20 Most Recent Gateway NV7915u Notebook Questions & Answers

I have yet to see a laptop that plugs directly into the mains - they mostly use an inline power supply to reduce the voltage, usually between 12 volts and about 20 volts and this is the highest voltage the actual computer needs. The screen might need more but that will be generated internally. A particularly sensitive person can feel voltages as low as 20 but most folk need around 40 volts before it can be felt. The power light is an led requiring a voltage of between 0.8 and possibly as much as 2.8. In theory it would be impossible for you to receive an electric shock from your laptop and even if the power supply had become leaky which could make metal components "live", the light and the surrounding material is made of insulating plastic material. If the laptop is running on the battery this possibility is eliminated. You can check for the presence of shock-level voltage there by using a neon mains tested screwdriver or an analogue multimeter with the black probe connected to ground. If no voltage is found to be leaking around the light the answer might be a static discharge...

It could be over heating. Try vacuuming the vents of the fan. There are vents air is sucked into the fan and exhaust vents that the fan blows the air over coils that heat the air. The coils get dirty. The next step for overheating is taking apart the notebook and applying new thermal paste. Taking apart a laptop is very involved.

Try removing your battery and power on your computer with your power cord only. If you have no problem with the power cord alone, then you need to replace the battery. I hope this helps!David

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

Disassembly? Same as the NV78 Series,http://www.insidemylaptop.com/disassemble-gateway-nv7802u-laptop/The Ram Memory is on the bottom of the motherboard. So is the Processor. (CPU)You have to disassemble from the Keyboard down, and remove the Motherboard.1) Remove ALL power. Remove the AC adapter (Charger), and Battery.2) Work on a table. Do Not work on a bed, couch, or directly on a carpet floor. HIGH areas of -> Static electricity.Suggest lay a soft Static free cloth on the table you're working on.Helps prevent scratching the laptop, and the table.Laptop closed, turn it over, lay it bottom side up on the table.3) Don your ESD wrist strap.Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.Wear an ESD wrist strap, and have it's alligator clip attached to a good ground source, and your laptop is safe.Don't wear an ESD wrist strap, and you can use your motherboard for a Frisbee. (Processor for a neck fob, ram memory for Christmas decorations)Average cost is around $3 to $6. Here is but one example,http://www.radioshack.com/product/index.jsp?productId=21032454) Remove the Harddrive Compartment Cover, and Memory Compartment Cover.A) Remove the Ram Memory. Ease the Spring Clips out a little bit to unlock the Ram Memory module/s. The Ram Memory module will slightly spring up at an angle. REMOVE ram memory module AT that angle.If you lift straight up you will damage the contact pins in the Ram Memory slot.[To reinstall, Ram Memory module goes back in at THAT angle. Once assured it is seated well in the Ram Memory slot; push it down to lock it in the spring clips ]B) Remove the Harddrive.The Harddrive is inside a metal Harddrive Caddy. A sheet metal enclosure. Remove the Harddrive with the Harddrive Caddy.Remove any screws holding the Harddrive Caddy in, grasp the Mylar strip, pull the Harddrive towards the outside of the laptop, and unplug it. Lift up at an angle, lifting on Mylar strip side, and remove.5) Remove the single Philips head screw holding the DVD drive in place, remove the DVD drive.(No.1 Philips screwdriver, or equivalent Jewelers screwdriver)6) Remove the 3 Philips head screws down in the Battery Compartment.Turn the laptop over to it's normal position, open it up.Remove the Keyboard Cover (Gateway terminology. In pictorial disassembly it is called the LED Board Cover)When removing, BE AWARE that there is a Multimedia Cable still attached to the Multimedia Board. (Multimedia Board is attached to the bottom of the Keyboard Cover)Gently pop the Keyboard Cover loose. I DO NOT recommend using a metal tool! Use a thick guitar pick to start, ease off with fingertips; OR use a Spudger Tool,http://www.amazon.com/Techni-Tool-Spudger-Alignment-Tool-Black/dp/B000PDNPYKhttp://www.wisegeek.com/what-is-a-spudger.htmThe Multimedia Board in the Keyboard Cover, has a cable just like a Keyboard Cable. It is an FFC. Flat Flex Cable.One example,http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpgAs you can see, there is NO plug connector on the end of the cable.The FFC slides into a motherboard connector, that is a style of ZIF connector. Zero Insertion Force.Slides into the BODY of the motherboard connector, and is locked in place by a Wedge design. The Locking Bar wedges against it.The Multimedia Board Cable's flat bar terminal strips, line up with contact pins on the motherboard connector.The Multimedia Board Cable MUST go back in the same position, as it was when originally installed.Even if it's twisted, flopped over, or going to Hawaii for vacation(?).For this reason, you may wish to make a mark on one side of the cable, and a matching mark on the same side of the motherboard's connector. (Sharpee?)Do the same for the Keyboard Cable, and all flat flex cables if you wish.IF, the motherboard connector is broken for the Multimedia Board Cable, or Keyboard Cable, or Touchpad Cable, or any flat flex cable; your are looking at MOTHERBOARD REPLACEMENT, and why I am being so detailed.The Multimedia Board Cable's motherboard connector, is supposed to be what I deem, the Flip-Up style.This is a better illustration of how to open that connector,Flip-Up style:Closed/Locked,http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-13.jpgOpen/Unlocked,http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-14.jpgUse the Mylar tape on the Multimedia Board Cable, to remove it from the motherboard connector after unlocked.Lay the Keyboard Cover aside.7) Remove the Keyboard:The Keyboard has TABS on your side. They slide under the Palm Rest Cover. Lift the Keyboard at a slight angle on the LCD screen side, slide it towards the LCD screen JUST a little.Lift the Keyboard on the LCD screen side, roll it over towards you, lay on the Palm Rest Cover.Disconnect the Keyboard Cable from the motherboard connector.Shows it to be what I deem the Sliding style.Here is another example of that style of motherboard connector, only in more detail,Sliding type:Closed/Locked,http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L675D-L670D/big-body/dismantle-laptop-10.jpgOpen/Unlocked,http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L675D-L670D/big-body/dismantle-laptop-11.jpgAs you can see, in the Locked position all you see are two 'Tabs' of the sliding Locking Bar.Use your Thumbnails to GENTLY ease it open. Using a metal tool is DU-MB. One slip, and you break the motherboard connector, or stab the motherboard.The Locking Bar only moves about 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital letter -> O <-8) Close the laptop, turn it over. Remove the Wireless Module.There are two Wireless Antenna wires. One Black, one White.Make a note as to WHICH terminals on the Wireless Module, that they go to. [Black to Main {1} White to Aux {2} ]The Wireless Antenna wire's connector clip, slides off to remove.Remove the Philips head screw which holds the Wireless Module in place, remove the Wireless Module. Makes it MUCH easier to access the Wireless Antenna wires.The Wireless Antenna wires STAY with the Display Assembly.They go up into the Display Assembly, and are connected to the Wireless Antenna.The Wireless Antenna wires are threaded, ('fished') up through the cavity hole in the laptop; and laid to the right side out of the way.(Gently pull one wire from the top with one hand, while easing the wire up from the bottom with the other hand)The Wireless Antenna wires go through CHANNELS and LATCHES.They MUST be reinstalled in the same routing as they were originally! Failure to do so, will NOT let the laptop close properly when reassembling, and MAY cause damage to the wires! (Pinched/Broken)You can lay the laptop on it's side to ease facilitation of removal.Fish the Wireless Antenna wires up, and out.More in a Comment.Regards, joecoolvette

follow this link;http://www.tech-faq.com/reset-bios-password.htmland next time a word to the wise, don't let anyone near your computer. and next time you see that guy, i'd tell him you had to pay $100 to get it fixed and charge himthat might have been funny at the time, but really isn't

download and install speedfan, you will be able to check your CPU temp. if it's not too hot, then it might be a power issue. Have you tried removing the battery for 30 mins, then trying it ?Tallon41

this is the hardware vendor detecting software http://global-download.gateway.com/FilesDownload/HWID/HWVendorDetection.exeif that doesn't help (which i think is what you're saying) try the chipset driver, it may have the correct driver in there. If you need further help, reach me via phone at https://www.6ya.com/expert/joel_63c670a84e9f6a97

The error PXE-E61: Media test failure usually means the hard diskhas failed or the hard disk needs re-seating or the disk controller is faulty.First - re-seat the harddisk and reboot the computer. If the computer does not boot up then reboot andgo into the BIOS configuration to see if the BIOS detects the hard drive. If itdoesn't detect the hard drive then it could be faulty.Next - to check if the harddrive is faulty, remove the hard drive and insert it into an USB hard drive adapter and connect it to a workingcomputer's USB port. If this computer cannot see itas an USB mass storage device and you cannot open the various folders and fileson this drive, then this confirms the hard drive is faulty.Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.

Below are links to three versions of the driver for the NV79's wireless LAN. Which is the correct one will depend on the manufacturer of your notebook's on-board wireless card. For simplicity sake, I recommend just downloading and installing all three; your computer will be able to determine which is the correct one.

Here are the links:
Intel: Download
Atheros: Download
Realtek: Download

Each of these links was obtained from Gateway's official driver download web site for the NV79 Series notebook computer (which you can access here).

Hi Michael,

Kernel Power - Error Code 41 often times caused by conflicting drivers. If you are trying to play a game or watching videos then the computer suddenly turns off, you must first check the following:

1. Open Device Manager (click Start > type Device Manager) and go to Sound, Video, and Game Controllers and see you have two audio drivers installed and disable one at a time and see if it fixes the issue.

2. Boot into Safe mode (press F8 continuously upon boot up) and see if the computer still shuts down there. (If it doesn't try disabling start-up items using this guide

3. If you're pop-up error messages like "System services cannot be started" upon boot-up, you're operating system is corrupted and must be restored to default settings. (you need to press F11 upon boot up - remember to backup your important files)

3. If Step 2 above is true, check if the computer is overheating. If it does, the computer needs to be serviced. Contact gateway support at 1-800-846-2000.


Cheers.

your fan is not work properly that the only problem.
you see its ok because. its working but the fan is already weak.. the air of the fan is not the same
in its brandnew. it already weak the to find a good condistion fan.

When the CPU overheats it goes into thermal shutdown and will not boot up again until it has cooled down.
The heat sink may be clogged with dust and causes the CPU to overheat by reducing air circulation over the heatsink.
If you are not using your laptop on a flat surface, it may beobstructing the cooling vents on the bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem

It is located at the actual hinge on the right side.
Hope this helps :)
