area 51 m 7700 shuts down

theres only a small posibility that the PSU is the cause of your problem, on the m7700 there far more inssues with heat on the CPU and video card causing teh computer to shutdown.

why would you put a bigger power supply on a computer that doesnt needs it??? besides the fact that you will have to complete modified the new power supply,
The original 220W is more than enough for that computer. dont you think there will be bigger problems if the ac adapter didnt had enough juice to power teh computer there will be far more people complaining.

you are giving us any good information your computer is shutting down??? so what??? you have a 1kw PSU on your desktop ?? and......

you need to give us more information is it shutting down on games? while playing DVD's? or what????

check the fan vents make sure they are complete clean, download the latest Bios update it will allow you to press FN+F2 to turn on the CPU fans at full speed in case the problem is overheating....

No joke, more info so we can help.

I have a Sager 9860, same model as the Alienware 7700. This line of laptops turned out to be lemons. My machine also shuts down randomly when gaming, surfing, or even when I look at it funny. Often to boot it back up, I have to apply pressure to the left bottom of the machine.

Yes, it is likely a power issue, but it would be the motherboard of the machine itself. I believe the only way to fix it, is a motherboard replacement. I REALLY hope your 7700 is still under warranty.

It is most likely your video card overheating. The 7700 series are plagued with heating problems. Alienware tech support is too stupid or lazy to diagnose it if you call in.

What you are describing is exactly what happened to me. You likely have the D05 revision of the mobo. It's a POS. You could try the bios upgrades if you haven't done that. As someone mentioned already, keep the vents clean - they suck the dust up very quick and get plugged.

See if you can find Getthermal - it will let you monitor the vid card & cpu temperatures. I noticed the version i have is a little buggy so you may want to find a current version or a different utility - check the downloads section & search the board.

If the vid card (R and L) gets over 70 Celcius, that is not too good. If it gets to 80+, that is REALLY BAD, m'kay? The vid card in my machine straight from Alienware would reach 127C and then shut down in the middle of the game(s).

When it does shut down on you, place your hands on the notebook keyboard normally. Wherever your left wrist touches the board you will notice it is blistering hot. That's your vid card.

I have the D06 revision of the mobo now (swapped it myself - not a task for everyone!!) and it runs better now. It will actually turn the fan on/up & stuff. My vid card now hovers between 55 and 60C during all use.

Yes, the revision number is under the sticks.

Mind also had random shutdowns. Cleaned fans regularly. As it turned out just blowing compressed air through fans is not enough. I had to remove Vid card and remove fan from there. The front of the fins on the heat sink were clogged with crap. Once I did a full cleaning, haven't had a shutdown since.

Confirmed: You should be able to see the mobo model/revision if you gently tilt the keyboard forward. The kb is attached to the mobo with a plastic ribbon cable near the space bar. If you pivot it on the edge closest to the spacebar, you should be able to peer down & see all or part of the model/revision # without pulling anytyhing out.

You should be able to see it right where the ribbon cables to the mobo. There should be a string of characters like this:
71-D90T0-D05 (*** bad news ***)
or
71-D90T0-D06


Again, if you try this, BE GENTLE.

To be safe, do this with the power off and the battery removed and yourself grounded. Even so, you could fry your equipment so do this at your own risk.

No, there's no POS replacement psu for your POS laptop. It's likely your POS cpu or your POS gpu is overheating, the POS. You can buy another POS ac adapter in either a POS 180W version, or a POS 220W version, but since they're POS parts, you may not want to buy one for your POS girlfriend.

Common POS problems for the POS Clevo d900's is the POS cpu overheating, the POS gpu overheating, or the POS motherboard going bad.

Next time, check the "no POS" checkbox on the configurator.

Factory clevo's come with heatpads, not thermal paste. AS5 or ceramique is a good bet for a solution if your problem is an overheating cpu or gpu, unless their already damaged by heat.

AW uses a thermal paste called DOW CORNING on the GPU and CPU of the m7700 this is actually better than AS5 on this computer, if you are still under warranty call TS they will send you some DOW CORNING at no charge.

i have done some testing comparing AS5 and dow corning and its actually better by 5 to 10 degrees

In any case, your laptop was really built by Clevo. Alienware just added $2000 U.S. for the stupid alien head and horrible "customer service".

If your machine is fried & you wanna get it going, I'd be happy to help since I've had my hands inside the 7700's guts already.
