My computer does not start up looks like in satnd by mode


Most All-in-One Personal Computers (PCs) are based on internal laptop/notebook component technology.

The first item to test is the Alternating Current (AC)/ Direct Current (DC) Power Adapter to see if there is:

damage or a fault in the cabling;

damage or a fault in the transformer box;

a fault, damage or a loose connection in the AC/DC Adapter Jack point via which the AC/DC Adapter plugs into the PC.

If no AC/DC Adapter-related fault is evident or any such fault is definitively resolved (such as by testing a definitively functional replacement AC/DC Adapter), then his sounds like either a Loose AC/DC Power Jack detached from or short-circuiting its Motherboard Solder Points, a Power Management problem on the Power Management Tracks, Electrolytic Capacitors or Power Management Contoller Integrated Circuit (IC)/Chip on the Motherboard or a Graphics Chip or Graphics Card damaged surface or Motherboard Solder Point Contact fault.

Any of the 3 internal faults described above would require specialist internal diagnostics, repair and testing by a technician with specialist laptop repair experience and specialist Infra Red Workstation, BGA Reballing StationMicro-Soldering, Oscilloscope, and Multi-Metering equipment.

DC Jack repairs are likely to be moderately expensive. Power Management or Graphics repairs are likely to be more expensive still, but if conducted by a professional, all three repairs should resolve the problem. A competent repair technician should be able to repair these faults and offer a minimum 3 month warranty on a reoccurrence of the same fault.

So, on the symptoms described in the question, yes. Unless it is just an AC/DC Adapter fault, this will probably prove to be a serious, non-DIY repair problem, I'm afraid.

Audio cuts in and out in media center or while watching a dvd


Check to ensure that the speaker connection plug is fully inserted into the speaker jack on the computer. Do the same for the power connection at the speaker, too. Slightly wiggle or twist the connections and wires - one at a time to isolate the source of the failure (can be the power plug or wire, audio plug or wire, or even the jack on the PC . If related to the speaker plug, try using the speakers in another speaker jack on the PC - or other device (mp3 player, etc.) if the problem is still present on both locations, it is related to the speakers / power. Try using a pair of headphones plugged directly into the speaker jack on the PC to see if the problem is present still. If the problem is common to both speaker and headphones, the jack on the PC is likely the culprit, and a new sound card will probably have to be installed. Otherwise, replace / repair the speaker cable, plug or system.

The likely source of the problem is a stretched wire along the cord - or at the plug. A repair can be attempted if desired - or replace the speaker system if lacking tools or if unsure how to go about it.

Power jack connection broken on HP Omnibook xe3


The jack in itself is quite robust, it is the soldering to the board that sometimes lack substance, also rough usage in the way of forcing the plug in and pulling it out roughly contributes to the demise of the soldering. If the jack is still intact take it to a repair shop and if the pads haven't broken away from the printed cirsuit board have them reflow and maybe add a bit of extra solder to the joints.

Dead Toshiba A100 laptop computer


In order to replace the power jack in your laptop you’ll have to remove the jack from the motherboard as I explained in the previous post: Replacing DC power jack.
While removing the jack you can accidentally pull out the internal copper coating (I’ll call it a sleeve) from the inside of the “+” terminal as it shown on the picture below.
9807c6d.jpg
The internal copper sleeve has been removed and cannot be installed back. If you solder the power jack back on the motherboard without this sleeve it might work but the connection between the “+” lead and motherboard will not be reliable.
In the following guide I explain how to fortify a damaged power jack connection. You can use this repair technique in some laptops with similar power jacks.
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. Check out thisguide for fixing laptop power jack.

Power jack on Acer Aspire 5610 loose - how can I replace it?


The power jack on that model is soldered to the mainboard.

Unless you're comfortable with taking the notebook apart, and good with a soldering iron, it is best to take it to a shop.

If you choose to do this yourself, the power jacks can be bought from several sources for around $10 including shipping.

Repair shops charge $100-$150 to perform this repair.
