I agree with #2 here. Try that first. Then check the web to see if there is a new BIOS update for you. Then proceed to step 1 IMO.

I would try and power on with just the CPU in the board. Most motherboards will give you a beeping error if there is no RAM. This will at least tell you that it's POSTing up to the RAM check. This...

Yup. The motherboard is trying to tell you that something is wrong. You need to find your mobo manual or look it up on the web to determine the error beep you are getting.

Quick and dirty -...

No video signal? Any beeps?

From your symptoms, it sounds like the machine isn't completeing it's POST cycle.

Quick and easy - try to remove the RAM and power it on. You should get error...

I usually stick something soft like a zip tie end into the fan slowly until I hear it hit the zip tie. If it hits, I know the fan is working. If it doesn't - it's broke :-D

+1 I agree.

It's amazing that the laptop lasted long enough to melt the plastic! Usualy a capacitor just blows out and you get nothing after that. There is an off chance that it could be the AC...

+1 I agree.

I have an E6500. This is where the fingerprint ID reader would be installed if you paid for that option.

Sounds like you ran the basics of isolating the problem. Good job. You replaced the motherboard and you say it now powers up but you see nothing? When you power up with the new motherboard do you...

Hi, I had this same printer with the same issue. I went to Officemax to purchase new ink and found out that it was going to cost me $65. Yikes. I dropped 85 on a new photo printer and tossed the...

Also check where the AC Adapter plugs into the...

What Pressario is it? How old is that drive? You can get a replacement DVD drive for 10 - 20 bucks on newegg. That shouldn't hurt your wallet too badly.

Only other thing I would try is to power...

Which version of wonderful Windows are you using? Any Windows 32bit OS will not see more than 4GB of RAM. There would be no point in using 8GB unless you are running a 64bit OS. Yes, yes, there...

What game is it? I'm a big gamer myself and have had this issue in the past on different builds. Last time this happened to me, I was playing Battlefield 2. The game kept freezing on me and I...

Keyboard bezels are trickey. I always feel like they are going to break when removing them. I usually use a small screwdriver to help get under the bezel so I can wiggle it loose. Follow the guide...

Here are the basic troubleshooting techniques I use to find a "mysterious" problem such as yours.

1. Remove battery and set it aside - try to POST
2. Remove HDD and set it aside - try to POST

Hi. I've been fixing laptops for 11 years now. Wow I'm getting old. Anyway, if I had this unit in my shop, the first thing I would do is reseat the keyboard. 99% of laptop keyboard are very...
