sorry for the delay, i was off from my forum for a long span, but i am back....u can change with 10v instead of 6.3v but keep the value same or higher.

Added after 3 minutes:

as far as i have to do its my regular job, if u want to do it may be waste to purchase a rom programmer which cost more then Rs. 10,000 plus.

hello

See as far as the display card is concerned, it is ok, because its giving display, but is not supporting colour in windows as if the driver is not loaded. The very first simple job you will do is take a scrabber and clean the contact points of the display card, i think the problem should be sorted out. clean both side of the cards the connector which goes to agp slot.

14 Oct 2009 21:39 Problem with ACER Aspire 5632

hello,

I have a laptop ACER Aspire 5632 which no longer loads the battery. I changed the battery and the same thing. Windows can clearly see the shift in the sector but does not load. If I leave the laptop on AC only without battery it does not start. Could you help me or tell me where is the diagram of the motherboard of this laptop.

Thank you

Hello

i'm new on this list and i hope you will understand my bad english Smile

I have a Packard Bell ALP-AJAX GN laptop whit (at least) two burned components around the supply area connector.

I would like to replace the broken components.

The chip is 8C630. Probably a supply regulator (i can't find datasheet on internet).

The second components is a smd resistor (or capacitors) without simbol or value.

The barcode green stiker on te mother board report:
NS1C6A00774-60-NJ5MB6000-B04

The mother board brand is ASUS

Any help is appreciated.

Thanks in advance Smile

hi everyone im just new here.

for the past few months im having this problem on my laptop its a toshiba satellite A205 4577. my laptop is working perfectly on battery only:cry: if i plug the adapter it will freeze instantly. it wont even boot if the adapter is plug in. but it will charge the battery if its on off state. so i can only used it for 3hours and then charge again.
pls give me an advice or guide how to fix this. they say its something to do with the power management circuit in motherboard.
i hope anyone can help me since this is my only pc that i can use for study.

17 Nov 2009 1:17 Re: 100% Repair Of Laptop & Desktop Motherboard

have acer extensa 5630 ez. It wont power on with battery or mains supply, At first it would power on after waiting 5 mins , this then extended to hours then days and now its weeks before i can power it up again. I have noticed that it will power on from sleep mode or if i press restart but if i close it down or put it into hibernation it will be weeks before it will power on again.pressing the power on button when its on mains power just causes the green light to go out. On battery only if i press power button on rapidly about 5 times an led orange light flickers I have tried the so called power reset and reseated the ram but these remedies have no effect. Have been on net and there is lot of people having this problem with this model…. i would appreciate any help.. Thanks

Hi Sandip,

I have HP Pavillion laptop that DVD drive stopped working. I tried replacing it with another DVD drive without success. I am guessing that mobo might have defective IDE interface, not sure how troubleshoot further and fix.
