Compaq doesnt power up at all

I got a friends Compaq Presario 700 to repair. she did not use it for the past two months and all of a sudden we tried to power it up and nothing. power source seems to work (light is on and power tested) i tried to unplug it without the battery and pressing power button for 30 sec but no luck still does not turn on...?

    well thank you for your response however i did take the mem out tried power start and still nothing. when you mean clean the memory you mean blow dust etc off it right? i did that and put the chip back on still no power. it is strange. i did take the pc apart and took the little round battery out to check if it is ok and it read 2.7 volts so the little battery is working too. all power source seems to be fine so i dont know what else to do now?

  • sxristi Nov 24, 2008

    it is a compaq presario 700 laptop.

  • sxristi Nov 24, 2008

    yes i tried removing the battery too. still nothing.

  • sxristi Nov 24, 2008

    i applied pressure to the pin with a small flat screwdriver and it seems very stable..
    i took out the flat battery inside the laptop and its voltage is 2.7 so it works i think fine.
    i also tested the power supply at 19 some volts
    so now i read something about testing the battery because some units dont work on a dead battery. i am not sure how to get the battery tested because it has a grid of terminals so which is + or -? anyhow keep up the feedback. thanks

    thanks :|

    finally after leaving the laptop plugged in for several days the battery was charged and it did start up. Thank you all for your advice.

  • sxristi Dec 03, 2008

    well it is me again. and i need to report for informative purposes that after a format and new copy of windows and drivers the compaq is back to not responding status...so i guess that maybe the battery is not the problem that i had assumed. :(

  • sxristi Dec 05, 2008

    Several days have gone by and I have noticed the following...When I leave the pc plugged in the power supply with or without the battery for several hours (6-7 hrs) the power light comes on and I can start the pc. I can do numerous restarts and leave on the pc. However if at any time i shut down the pc then it will not restart and the charging light will not be on. At which point i will have to leave it on again for 6-7 hours for the light to come back on so i can start up the pc again...What do you thing the problem is? Internal 2.7V battery mayb? or something else?

    is this a desktop or laptop?

    have you removed the laptops battery (not the one on the motherboard) and tried it on AC power only?

  • Lee Hodgson
    Lee Hodgson Nov 24, 2008

    ok, now look at the AC adapter on the laptop to make sure that the pin is not loose or broken inside

    + is the top of the battery - is bottom (where the grid is) you could try a new memory module in place of the existing one to make sure its not the memory that has gone faulty. Appart from that you have done just about everything you can do at this moment in time, if a new memory module does not start the machine then chances are the motherboard has failed
