Dell :: D-series AC Adapter And E6400
Sep 27, 2008
I looking to buy a new Latitude E-series but I have one worry. During the years with D-series I have built up a "infrastructure" of AC adapters in my home, car and my offices so I dont have to carry around these bricks. My wife and kids use them too since we all have compatible Dells. Very convenient indeed.
Looking at the specs for the E-series adapter it uses the same voltage as the D-series (19.5V) and the power tip looks the same(?). So, can it be so wonderful that the E-series can use the D-series adapter? I don't want to shell out money on 4-5 new adapters...

I just received my e6400, and it is now charging the battery. The ac power adapter is very very hot, is that normal? Should I ask them to change one for me?

Love the NB, but hate the AC. Why it came with 3-prong AC while most NB comes with 2-prong AC? Is there anyway to convert?

I've seen discussions at length on here about wanting 2.5" Media Bay's for E6400, and I've since seen lots of solutions for that. I have a 1.8" Intel X18-M and I am trying to locate the 1.8" media bay for the E640

The latest version of the Intel Intel Display Adapter Driver available on the Dell website is 6.14.10.4980 dated 08/25/2008..
The Intel website shows Version 6.14.10.5029 dated 01/21/2009 is available..
Has anyone updated their E6400 to this new driver? Does anyone know of any specific benefits or problems with this new driver?..

I have an AC adapter left over from my first generation X1 Carbon. It is 90W/20V. The adapter that came with the new machine is quite a bit smaller, and only 65W/20V. Can I use the 90 watt adapter with the new model X1, or will it damage it somehow? Dont want to ruin my brand new computer.

I just ordered a Dell Latitude E6500.
Now I'm looking to get a cable lock for it. I know they are not the best at protecting your laptop, but some protection is better than none, besides I just want to lock down to a table while I need to run to the bathroom for a minute.
So, from personal experience, if you have a Dell Latitude E6500/E6400, what locks work/fit best for it? I've done some research and I've tried to read around(couldn't find much on here for the specific laptop).
So far I'm looking at these two (but I have no word from latitude E6500/E6400 users): ..

Is there something similar to this [url]that will work in my DV2700?
The DVD drive it came with is garbage... and I usually burn on my desktop so I was wondering if there was a better use for the drive bay. Then again, im not sure its worth the hit on battery life when I can buy a 500gb.

I'm using a seconday (spare) power adapter at home, for my y50.  The adapter is a 20 volt / 90 watt unit.  My primary adapter (in work) is the original adapter that came with the Y50, a 20 volt / 120 watt unit.  When using the laptop with the spare adapter (the 90 watt unit) I get a Lenovo Energy Manager message that pops up stating "Adapter has limited support" and "Performance will be affected if the power adapter cannot provide enough charge".  Presumably the laptop would need more than 90 watts to drive it if the CPU and /or video were working hard?  Do you see any issues using that adapter for day to day work, that is, not gaming?  Also, can the messge be disabled?

I'm on a roll with my new y510p. Â Last night I got the unit new from Lenovo outlet, and the battery wont' charge past 33% (covered in another post) and now the wireless adapter isn't working.
Â
I can't connect or find any wireless networks, though I could last night. Â And the windows networking troubleshooter can't find anything. Â What's more, when I go to the command line and type 'ipconfig /all' nothing appears, no network adapters at all. Â
Â
I've rebooted several times and even tried the Intel wireless proset (believe that's what it's called) utility that comes with the laptop. It squawked on the hardware test-- something about not 'wireless hardware is not bound to transport driver'.

I am using ideapad y510p. My wifi worked perfectly yesterday evening. However today at morning I couldnt find any wifi networks. After some research I have discovered that there is not wifi adapter present in Network Adapters and also that there is no wifi adapter in device manager. However bluetooth works fine. I have tried reinstalling drivers (even clean install of everything that may have something with networking). But I still cant see any wifi adapter. LAN connection works just fine. I dont think this should be hardware related problem because as far as I know bluetooth and wifi adapters are both located on Intel Centrino N2230. So I think that if my wifi adapter would be broken than bluetooth wouldnt be working too. I have also tried using system restore point to last week (when everything was working perfectly) but it didnt work.
Â
I have also downloaded latest drivers from intel website and when I run tests with theirs WiFi Software Utility (or whatever it is called) it says that there is no wifi adapter present so it fails even hardware test.

New W540, bios 2.10, latest drivers installed, 20BH
Â
My w540 is not registering my Samsung 840 Pro SSD in the 9.5mm ultrabay adapter.
Â
Not showing in BIOS, and not showing in disk manager or in device manager anywhere. I just want to use it as a second drive.
Â
Main drive is 7200 rpm - with a Win 7 corporate image on it.

I 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.

My lenovo g570 laptop does not found network adapter for wifi and blue tooth it did not recognize the hardware part may be. because i install software for that so may time. few days back i used wifi as well as bluetooth in my lapi but for last two or three month i just used lan for internet connection and in between i changed my os which is win 7 ultimate to win 7 proff. I don't know what is the reason for that.

Month ago x200 works well. I leave it on table for a mont and do not use it at all. But now, x200 turns on only with inserted AC adapter charger. It does not turn on with only inserted battery (without AC adapter charger), just nothing happend when I press power button.
But battery charges and program "Thinkpad Power Manager" detects battery and it's charge. Battery is ok (tested on another X200 and works well).

I just got a W540 running Windows 7 x64 at work. Â I have an ExpressCard ethernet adapter (A Belkin f5u250), and I'm having trouble getting it working.
Â
I used this card on a W510 running Windows XP for years with no issues.  I can still plug it into that laptop and have it work just fine.  However, when I plug it into the W540, nothing happens.  Windows does nothing.  It doesn't act like it's trying to identify hardware, go find drivers, or anything.  Nothing shows up or changes in the device manager, either.
Â
I've tried doing the "add legacy hardware" thing in device manager, but I've had no luck with that, either. Â If I do an autodetect, it doesn't find anything, and if I manually browse to the driver, it then brings me to a list of devices, and the list is empty.
Â
Is there something special I need to do to enable the expresscard slot, or enable plug and play for it, or something?

I havea serious problem with my G510 i7 4700MQ.When i plug the power adapter the cpu frequency is set 798 Mhz.When i UNplug the power adapter i can reach maximum 2.4 Ghz.Obvisously i cannot get turbo 3.4Ghz at all.Graphics adapter frequency is also drops to 200 Mhz when i plug the power adapter. is it a buggy notebook? My bios version is 3.05 and i know that the newer version is 3.09 but bios update is only available in Windows 8. I've got windows 7 intel processor diagnostic tool shows FAILED when accessing cpu frequency.

This is not "battery pluged-in not charging" issue. That issue is software related and can be easily changed the option whether Life or Health of battery you concerned by LEM. I'm one of Y580 owner that facing that issue that the laptop cannot detect the AC adaptor anymore after performing the Battery Guage Reset".
For example: URL...I was tring to search for the solution, but as you know there is nothing without send it back to service center.The tempolary solution I was using is,
1. Remove the battery (if laptop is powering on, then shutdown it first).
2. Remove the AC adaptor from wall ac receptacle.
3. Once the laptop is completely powered down, plug AC adaptor to your laptop and wall AC receptacle.
4. After a few second, insert battery back into the Laptop. And then, the battery will be chaged as usaul.
5. You need to repeat step 1-4 above every time you unpluged the AC adaptor.
By the way, I have been living with that issue for almost 2 years, until it was already out of waranty in June 2014. So rightnow, I can do whatever I want without worrying the waranty. I was trying to teardown my Y580 to find the dead components. I gusted that the issue may be from charging circuit. Afetr opened the chassis, I found that the Y580 uses BQ24737 from TI to be the charging controller.
I cannot found the BQ24737's datasheet, but I was using BQ24735 instead, since, they have the same pinout with difference in optional functions. I found it. The dead one is the input MOSFET. It's shorted between Drain and Source!. That lets the voltage from AC adapter directly connected to Battery. And then, the AC adapter will be tripped with over current protection and the voltage is held to near zero. That's why we cannot plug the ac adapter with battery inserted for this case.
So far, after I replaced it with the similar rating MOSFET from old laptop, it works!. So, I can plug to charge my laptop as it should be without problem.the actual circuit shound not be exactly the same with datasheet. For the Y580, the input MOSFET (Q1 in datasheet and PQ302 in Y580) is P-Channel (AO4423), and it has the external circuitry to dive that MOSFET instead of U1. send it to service center to replace the new motherboard. If not, and you have electronic/soldring skill, you can do it by your self.
Tools needed,
1. Soldering iron (it will be easier for removing part from PCB, if you have 2 of them).
2. Equivalent electrical rating MOSFET.
3. Multimeter.
The different model, different location. Anyway, you can check whether it is the right MOSFET that need to be replace by,
1. Disconnect battrey from labtop
2. Using multumeter (ohm function) to measure the resistance between pin Drain and Source of the MOSFETs. The dead one must has very low D to S resistance (near 0Ohm) for both direction (D(+)<-->S(-) and D(-)<-->S(+)).
3. Search for the dead MOSFET's datasheet and then find/cross the new one from local supplier.
4. Just replace with the good one.

I have a 3444-CUU that I really love. When I first got it I realised the wireless adapter would just randomly stop working. I updated every possible driver and I'm still having the same issues. All I can do is reset the adapter to get it kicking again. I'm not sure if the wifi care is soldered or if it could be removed or replaced but I'm really leaning towards it being a hardware issue.
Â
It'll either stop working could turkey, won't detect any wireless networks or it'll stop working and I can still view other wireless networks but I cannot connect to them. Resetting the adapter is the only option. As I'm writing this right now the wireless has gone out again. So I have to reset the adapter for 5-10 more minutes of internet just so that I can post this.

I've got Dell Latitude C 640. I had to reinstall the operating system from recovery disks. All was smooth.
Now, when I'm trying to install a driver for the wireless adapter it asks me to remove the adapter first. I can't find it to remove it.

I'm seriously thinking of replacing my Go 7900 GS GPU with a Go 7900 GTX. (within some time because I don't have enough money right now (I'm only 14).
Now is my question, is my adapter going to be strong enough for the Go 7900 GTX? From other hardware, I have a T7400 (2,16 Ghz Core 2 duo) a seagate 7200.3 (Seagate says: "The Seagate® Momentus® 7200.3 laptop hard drive delivers industry-leading 7200-RPM performance while offering the industry’s lowest power consumption levels.") I have 4 GIG hyperx RAM.
And another question: where can I buy a Go 7900 GTX, I found some on EBay, but I don't like that way of buying things. Is there a direct way to buy one from Dell? I searched on their sitre but didn't find any link for spare part GPU's.
