins that charge the battery are only showing about 0.02v. Is this normal voltage or do you think the mobo broken?
I'm not really sure which of the battery charging pins to check the voltage from and can't find a diagram of it anywhere.
My D600 will not boot up unless the power cord is plugged in. Is there some switch that I hit by mistake? Can this be corrected?
I guess basically it doesn't work on the battery unless it is plugged in but the power shows 100 % for the battery
Travelmate 4010. I've had it for about 3 years now, and over the past *thinks* 6 months or so the power cord had been replaced twice because it broke. But it wasn't really the cord itself that broke the first time. Something inside the jack is broken and now the cord (a new one) has to be positioned just the right way so it doesn't switch to battery mode. I use it mostly on my bed, which probably doesn't help, but at one point I had to have it on a desk with the cord taped to the lid so it wouldn't move and kill the battery (which doesn't last that long). I couldn't even close the lid so I just had the monitor shut off after a minute. but I did get a new cord and started using it on my bed, storing it underneath when I'm not using it. After a while, though, the cord started to do the same thing and now I'm sitting here trying not to move on the bed too much so it doesn't disconnect. I'd like to get a new notebook, but I can't afford it.

Lenovo G500

I have a Latitude E5520 that is having some strange issues. If I have i plugged in to a power cord, close the lid and disconnect the power cord, the unit shuts off. Sometimes when undocking, the unit will shut off as well.
I have checked the power settings and confirmed that when the lid is closed, no action should be taken.
The battery is fully charged and the laptop runs fine on the battery.
This has the latest BIOS revision A09.....
I wanted a quiet laptop along the lines of the T400 or the macbook pros. These are quiet enough for me. I owned a Vaio Z in early 2009 that I got rid of purely b/c of the fan noise. Can anyone tell me if the newest models or a vaio fan control type of software or BIOS upgrade has made the VAIO Z series quiet? Otherwise this was a great laptop.
View 5 Replies View RelatedI have been looking online and getting mixed results regarding buzzing noises from ac power adapters. My old hp dv6000 laptop powerbrick did not make buzzing noises as loud as my new dv6-1235cl from costco.
I noticed that a lot of people now hear buzzing noises from their ac adapter. Then I came onto this website.
[url]
Is this a bunch of bs or are they for real?
I can hear the buzzing noise when I put my ac adapter on the table, but almost non existent when its on the ground. I want to know if this will be a fire safety hazard in the future? I dont want my house burning down even when this thing is plugged in.
So last night my laptop was running fine on battery power, but then it was running low, so I plugged in the power cord. Nothing happened. Since the adapter at the laptop end was falling apart and duct-taped anyways, I figured it was just conking out, but then I saw the indicator light on the power brick was off.
With some experimentation, I found that if I moved it to a different outlet, the light would come back on, but if I plugged it into my laptop, the light would die, and I would have to again move it to a different outlet (the same one as first would work fine) to get the indicator light back on. It works in other Dell laptops. Other adapters do the exact same thing.
So I'm guessing there's a problem with my laptop wiring that's causing a short or something. (Apologies for my shallow electrical knowledge.) But it was working last night on battery power. Until the battery died completely this morning, it would power up. So it's not an electrical problem that kills the laptop.
I've had my laptop for a little bit under 2 months, so these are the things I have noticed.
Issue number 1: When you plug in the power cord into the computer, the screen freezes on what it is currently on. I noticed this issue because occasionally when I plug in my power cord, and try to use the mousepad to select something, the mouse pointer is gone! I have to unplug-replug the power cable to get the mouse pointer to show again. It seems to have to do with the screen
Issue number 2: when I carry my E7440 around in my bad, or have it shut for long periods of time >3 hours (I just simply close the lid), the computer will SHUT DOWN. The thing will shut down completly, even though I simply closed the lid! At first I thought it was just going into hibernate, so I disabled hibernate in my power settings. But nope, even when the computer is asleep, it will occasionally shut it self down for no reason at all.
Just now, I closed the lid on my laptop, and put in in my bag, then walked to my office about 10 minutes away. When I sat down at my desk and opened my laptop, to my surprise, it had shut down by itself! All of my open windows, browsers, and applications were closed, and upon opening chrome and microsoft word, I was greeted by "your browser did not shut down correctly" and "microsoft word has recovered files". This points to the conclusion that it was not hibernates fault, but instead a issue with the laptop itself shutting down when it is put in sleep. This issue needs to be rectified immediately if it is a widespread issue.
Issue number three: When the computer comes back from hibernate or sleep, the computer is very very sluggish, even when plugged in. It is sluggish forever, OR until the power plan is set from whatever it is to "high performance". upon switching to the previous powerplan from high performance, the swiftness of the system is restored. This indicates to me that the system is throttling itself after it resumes from hibernation, why. This needs to be fixed; many people (myself included) just thought that the system itself was slow and underpowered, not realizing that it was just throttling itself when it emerged from sleep or hibernate.
Have this laptop a couple of months for sons schoolwork. Now it wont stay on unless power cord in. When its on, verything goes fine, it battery icon says its at 98%avaliable (plugged in, not charging). As soon as cord is out, it dies completely no power even when start button pushed.
View 3 Replies View RelatedI have just downgraded my T7200 CPU to an T2300 so that the CPU temperature could go down. And that it did. from 68 degrees to 45 degrees in idle but stil the fan is going at it at full speed even at 45 degrees.
I found a post on this forum were a person says that the BIOS has to flashed whit an modede version of the bios file. But how do I make a moded bios?
Its from this topic that I found out that the BIOS has to be changed so that the fan only runs when it needs to and not when it works under normal idle CPU loads:
SZ fan noise?
getting my Sony VGN-SZ48GN fan noise down to a reasonable level?
why is C1E disable on the VGN-SZ48GN and how do I enable it?
I've recently purchased Sony Vaio FW21E (European model) and to my surprise, I find it quite noisy (contrary to what you can read in many reviews).
The first problem is HDD - I've owned 3 notebooks so far and no one had such a noisy disk. I almost thought that there is some kind of motherboard or GPU fan in there until I opened the case to confirm that the noise really comes from the HDD. It is quite unpleasant in a totally quiet room (like in the night) but I can hear it even during evenings when the room is relatively quiet. Vaio owners with Toshiba MK3252GSX disk (320GB), do you experience the same amount of noise? (On the upside, the performance is really nice compared to my older laptops, Windows Experience Index being 5.4.)
The second problem is the main fan (which I understand is the only fan on this Vaio). It is quiet for the first hour of usage or so but then it always turns on for about 5 minutes, then it's quiet for another 2-3 minutes, then it goes off again etc. etc. I really find this annoying because the fan speed is changing frequently and rapidly (i.e. from zero to high spinning, then it slowly goes down to what I would call acceptable level, then it stops rotating immediately; then it goes of for 100% again etc.)
When you combine these 2 noises, the notebook is quite unpleasant to use in quiet conditions. From the right hand side where the disk is placed, you constantly hear a whisper-like sound while from the left side, you are distracted by the main fan which tends to be turned on and off in a few minutes intervals..........
Ive had this laptop for 3 months and Im quite dissapointed about the fan noise - it is running constantly. My experience is that the fan is running in 3 modes: minimum (always), medium (short time) and max (when using graphics ex.). Sony Support told me that it is normal that the CPU fan is running when the computer is swithed on (=CPU on).
My experience with laptops though is that they are quiet all the time, but eventually starts the fan when using many applications (graphics ex.). The symptom is the same in Windows XP, Linux and FreeBSD. Is it normal behaviour - I mean, should it run constantly or occasionally?
