If these are the only symptoms, then chances are the problem is either (1) a bad battery that is no longer retaining a charge or (2) the charger is not charging either because it is bad or the plug on the laptop is broken (which is repairable but maybe costly due to labor cost (approx 1-1.5 hr task)). I presuming it is not under warranty.

If there are other symptoms, it would require testing to determine; not a task for a DIYer except if it's a bad battery or bad charger.

    If it comes on without the battery and stills shuts off after 2 min or so; you either have an overheating CPU (bad fan or other physical failure) or have a virus(s). Some viruses will act this way.

    Does it give some kind of error or just bluntly shut off?



    Let me know how this goes.

Can i do recorded from surveillance camera with this model? mx6448 gate way notebook?


Sure, you can use most computers as servers to record surveillance video if you have the right hardware and recording software. This would all depend on what brand of surveillance cameras you have and if they are analog or digital and if your video is coming in through your network or by other video capture hardware.

I have a gateway mx6448 laptop the power jack on motherboard has failed how do you test and can you get another one to solder in and where.. i know my cord is good i got 19.3 volts and says needs 19 volts....


Just to be on the safe side remove the main battery from the laptop since it is dead, in 50% of cases the laptop will run again. If there is no change the DC jack in the computer is the next likely suspect, most jacks that come loose can be resolded back on the motherboard but this no easy task. I usually go to www.ebay.com type laptop, make and model, and jack or DC jack, if you still want new. The laptop will require major dis-assembly and soldering work so if you attempt this be very careful and take your time.

No light, no up, nothings. power nothing please i need help. battery 100%


So the first thing to do is to plug it in so you can eliminate the battery as a potential problem, but if that does nothing, things are not so good.

If the laptop makes no sound at all, there are really only two pieces you can fix or replace, the HD and the RAM. The Ram is the easiest and will cost you about $20.

The manual to replace the ram is here:
http://support.gateway.com/s/Mobile/Q106/Blade/8511418.pdf

The ram itself is here:
http://www.memoryupgrade.pro/1gb-gateway-mx6448-memory-1x-1gb-qnd1smerzztae8-pc2-4200-ddr2-533mhz-so-dimm-upgrade.html

It is possible it is the hard drive which you can replace for about $40, but at that point, you may as well buy a new computer, because usually it is only your data you care about on a computer over 3 years old.

...you might also try unscrewing the case. It is possible, but unlikely, you have a simple wire break in the power button or a weak contact in that switch. It is unlikely, but possible.

Good luck.

MX6448 won't boot; black screen.


It seems that you don't remove the battery when you use the Notebook. This practice shortens the life of the battery because, when you use the a/c adapter and the battery, your battery is alternately charging and discharging all the time. The cells in the battery eventually die.

From what you describe, it sounds like the power strip inside the Notebook (where you plug in the adapter cord) has been damaged and needs to be replaced.

Your computer is not a total loss. Just have that power strip and the battery replaced and your Notebook should be up and running again.

And, in the future, if you just remove the battery when your kid uses the computer, or if you are going to be using it for over 1 hour. Save the battery to use when you need the mobility.

When the laptop is booting it just gets to the wallpaper and stop


Disconnect any devices (i.e. external keyboard, mouse, printer, cameras etc). Have just power attached. Shut down and reboot. What happens?

If still nothing .. get into the CMOS\BIOS/Setup

Reset CMOS/BIOS to defaults .. save and restart

The biggest removable door held on by about 6 screws on the bottom of your laptop is what you need to remove. Once inside you will see your heatsink! Very easy to access, I wish you luck.
