Aspire 1640z motherboard problem

hi there every one, your help is much appreciated...

i have an acer aspire 1642nlci laptop for about over 2 years now... recently the battery (simplo 4-cell) went nuts, and i disassembled it to see if i could do something about it ( the issue was, whenever i'd boot up my operating system i.e XP, the system would stuck, until i remove and then replug the battery in to the laptop)... well i did no repairing, just put the cells out and then back to the casing, inserted the battery into the lappy, and the issue went all by itself... however, 2,3 days later, the battery stopped charging and agonized by the situation already, and while i had my battery(without the casing) inserted into the laptop, i shorted the i/o pins of the battery to each others with a metal... and then the real issue began... my laptop is cursed, it won't start anymore past the initial 'acer' screen... sometimes the lcd won't light up even... pressing f2 helps nothing, keyboard doesn't work... and if you let it stay on for a while, the power indicator leds *both the supply and battery status ones* start to go dim and dimmer... i think i have fried the mother board's power supply area...

guys,,, i feel real trash for doing what i did,,, i have no idea what could be done to repair and undo the curse on my system... please advise...

thankyou !

 

Ok lets start with simple steps .

No 1 .... Does the laptop works well with out the battery ?

 

no it won't work no matter what... battery inserted or not...

 

No2 : Does the power button look alive ... gets green if you press it ?

 

yes it does...

 

No3 : If pressed , what laptop do ? mechanical sounds .. screen gets power?

 

the screen gets the power... but theres is one notable difference from the past, i.e, it glows very slowly to full brightness... another thing is, initially (after powering the system on) the supply led turns orange, then goes off, then the battery led turns orange (while the power supply led is off) and then the power supply led turns green for a while then keeps switching to orange/green back and forth, until both the leds dim out....

 

and no mechanical sounds !

 

Ok ..

Battery is dead , the electronic board in it , has decide , that this cells are in bad condition.

Now about the rest .
Yes the motherboards power circuitry, has got damaged.

Small damage for my size as technician , but it will drive you to send the laptop to Acer or elsewhere , for repair .

Forget this battery , and move on .

 

hell with the battery anyway... actually could you assist me as to the location of the power circuitry on the mother board a... what what component could have gone wrong... here is a jpeg of the affected region i found over the internet (the image shows the battery connections on the motherboard)

 

I am sorry my friend , I do not offer such services on the net .

 

hmmm... will it be too much to ask, if you are certain you could see that a certain component is faulty in the diagram i sent you (without telling me the component...)... just want to know, and be sure that theres an element that could be diagnosed to by faulty for sure...

 

Sorry my friend , but the picture that you had take with your mobile phone ,
does not help me , even for that.

Plus , if I do a diagnosis , I use tools for it , not pictures.

 

i would like to thank you for your time... however, the status quo prevails ironically !

 

I did not understand , you last message.

But any way , there is also more forum members here, its possible to get better services , if you wait around .

No hard feelings friend .

 

i meant thank you for trying and helping me out... i still look forward for guidance from other members on the matter !
