Hi herbal-lee, goto www.ecs.com.tw and get your hands on the manual. on page 84 there is instructions on how to open the laptop. you need to remove the panel above the keyboard with the speakers. then there is a few more screws that will let you remove the keyboard and get the the guts. after you go that far there as little plastic clips around were the panels join that will need long finger nails or a fine blade/tools to unclip.
but if you are having a problem with battery charging/power it is most likely the battery at fault. most lithium ion batteries contain controllers that burn out or thermal fuses that blow if the cells gets too hot (stops the cells exploding and injuring people). you can test for both of these battery faults by connecting a voltmeter and testing for a voltage (12-18v)

Alright so you need to pull all of the screws out on the bottom of the laptop. The casing will most likely require a little force due to any sealant that the company used if this is the first time opening it. you may also notice a little locktight on the screws that you have pulled out. You just need to run your fingernail or a flatheaded screwdriver around the edge of the panel and pry it off little by little.
Let me know if you need further directions or have other questions and I would be glad to do what I can.
No! the power button is the last thing you would expect to go. Remove main battery and try again, if no! sub out the ram one at a time and test each one by attempting to power up, if still no result! the DC jack in the laptop is a trouble spot, at this point dis-assembly down to the motherboard is required, check DC jack connections carefully and resolder anyway, "board is double foiled"
Laptops do have a fuse near the DC power jack but it is soldered on to the board so it can't be changed. More likely than that you have a bad power jack. If your symptoms were intermittent charging or powering which got worse with time or if you wiggled the power cord you might get a connection it is probably the DC jack. These are repairable but require dis-assembly and some light soldering. If you are uncomfortable attempting that a shop usually charges about $80 to do it. To try it yourself download a service manual for your model, purchase the part (about $10), and give it a try.
Just to be on the safe side remove the main battery from the laptop since it is dead, in 50% of cases the laptop will run again. If there is no change the DC jack in the computer is the next likely suspect, most jacks that come loose can be resolded back on the motherboard but this no easy task. I usually go to www.ebay.com type laptop, make and model, and jack or DC jack, if you still want new. The laptop will require major dis-assembly and soldering work so if you attempt this be very careful and take your time.
The most common cause of this is the input jack being broken off of the mother board. There is a fair amount of stress on the jack which is surface mounted onto the motherboard. It is common for the connection to break off. This can be fixed easily by anyone that works on surface mounted equipment. Please note that the laptop will need to be dis-assembled to gain access to the area that needs repair. This is a fairly involved process and should not be attempted by someone not familiar with laptops. Expect to pay around $100 for this repair. No parts should be required.
Most likely the power jack inside the laptop has broken away from the PC board. This is a relatively simple repair once you get to the jack itself. The entire laptop needs to be dis-assembled to get to it though. I would not recommend any attempt to repair this unless you have experience with laptop dis-assembly/re-assembly. When I get this type of repair, I usually charge an $100 flat fee that includes the hardware repair as well as a systems check/cleaning.
It can be fixed but it means removing the original power socket and replacing it with a new one. The socket is usually soldered to the motherboard so the whole laptop has to be dismantled. Most people wouldnt even attempt to repair it and would probably change the motherboard. The socket is available here: http://www.computercare.ca/product.php?productid=16269 If you can find someone to do the job.
if u have already checked the adapter then make a power drag trial,
that is use the adapter with any other laptop of same voltage rating
and if the lap works there is no problem with adapter as some
adapters fail to deliver power at the time of consumption and gives
correct multimeter reading.If the problem is with ur laptop surely u
have to open the case,there after chk for dry solder and then chk power
regulator ics ,chk short circuit of components etc
