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.

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.

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.

Acer 9100 dc jack broken


search ebay for a DC Jack for your model. Disassemble your laptop. Desolder the broken DC Jack from the laptop motherboard. Solder the new DC jack onto the motherboard and reassemble laptop. If your not experienced in soldering of disassembling laptops I would recommend you hire someone to do this job. If you wish contact me jason@jrdtech.net

Acer DC Power Jack


well..actually, it's installed on the motherboard..you'd need to strip the whole unit open, and then figure out how to desolder it from both top and bottom layers of the board..loads of potential issues arise on that.
