Compaq presario 2500 notebook won't boot

OK, here's the background with this computer.

This laptop has been "shelfed" for about a year now, but the other day I decided it would be handy to fix. I'm a poor college student so I don't have to blow sending this to a shop somewhere, and I'd like to get it working again. The original problem was that it wouldn't (usually!) boot at all - it seemed to be completely dead. I would plug it into it's a/c adapter and press the power button, but NOTHING would happen. Occassionally, like once every ten minutes or so, an orange led light in the front would flash a few times. (the led with the thunderbolt symbol, I think it's the "battery charging" led) What was strange though was that sometimes, for reasons beyond me, when this orange led flashed and I pressed the power button, it would SOMETIMES boot up into windows and run perfectly. But this was only like once every 30 mins or so - I had to fiddle with it for half an hour to get it to boot. The trick where you remove all power sources and hold down the power button then tried to reboot worked a few times, but then suddenly quit working and the computer wouldn't boot at all - not even after fiddling with it for half an hour.

I was pretty sick of this so I took it apart and wiped some dust off the heat sink. Everything looked OK so I put it back together. Now, I have a new problem. When I press the power button a bunch of blue leds light up and the fan kicks on, (whereas before everything but one orange led was completely dead) but there's no display and nothing boots. Anybody have any idea whats wrong?

(on a side note the battery is dead, and i've tried everything I've with with the battery in and out)

This sounds like a weird solution, but it worked for me. I recently bought a used Presario 2500, it worked when the guy showed it to me, when I got home it didn't work two days later. I tried several tips from the web, finally I started pushing several buttons randomly. I pushed the Email (Envelope) button, and the computer powered on suddenly. Now, the Envelope button is the only button that will power the computer on. When the computer is on, that button will also bring up Outlook, but when the computer is off, that button turns it on. Let me know if this fixes it for you.

My compaq notebook presario cq50 210us is frozen on a black screen


Try the laptop on an external monitor, if it works ok on that, the fault lies with the laptop screen
If it does not work on that, the fault is with the graphics chip on the laptop

If it was working ok then suddenly died, check to see if you can boot to safe mode (F8)

repost the results

Presario 2500 notebook boots up only to hibernate


Sounds like a poor power connection on the motherboard. Unfortunately, this isn't an easy fix - you have to completely disassemble the laptop and resolder the power connector. To check and see if this is the case, you can plug in your laptop, set it down on a table(so it doesn't move or get bumped), wait for it to start booting up, then gently wiggle the power cord where it connects to the laptop. If the computer shuts off, then it is, in fact, a loose connector.

It's def not software as i've reinstalled, but i only get 1/2 way through it before the pieceof **** shuts down. When you goto restart it has no screen, no hdd activity, just fans fireup and 3 blue lights next to the power button, i told be friend that the only way i could fix this is with a hammer and sticky tape...he...he.
