Hi everyone... hope u all can help...my advent 5311 laptop m/board was broke at the dc jack point.. so I got the exact same mother board replacement from e-bay and proceeded to swap the parts over from one board to the other..eg cpu....wireless card,memory,heatsink and fan,hard drive etc.Anyway ,after rebuilding I plugged the power cable in and was happy to see the green charging light...but when I powered up the laptop all I got was the power light,the charging light and one flash from the HD light then it went off... there were no sounds and the screen was black with a very faint glimpse of the Advent logo scrolling...anyone help me please.... ty in advance..Dugg88

Hi Dugg88

there were no sounds and the screen was black with a very faint glimpse of the Advent logo scrolling
If you look very closely at the screen can you see any very feint graphics in the background ?
If so this could be the inverter or back-light.

Was the m/board new or used?
It could be that you have been sold a defective board.

It does sound like a dud !
Contact the seller and ask for your money back.

eBay have a strict code of conduct - so you should be OK.

The seller saying that it has been tasted and working is no guarantee that it actually is.
The fact that it "was working last time I used it" is no guide to a working m/board.

Send it back - good luck :)

Hi, from what you say regarding the old motherboard, and providing the board is still OK and not damaged elsewhere, there is a good chance the broken DC power jack can be replaced, therefore rescuing the system that way.

If you are confident in doing a soldering repair, and that is entirely up to you to risk doing the job yourself, if not I recommend taking it to a competent repair technician.
However have a look here at this laptop repair specialists site :-

Thanks for the feedback, I did say replacing the power jack was easy and a tenner is a good price for that job, some places might have charged a lot more.
