Question about HP Compaq Presario C500t Notebook

My Compaq Presario C500T lap top won't start

I don't think it's the battery, because there is an orange light that flashes when I press the power button indicating some kind of power, although I don't know if there's enough power to turn it on, but I'm just guessing, I know little about computers. Before this happened I noticed that without the charger plugged in to the lap top, a fully charged lap top would lose power pretty fast, some times like in 10 minutes. So i'm thinking mabe it could just need a new battery, but with that orange light flashing when I try to turn it on, I'm not sure. I don't want to buy something I don't need. So my question is, besides the battery what else could be the problem?

    I got ripped off... A German Student at USU sold me his computer. He said it worked fine... But he was in a hurry and since it turned on I thought it was ok (what a waste of $330). I got home and the battery still had a little charge in it so I plugged it into the wall, but after like 20 min it turned off on me, then I turned it on again. This time it only lased like 5 minutes and turned off.

    I took the battery totally out and with the AC Adaptor plugged in, light on the front comes on, so it’s getting juice, but as I push the power button it comes on, then starts to flicker (flash). The computer will not turn on. I think if I can find a way to charge up the batteries I think it will turn on... I have used a new power AC Adaptor but the same thing happens and it will not turn on...

    Please Can anyone help

Generally speaking, an orange power light indicates problems with the power. You also described to a "T" how a bad battery behaves. To test this theory, take out the battery and plug in the laptop. It should power up and run. If so, it's time to invest in a new battery.
To be doubly sure, if you have anyone with the same laptop as yourself, plug in their battery to your laptop. It should work if their battery is good.
Thanks for using Please rate this tip accordingly if it provides the information you needed.

    How secure does the connection feel when you plug in the power adapter? Remember when you first got it and it was secure and tight? Is it still that way? A big problem with laptop is the constant plugging and unplugging loosens the connection so you end up having to jiggle it to make a connection.

Compaq Presario V5000 does not come on

The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

I am opening my pc and after 2 second it went off i have a blinking light like a orange flash light

I imagine the orange flashing light is over the battery? The compaq laptops have a little blue light that will typically light up when it's plugged into the wall. If it is plugged in ensure that the little blue light is on. If it isnt you may have a n issue with your power supply unit, or there may be an issue with the port where the plug is plugged in. Thus causing the battery to be dead and the computer not power on. If you have any other compaq computers you can also try plugging in that power adapter, or try picking up a universal or another hp/compaq charger from somewhere such as best buy to test it out.

Presario C500 Wont turn on

sounds like the d/c adapter was either installed backward or the wrong part was installed, also check the connector on the new power cord to the laptop, you may have gotton an incorrect power cord. because what you describe is the internal power system is shorting out. take battery out and check it with a volt meter , if the is no volts/or negative volts on the battery ,it has gotten internaly reversed , and needs replacement.

Flashing lightning bolt on Compaq C300

This sounds like a battery problem. The best way to test this is to remove the battery and then power the laptop up with just the power cord plugged in but no battery. If the computer boots then the battery is bad you will need a replacement. Also try letting the battery charge for a day. Be sure that the charging light is coming on when you have it plugged in.
