Compaq Presario A900 won't start

[davisunit]

The problem is the blue ring around the AC adapter plug lights up when plugged in, but it blinks non-stop.

Following the online troubleshooting, I've:

1. Unplugged AC, removed battery, held power button down to drain system, then reseated the ram (twice).

2. With the battery still removed, and plugging in the AC, the blue ring lights up and blinks. Pressing the power button does nothing.

3. With the battery installed, and no AC, the blue lightning bolt icon blinks 4 times when the power button is pressed, but computer does not start.

4. With the battery installed and plugging in the AC, the blue ring and lightning bolt icon both blink non-stop.  Pressing the power button makes the lightning bolt icon go out, and the blue ring stops blinking for about 3 seconds, then both lights return to their blinking state.

Sometimes, pressing the power button  causes all lights to come on, the fan spin up, then it shuts down - sometimes briefly getting to the opening black/white screen, most time not at all....basically, it shuts down quick.

Any ideas?

I have exactly the same problem with my Laptop which is a Compaq Presario A962TU, it will boot up normally about 50% of the time. I have upgraded to the latest bios and that made no difference either

COMPAQ presario V3822AU  cannot power  or won't start .  So i sent  the  whole  unit  to  it  service center ,  they  said  motherboard  problem  , need  to  replace  a new  one  for total cost  of  RM 1100 (included all labour  charge twice) .  next  time,  we should not  buy  HP  product  at  all due to  not  reliable  .   i   would  happy  to  look on  ACER  which  is  good in  price  rather  sent it  for  motherboard replacement  and  expensive  extended warranty as  they  wouldn't  offer  3 years  extended care  after  your  laptop spoil or  expired care . More over , They  charge RM 198 for  1 year  care .   i  wonder  presario  product  is  low  end  or  low  quality  which  use  after  13 months,  hardware  problem.

    Change  to ACER  and  get 3  extended  warranty package  for  RM  198.

If  i on this  situation, i will  buy  new  one  and  break  my  relationship with  HP  as  Customer .  This  because  it  leave  us  first   bad  impression .

I am experiencing exactly the same problem with my a900. When I turn on the power, the fan spins for a few seconds and cuts off, the screen is totally black, the hard drive does not spin. In fact nothing really happens- the system is simply dead. I am desperate to know what's going on. Please help - this laptop is like new and I really need it for work.

I have the same problem thought it was the battery bought a new one  still won't start up.  I show power to the computer the green light stays green.  Could it be the mother board?  If so do you have to replace the mother board or a comp part.
