You have a battery issue called " dead cell migration" This happens when the battery is used almost primarily plugged in. The Battery believes the Dead Zone is the end of your Battery life, when it is not. You could try a deep discharge by looking in your manual on how to do it. My guess ids that the hole has taken over and you need a new battery. First try to deep discharge and do a full recharge. You will then get two or three hours of Battery life.

My compaq presario sr1103wm doesn't boot up it


First of all.. try connecting all your peripheals to your PC.(monitor, mouse,keyboard,mic,speakers,etc)

Then u should open your pc and remove BIOS battery and leave it out for few minutes and put it back in...

if that doesnt work u should remove all your RAMS (memory chips next to processor) carefully and start your PC without them, u should hear some beeps, that okay, just a warning, after that put them back in and start again.


if that doesnt work try changing your hard drive with another one, or just take yours and test it somewhere else.

the last u should check your power supply, i see it starts up and then shuts down.. if your power supply is dead u couldnt even start PC, maybe there is a problem with your power outlet, try changing cables and outlets, if still doesnt work test your power supply on other PC.

if none of this works then u probably have issues with motherboard or processor.. then you should take it to service
:D

Compaq Presario v2000 notebook reduced battery life


you may try:
1) check the battery alarm at windows power managment, to set 5-10% alarm level.
2) discharge the battery to the empty then charge longer time, you need monitoring how long it charged (see charge lights change), need to change new one if charging time much less then before(less then 10-20 minutes)..
3) plug-in AC adapter monitoring charging current,
this step you need a current meter to make a series connection in the circuite, the battery is over life cycle if the current less then 500mA.

Battery doesn't stay charged


The problem is with the battery. All Lithium batteries last for around 1000 charges or so. Since the laptop is 2-years old the battery needs to be replaced.
I Hope this solves your problem. Kindly Accept my solution.

Laptop won't stay on


it might as well be a internal problem related to power or loose contacts with RAM or the power chords internally.
Better to go to the technician in this case.
Your first Battery would have been fine too..
