Question about Compaq Presario R3000 Notebook

Lights Flash, but won't Power Up...help!

I have a Compaq C300. I tried to find one on this forum, but had no luck. It won't power up. I've tried new AC adapters. I've checked the DC output. I've replaced semi conductors on the motherboard....and still nothing.

The lights flash for a second, and the fan kicks on...and then it just dies.

I've heard that the LCD screen has a glitch that may cause this...but I've heard it was RAM related.

I really hope there is a cheaper alternative than replacing the motherboard.

It's a $450 PC. Paying $300+ seems silly, but I don't want to have to BUY another PC.

Anyone able to help me?

Hi,
Did you happen to notice any brown spots on the motherboard when you were replacing the conductors? There seems to be a short problem with these models. I've had 4 or 5 with the same trouble.
Let me know.
Thanks

    yep. Try ebay. I wouldn't buy it from HP.

    Have you tried just 1 stick of memory, and applying pressure on the memory slot as if to push it into the board while booting?

    Might be worth a shot.

    Sorry I don't have better news but my experience has been new board.

My compaq presario c300 wont start up, power button illuminates the cooling fan kicks in then all the lights flicker and it the swithes off,


This is exactly the same problem as I have. I have changed the power brick and the battery but the problem still exists. PC World were useless and said it "probably needed a new motherboard" although I doubt this is the issue. It worked when I first put the new battery in, until the initial charge ran out. Did you find a solution?

Hi any one help.. the problem with the compaq presario c300 is when i try to start it up the only response i get is the lights on lap top flash rapidly.this is the lights on the front as well as the...


the flash or blink codes you can log on to this site http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&lang=en&product=3213867&docname=c01732674
and reference the blink codes. this is also the c300s service manual so you can go back and forth on other things. but if your swapping the motherboards then my suspect is your power supply. make sure that the C300 is getting 18.5 or slightly above if your on a digital meter. but if its below then it wont have enough power to turn on. speaking of power it could be the jack, the pigtails to the motherboard or a loose connector on the wall male end. so make sure to check your path of power from the wall to the unit. and follow electric guidelines and dont shock yourself. but what I used is a paper clip to put into the male end of the Dc voltand the inside is positive and set your ohm meter to DC 20 and it should read 18.5 v.

Compaq Presario laptop C300 - issues (orange light)


Sometimes when a PC gets stuck in hibernation mode, the only way to reset it is to remove the CMOS battery for 10 minutes and replacing it. It resembles a large watch battery and is usually located near the center of the motherboard.

I turn on my compaq presario c300 and it immediately take me to an enter power-on password screen


Hello,
A password on boot is not set by default. The owner activates this option. If some prankster or michief maker has entered a password on boot on your computer without your knowing it, there is nothing you can do, save taking the machine to an HP Certified Service Center to have the password removed or reset.
As the password on boot is a deterrent against computer thefts, you might be asked to show proof of ownership. This certainly is the case with Toshiba laptops.

Hope it helps.

Looks like a bad motherboard ,have you tried another power adapter the one that connects to the wall socket.
The motherboard could cost over $100 ,chepaer on Ebay or you could take it to a Compaq/HP service center and ask for a quote on the repair.

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.
