Alienware 18 AC disconnect/connect

Hey there NBR,

Anyone who can help me with this one ?
My AW always keeps disconnecting and reconnect and after a minute my screen freezes and i need to do a hard shutdown to get it to restart again.. im going crazy :/

When i put the battery out it works perfectly no shutdowns or strange behavoir.

Anyone with ideas or solutions
Thanks in advance

Specs
I7 4800mq
32 gig 1866mhz
980M Sli
330W adapter

 

Ask for a replacement power supply ... Same thing happen to my AW 18.

 

if it was the power supply wouldn't i have a shutdown when battery is out ?

 

Mine was the opposite of your issue. When i plug the ac , my screen dims , and cpu throttle ... it's weird.

 

im so frustrated right now i wanna throw this damn laptop on the terrace outside im so done with alienware systems NEVER AGAIN I PROMISE !

i will record this video and send it to alienware !!

 

My M18X R1 did the same thing. I just left the battery out. I am doing the same with my A18 as well. I dont need a battery. I use it as a desktop.

 

Cant play games on adapter only. you will lose so many power by the gpu's..

I bought 2 x 980m,s to play with not to look at it

 

Shutdown on games & benchmarks


battery freaks & flips out on battery only ! freezes and screen dimming all the time

 

I still think you have a bad AC adapter. If removing the battery creates more issues that further suggests the AC adapter is no good. Having the battery installed should be irrelevant and the behavior noted in the videos further suggests the AC adapter is failing. I do not recommend continuing to use it, as there is a remote chance it could be harmful. It could also have a problem with the socket the AC adapter plugs into on the left rear corner.

 

You can play games with just AC without battery if your PSU is working 100%.

 

No it works like a charm with only AC Adapter no problems.

AC Adapter only = Perfect
AC adapter + battery = bad
Battery only = SUPER BAD

 

OK, well then the battery is probably messed up. If it has a short internally it can damage the laptop or the AC adapter. It almost has to be one or the other. Since it works fine with AC adapter only, take the battery out or unplug it until you can get it replaced so nothing bad happens. If the machine is under warranty it may be covered. Battery wear is not covered under warranty, but defects like an internal short might be. Maybe Brother @Alienware-L_Porras can provide some direction on this.

 

Yea its in the freezer right now (Y)

 

Just wondering, do you use desktop mode battery charge? My laptop would disconnect the AC adapter if i use it and starts running on battery.

 

Are you sure that is not DC jack ? I have the same things with secondhand Alienware m18x R2 and i just resolder it.

 

ive tried both Enable and Disable option but nothing fixxed my problem i just had a bad battery.
ive put my battery in the freezer and see if that helps any

 

no im running right now only on AC Adapter and no battery and it runs like a charm right now i can overclock my gpu's more and stable without battery then with battery..

 

Yes that mean its not ac, mauby good to twst yoyr battery ? Mauny some kind of resistance ?

i have no idea what your saying

 

I had same problem while my AW was still covered by warranty. The replaced PSU (didnt help) then motherboard (didnt help) then finaly the battery and problem was gone.

 

Haha Its funny 90 % they always assume its the motherboard.

They are idiots !

 

You can try flexing your unit with the battery in and powered on to see if it triggers the issue each time. If it has a bad contact that continuously barely taps the receiver, you can experience these explained lock ups. Its unfortunately pretty common in 17.3 gaming laptops that get moved around frequently. If it does in fact turn out to be that, the hard part is figuring out if its your battery or contacts coming from the mobo.

 

Flexing in an Alienware 18 (or M18xR1, M18xR2, or M17xR2) chassis is non-existent. They don't have any flex because they are made of metal and extremely rigid. The Alienware 18 battery is connected by a wire that plugs into a socket. It does not have contacts like most laptops.
