Question about HP Compaq Presario C304NR Notebook

Compaq wont Boot

The other day my son said that the power supply on the computer stopped working. The light would not come on and stay on. It seemed as though it may have shorted out.
He said he was able to boot it up for a short amount of time off the battery but it went in to the factory restore and then it shut down. I went and got a new power supply and all that happens is the power button keeps flashing rapidly and so does the lightning bolt on the front of the computer. The computer will not boot. I read that a gentleman had the same problem as what I am having and he replaced the Motherboard and that did not solve the problem. If it is not the Motherboard what else could it be?

    My problem is that I think my battery wet bad and caused my charger to fail. I purchased a new charger and got a different battery. When I plug in the ac charger the charge light blinks. If I push the power button it also blinks and the computer will not turn on. Any help with the blinking light would be appreciated.

Apart that replacing the motherboard on a laptop is a difficult and expensive operation, component inside must be tested, as the problem is not necessarily the motherboard.

Try first starting the laptop without the battery, and only power adapter.

If it still does not start, and the AC charger has the right voltage (the one written +- .5 on reading) the laptop must be taken apart and tested.

The most likely is that the AC socket on motherboard had shorted or another component near the socket had blown because of the original accident.

My gateway 700 xl doesnt boot


Unplug the power from you 700xl and from you monitor. Try removing the cmos battery and reinstalling it. Then, plug everything back in and try restarting. If it continues to give you the yellow light, you may need to replace the CMOS battery, especially if it is more than two years old.

Another thing to consider is if your power supply is underpowered for the number of external devices you have plugged into it (i.e., cd, dvd, external hard drives, printers, pci cards, etc). Gateway installed very low powered power supplies in their 700xl desktop computers. Usually only around 250 watts maximum.

If you are replacing the power supply with another 250 watt maximum power supply, and you have a lot of external devices plugged in, you may need at least a 350 watt power supply....if your CMOS battery is not the problem.

My son changed towers and upgraded to another power supply


How long have you waited for it to boot up? Sometimes I have seen it sit on the logo for like 10 minutes thinking about the boot configuration. Also you might change out your hard drives and cd's and DVD's and check your jumper settings on all of them to see if any conflict with each other.

Wont start up


my wife has a presario that had a similar problem - it would boot up, then immediately shut down. I took off the side plate and blew off some of the dust inside. that worked for a couple of days then the symptoms returned. I took it apart again but this time I removed the cpu fan and the cpu heat sink. I cleaned all the **** off the fan and the heat sink and replaced it. this time it stayed on. I checked out the power supply. compaq installed a very cheap power supply - only 250 watts. a replacement power supply for the same machine but with an output of 300 watts is available. as soon as I can scrape up the change, I'm gonna change the PS

Boot up problem


It is possibly the RAM it may have ceased. Look at it underneath held in by two screws. Take it out and examine it then put it back. The motherboard seems ok because you said the lights are lighting up. Sometimes the ram can stop even the bios and nothing can boot up.
