A cousin gave me her:
Product: HP Pavilion dv2500
p/n: KN996UA#ABA
dv2810us
laptop that has no power at all. I can charge the battery, and that's just about it. When I plug in the charger, I get a small blue light on the charging port and a few seconds later, I also get a small blue light on the left hand side indicating that it is charging.
The problem is that it doesn't turn on at all and there are no other signs of life. If the battery is low, the battery light flashes quickly and that's it. When it's charging, or the battery is full, nothing happens.

I'm not sure as to what it could be as it could be numerous things.

Does anyone have any suggestions as to where I should look? I have a disassembly manual from HP, so I can easily take apart whatever I need. Thanks.

P.S. This isn't the only problem its had. 1/2 a year ago, she told me that it would boot up, but the screen wouldn't turn on. I "fixed" this by plugging in an external monitor to the VGA port and then using it for about 10 minutes w/ the ext. monitor. I then shut down the laptop and removed the ext. monitor and turned the laptop back on, and the screen finally turned on, weird huh?

 
"The problem is that it doesn't turn on at all and there are no other signs of life." Your statement with power plugged in ONLY (no battery) and it doesn't turn on at all that is it. There is no fix, other than spending too much money to try and replace with someone else's 'used' hardware, which isn't cost effective.

Considering a i3 8GB DDR3 1TB Laptop is only $249 at Walmart, which is 1000% more powerful than that dead system, to try an get parts (used and unknown condition) and try and fix this wouldn't benefit for the cost and effort in comparison.
 


So, with all the references you have, "MIS, BSIT / BSA, ITIL Foundation, CompTIA A+, MCA 6294 Certified Planning and Managing Windows 7 Desktop Deployments and Environments" if your Alienware M17x R2 has no power, you're not going to try to fix it, you'll just throw it away and buy another one.
 


1) The OP by his own statements shows he is "Joe NonTechUser", not "component level triage and resolder specialist with OHM meter in hand". So the point for the OP is it fixable or not, simple answer.
2) This is a laptop, that means customized parts that are very narrow available (i.e. you can't just grab something at Walmart and just install it into it) especially with power. Given that the power is flowing via the circuits to the battery, indicated the motherboard itself may be the problem since it won't power on. The ONLY test is to remove the battery (as I suggested) and be on ext power only, does the laptop turn on now - many cases laptop batteries at End Of Life will interfere with the power circuit. This is the only power solution short of a serious technical component level diagnostic (note he said NOTHING AT ALL turns on, this isn't simple BIOS reset, reseat RAM, swap GPU, .
3) As this is a VERY OLD (Vista for cripes sake!) laptop no longer supported by ANYONE (HP, AMD, NVIDIA has that card on the NO LONGER SUPPORT list for example) and is out of warranty, there is no support mechanism the OP can turn to.
4) That leaves (as I noted) getting 2nd hand parts and replacing whole components, which still risk that A) the parts are end of life B) are out of warranty C) subject to failure as well considering the age and use D) will not be cost effective when considering a new system, under warranty, with new updates and better performing parts is ONLY $249 (consider that just getting Windows is $179 by itself!!!).

Yes the market has changed to the consumer demands of 'disposable' computers (look at the cheap prices of tablets / laptops) akin to the accepted CellPhone-Replace every 2 year model. Pricing for both smart phones (often now counted as computing devices) with tablets/laptops/Phatablets as comparable, and are much cheaper than buying individual parts to 'build' a portable platform and (as noted in item 1) less 'technical' for Joe NonTech User.

This is a old piece of unsupported dead equipment that unless your a hobbiest looking to do component level soldering and OHM meter testing, that makes no fiscal sense to waste money on. So YES that is my answer, NEXT?
