Does the hard drive have to be in for the power to go on? NO

All you will get is the BIOS boot up screen then and error screen saying it can't detect hard drive.

Asus k53e won't turn on


That particular model Asus laptop are susceptible to over heating on the DC power jack and finally creating a short due to the shotty work on the board and or the possible shotty DC power jack. If you computer will not turn on and your battery is probably dead and even plugged in the power light does not come on? Then it is your DC Power Jack on the laptop. So the DC power jack for that model will run you between $0.48-$6 bucks. However if you are a soldiering guru then you can disassemble the laptop and remove and replace it. However, it is not cost effective to let a shop do it, because they will charge you way to much for the job. Honestly, it would be much cheaper and more efficient just to buy yourself another laptop. If you know someone who is savvy enough they can removed your hard drive from your laptop and pull off whatever data you want and move it onto your new laptop.

Compaq evo n1015v will not boot up when power is pressed


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:http://www.ifitjams.com/lappower.htm

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

Is not charging battery


If the laptop works with the AC Adapter Power Cord ok without any problems except the battery is not charging, then the battery is dead. Batteries only have a useful life, then they have to be replaced.

If the laptop does not work with the AC Adapter Power Cord then either the Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. If either of these is bad, a good battery will not charge.

Check your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

The orange charge light comes on but when I press to start computor nothing happens no green light, the orange light flickers a few times.....I have taken out hard drive and batteries afew time but nothing...


Charger faulty or Motherboard problem.
You can check the power supply of the charger by measuring the DC voltage at the DC jack with a multimeter set to DC volts (red probe on the inner of the jack, black probe on the outer of the jack, should measure 18-20 volts.

Also check the security of the jack in the DC port, make sure it is not loose

See if the Ac adaptor has a green led on it, flashing LED indicates power not being "used " by the laptop

Gut instinct with this being a compaq is that the fault lies in the motherboard

My hp compaq laptop charger is not working in the charging port but the laptop work's when the battery is charge and place in the laptop how to use the external battery port


First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

Tech manual for Asus Z96J lap top. need to replace the dc power jack how do I access the power jack?


For all the function and portability laptops provide, there are also some drawbacks. The biggest problem with laptops is with battery life. To get constant battery power, the laptop has to be plugged into a wall outlet. The wall plug then connects to the DC jack in the back of the laptop. The DC jack is no more than a little piece of metal that conducts the electricity for the computer. These DC jacks are known to be fragile and break off easily. If this happens, you can open the laptop and replace the DC jack yourself.
  1. Step 1 Remove the internal battery pack from your laptop. Flip the laptop over and locate the release button for the battery pack. Hold the button in to slide the battery pack free. It is important that you remove the internal battery pack as well as unplug the power cord from the wall outlet to prevent risk of shock while working inside the laptop.
  2. Step 2 Unscrew all of the screws on the underside of your laptop. The number of screws will depend on the model of computer. There should be one at each corner and then one or two screws that hold the hard drivemag-glass_10x10.gif cover in place. Once the screws are removed, take out your computer's hard drive. Newer-model computers will have a hard drive that slides out of the side of the computer.
  3. Step 3 Locate the two screws at the back of the computer that hold the laptop screen's hinges in place. Once these two screws are removed, gently pull up on the screen until you clear the silver pegs from the holes in the laptop's body. Two wires lead from the screen into the computer, so ensure you do not pull so hard that you disconnect them. Carefully set the laptop screen aside so it does not get damaged while you work inside the computer.
  4. Step 4 Separate the two halves of the laptop's body to expose the computer's internal components. Flip the keyboard on its face, making sure not to disconnect the keyboard's connector. Underneath the keyboard will be a metal plate that covers the computer's motherboard. Unscrew the screws that hold this plate in place and set it aside.
  5. Step 5 Locate the DC jack for the laptop. Most all laptop's DC jack outlets are located at the back left corner of the computer. Using your tweezers, remove the old DC jack. Identify the slot in the motherboard that the old DC jack came out of. If the DC jack was loose before you removed it, there will be a small slot at the base of the opening in the back of the computer that the DC jack pops into. Using the tweezers again, slide the new DC jack into this slot until you hear a clicking sound. To hold it in place you can solder the new jack to the motherboard, or simply superglue it in place. Don't use too much superglue or you will risk losing the ability for the jack to conduct electricity.

My hp compaq nc6400 doesn't turn on. the green


Laptop is dead. How to troubleshoot the problem.
In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.
Let’s take a look at two different scenarios.
Example 1. The laptop is absolutely dead.
When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.

What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.
3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.

OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule:
The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.

If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack.
Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start.
First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint.
If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations.
Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable.
In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory.
Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead.
If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots.

In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on.
Try removing battery, hard drive and DVD drive and turning on the laptop without these components.
Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel.
Finally, disassemble the laptop and removed the motherboard.
1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard
2. CPU with heatsink and cooling fan.
3. Known good memory module.
4. The power button board witch you need to turn on the system.
5. Working DC power adapter.

Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video.
At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard.

Latitude C640 is dead!!


The only solution that I can think of would be a power jack problem. I would not advise replacing the power jack yourself since you have to take out the laptop mother board, de-solder the power jack then solder the new one on and put it back together. My advice would be to take it to a professional computer repair shop and have them take a look at it and replace the power jack. It is worth getting repaired since power jacks usually range $40-$70.
