Is my dv2500 dead?

hi all...
today i tried to boot my dv2500, it boots with no signal on screen the screen is lighted but no signal from the computer...
could u tell me wht z my problem...

thnx

 

Sounds dead to me. See if it's on this list:

the dv2500 wasn't included in that service enhancement. connect it to a external monitor see if you get a picture. Do you have a Nvidia 8400m Card in this notebook?

 

it wasn't included there i've also tried external VGA and HDMI but the problem still persist, my windows boots normally and it's configured to immediate display when output connected . but the thing i've noticed tht the low level booting wasn't displayed, it must be displayed since no driver controls this. about GPU yes i've n8400m and i read the symptoms of the defect they said tht the screen must had no light but my screen lights are on.

 

Try taking out your battery pack and AC power.

Hold the power button for 30 seconds.

Now try starting up again with only AC power.

 

the same

 

Oh make sure all external devices are unplugged (USB, CDs, etc)

 

flipfire, resetting the BIOS won't help, I'm pretty sure. The way his laptop failed looks exactly the same as it has happened to many others with GF8400 in their HP machines.

 

It has the same symptoms as the USB bug, wont boot up, the screen just lights up.

Wouldnt hurt to do basic diagnostics.

 

everything unplugged, i did reset the BIOS but still

 

so do u thing that i've GPU defect? but as i know if there was no GPU detected the computer wouldn't start at all

but i hear windows starting sound means windows successfully started but the problem with output on both laptop screen and external

thnx guyz

 

if you gpu is defective you will still hear all the sounds of the pc booting, there just wont be an image. it sounds like you have a defective 8400

 

thnx j-dogg, here i think i've no solution my laptop is out of warranty... any solution?

 

Did you press FN+6 or whatever the switch screen button is when you plugged in the external monitor?

 

yes on my keyboard Fn + F4

 

Call up HP anyway and tell them your Nvidia card has failed. Be persistent and persuasive, a case manager might honor the extended warranty even though your model isnt listed.

 

thnx flipfire, i hope they replace it anyway...

 

i just went through the same ordeal call hp like flip said and tell them you have a defective 8400 make sure you get to a case manager they are the only ones who "know" about the defect. the cards seem to all be dying at the same time, this is the 3rd dv2500 thread with a dead card i've seen in less than a month.

 

I have a feeling mines next...

 

YOU HAVE JUST BEEN F'D BY HP AND THE 8400.

Welcome to the club.

Man oh man when I get stateside... I am going to unleash heL

Call the dbags up and go apeshT on them. That's my plan.

Speaking of which, guys, do I have a better chance of getting the 8400 repaired or them sending me out a new system? Do they even make these pieces anymore?

The really F'D part is that this system is the bloody replacement system for the original F'D machine.

 

yea it sucks, there just going to replace the blown 8400 with another crappy 8400 thats going to die. then they install the latest bios update to make your fan work overtime to prolong the disaster from happening again

 

lol i'll ask them for free repair and must be persuasive and aggressive. it's not my mistake...

 

i installed the new bios 2 weeks ago

 

My first dv2000 with a 7200GO died within 6months (definite defect)

My second dv2000 came with integrated, been alive for a year now.

My third, dv2500 with 8400m GS has been alive for 1 year 3months now. I overclock it often and stays in good temps, its got the copper mod and its undervolted.

 

how much cooler does your run with the sheet of copper on the gpu and being undervolted?

 

same question ^

 

How the heck you manage to undervolt the bloody thing? I had the POS underclocked to 200/300 (50%) but evidently that did shT else.

The copper mod sounds like it would actually help, although taking apart the laptop sounds like a major pain in the aS.

But ya... what sort of temperatures did you get? Be really interesting to know just in case the SOBs send me the same 8400 back but fixed- doing the copper mod would probably be the very first thing I would do if it dropped the temps down considerably.

But I am going to keep screaming until the SOBs send me a new laptop... at least that's the plan anyway. lolz.

 

mine wasn't underclocked the GPU temps reached ~ 80 - 90 C or even higher and now seeking free repair :S
