You need to remove the screws on the bottom of the laptop. Once the right screws are removed the case will seperate exposing the MOBO and that and you should see the dc jack (power jack) as forwarning, almost ALL dc jacks are sodered to the motherboard..and not easy to successfully replace.

I have no clue how to describe my problem.


If a tech opens the case, you're not going to lose your warranty, even if you do it. It sounds like the plastic container that you plug your power supply into has either broken around the outside or has come lose. If usually fits between both pieces of the case, so you have to open it to put it back in place.

My Asus Laptop won't turn back on, there is a chemical smell, and my adaptor green light brinks


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the Acer Aspire 5920 ac adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

No ac or battery power


Here are the possibilities from start to finish

A. The outlet you are using is bad try another outlet.

B. The wire going from the outlet to the adapter box is defective (you may have a light on your adapter so if it is on the you know that this isn't the case).

C. The Power Adapter Circuitry or fuse has gone defective. This is NOT recommended opening up and troubleshooting!! SMPS crammed into a little box are DANGEROUS !!!

D. The cable going from the power adapter circuitry housing to the computer ends connector is defective. You can test the power adapter output voltage at the connector end if you know what your doing with a multimeter, otherwise also not advised to do!!

E. The connector on your power adapter assembly has gone defective and no longer mates properly with the female power jack on your computer.

F. The power jack on the computer may be damaged and no longer mates with the Male power adapter end.

G. The power jack on the computer's solder connections on the motherboard have become damaged.

H. The power jacks cable going to the motherboard is defective.

I. The motherboard has been damaged by any of the above conditions.



There you go 9 possibilities. All in all; get a new power adapter that matches Voltage and Current Requirements printed on the sticker underneath your laptop. If that doesn't work, then you would have to open up your laptop and get real technical with your power jack and motherboard.

Broken power plugin port


The power plug in port you refer to is the DC Power Jack.

The AC adapter (Charger) converts AC electricity into DC electricity.
DC electricity has two poles. Positive, and Negative.
(Just like on a D cell flashlight battery)

The center pin of the DC Power Jack is the Positive connection.
The outer metal spring-like pieces, on the inside of the cylindrical shape surrounding the center pin, are the Negative connection.
(The pieces of spring-like metal, all connect to the Negative connection in the DC Power Jack)

Example of a replacement DC Power Jack, for the Asus Eee PC 1005HA Netbook,

[ Note*
Cannot agree with the replacement instructions they offer, at the bottom of the page.
Not everyone has access to a hot-air gun. A 25 Watt soldering iron, and Desoldering Braid, is better, and more easily accessed ]

A few articles dealing with replacement of a DC Power Jack,

http://www.laptoprepair101.com/laptop/2006/05/27/failed-laptop-power-jack-workaround/

1) Remove ALL power. Remove the AC adapter, (Charger), and Battery.
2) Observe Anti-Static Precautions. Buy, and use an ESD wrist strap.
Electro Static Discharge.

(Average cost is from $3 to $6. Connect the alligator clip to a good ground source.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.

Will not power up, tried switching batt and a/c adpt. Like the on/off button does not work


You may have a problem with the input power jack. The jack itself maybe open and does not provide power to charge the battery or power the computer. The laptop must be disassembled to check and/or repair the jack. Try getting the battery charged from another similar laptop and then see if the laptop powers up - if it does, the problem is the jack. Worst case is a bad motherboard.

No light when charger connected to laptop.


You do not have to resolder the connection, the dc jack is attached to the motherboard via a cable and plug. You can purchase these on Ebay for under 20 bucks. Below is the link to the disassebly guide that will assist you.

This link here is for the DC jack...

Laptop won't power on, suspect bad power port, is it better to replace just the power port or the whole motherboard? How hard is it to replace the whole motherboard?


Depends on the machine. In some case, the dc jack is easy to replace. IN other cases, you need to do soldering.

It takes about an hour to open an average laptop for the first time. When you get down the motherboard and jack. If the jack has power lines coming from it, you should be able to replace the jack for about $30.

If it is directly on the motherboard, you will need to solder. I would suggest a pro to do the soldering. That will cost you about $100 to $150.

You don't need to bother with the motherboard. It will cost more than an new computer.
