if 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.
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 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.

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?

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
Model name: 20236
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.....
so just what the title says,
View 10 Replies View RelatedI've been thinking about buying a new power adapter to replace el-giganto that came with it. I understand that there is at least one Kensington power adapter that works (model 33197). That one, IMO is a bit too large. Curiously, that adapter is not directly visible on Kensington's website for Laptop Power Adapters, but is searchable (by part number).
So my question is whether there are any people out there that have used, for example, the model 38066 or the model 38067 successfully? Those two models are smaller (physically) than the 33197, but they don't actually list the Wattage they provide (they're listed by Voltage and Amperage - which kind of makes Wattage, but not exactly). It seems as though they might be 90W adapters (as the product pages make continual reference to their power efficiency over "other 90W adapters" which leads me to believe that they're probably around 90W adapters.
Or whether the model 38031 or 38030 will fit? These adapters are a bit larger, but appear to offer more input amperage. Though they also say "Up to 90W output" so ...
From what I understand, the HP Envy 15 will throttle the machine with less than 120W of input wattage.
Also, the 33197 is apparently an "old model".
I am in need of a new AC adapter for my HP Envy 15. Can any of you veteran owners recommend me a reliable and quality one (and hopefully under $100), preferably with a decently long cord?
View 3 Replies View RelatedSo 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 am trying to find a power adapter for my HP dock XB3000, however, everywhere I look, the power adapter seem to be the same. My laptop uses the newer smart pin connection, however the dock uses a smaller plug. When I look on ebay, I see they list practically all hp laptops to be compatable with their power adapters. I was just wondering if the power adapters are practically universal, other than the difference between the 65W and the 90W adapters.
View 4 Replies View RelatedSo while I was getting a blu-ray burner and HD upgrade for my DV5t, I got a promo advert in the mail from HP and it mentioned their Slim Travel Power Adapter (with USB charging port). I travel about 4000 miles by plane every 4-6 weeks, and I carry my Dv5t with me in a shoulder bag. After putting my laptop in a neoprene sleeve before putting it in the bag next to my paper file, there is not much room left in the bag for the power supply, wireless mouse, and misc cables, much less a bottle a water for the 4-hour plane trips.
On top of that, the charging port on my phone doesn't work anymore (I know, I need to change it, but I'm waiting for summer when I'm out of contract and can switch carriers and phones), but it still charges via the USB sync cable.
So the slim travel charger was looking pretty good - less space used in a very tight bag, and a way to charge my phone when my laptop is off. So I ordered it excitedly.
And I was quite let down.
The first issue I've had with it, is that although the transformer block it is slimmer in height that the one the that came with my laptop, it's just as long, and wider. At it's tallest, around the AC-in port, where it bulges out, it looks be just under a 1/4-inch in height savings. while being about 3/8th-inch wider and 1/8th-inch shorter (the long axis).
I have HP DV5Z-1000 laptop. The other day my AC adapter stopped working and won't charge my laptop. I know it is the adapter because when I have it plugged into the wall, and not even plugged into the laptop, it beeps.
I got my laptop in the US, but I am currently living in a small town in Canada and can't easily get replacement parts. I am not sure if HP will ship the same adapter to Canada.
My question is, can I buy any old adapter or would I need the same one it came with? If I need to buy a third party adapter what one can i get?
I got to admit that I got this Laptop for quite a while now but it is still bothering me that it reboots automatically after shutdown when power cord is plugged in. Without the power cord it works as it should.....
View 8 Replies View RelatedI have a Dell Inspiron 1520 and my friend has a Latitude D820.
Tonight she accidentally plugged my power adapter into her laptop. A few hours later, she noticed that her laptop indicated that it wasn't plugged in, and that's when we realized that she had accidentally used my adapter instead of hers.
Now my adapter doesn't work at all. We've tried the adapter with both our laptops with different outlets with the same problem, so we know it's the adapter. The green light also doesn't come on when it's plugged in anymore.
Did plugging my adapter into her laptop somehow screw up my adapter, or could this just be a coincidence? Is there any way to fix the adapter or at least figure out what the problem is? And if I have to purchase a new adapter, do the universal ones they sell at retail electronics stores work OK? I would order one from Dell but I'm working on a project now and I don't have time to wait for it to ship.
I have an Acer Aspire 7740-6656 that shows no signs of life. I have tried removing and replacing the battery as well as trying different locations to plug into power. I have even tried removing battery and power supply and holding start buttom 30 seconds. Except for a green light on the power supply cord, still no signs of life. What if any are my options?
View 3 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.

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.
I have just installed an i7 2670Qm on my T420 today.The machine will crash pretty soon after booting up, with the screen having colorful vertical and horizontal lines before it restarts itself and give the memory error beeping pattern (1 beep-pause-3 beeps-3 beeps-pause-1 beep).So then I took out one RAM from the bottom, and the machine appears to work normally again, more or less.
In the OS (Win7 64), The power manager alerts me that the 65w AC adapter is giving not enough power, so the laptop is running on battery. I thought I just need a 90W AC brick so the laptop will work as it should, so I am arranging a 90w one to come in later. But on a second thought, if the battery cannot start the laptop with 8GB of RAM properly.
Is it the CPU or RAM or Mobo or something else? Where should I look?The machine works fine with the previous CPU i3-2310m and 8GB of RAM.The RAM modules I have are 2 x 4GB Samsung 2Rx8 PC3-12800S-11-11-F3.The BIOS version is updated to the latest 1.46.
Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.

They blinked for about 2-3 seconds and stopped.

View 5 Replies View RelatedI recently received my Hp dv4t. Its cool but has below mentioned problems.
1) Wireless connectivity disappears after 1 min. I have to manually restart network connection.
2) CPU fan always remains on. HP has by default set it to "always on" in BIOS. I know they had some issues earlier with heating so as work around they introduced this Hack. Is same issue with this laptop too?
3) HDD is getting very hot. Much hotter compared to my dell studio laptop. Is this normal or shall I ask for some specific manufacturer harddisk in replacement?
4) display is not fitting in screen. Display leaves 4cm space on bottom and right edge. Is there any way to manually adjust display like the one monitor or other laptop manufacturers provide? I have asked for replacement of whole laptop at present
