I have got myself a pesario v6500 from a friend- (reasonably new computer) they said that they left it on a bed overnight and have fried the harddrive- ( after taking it to PC world they said the hardrive was fired) i have bought a new 320 gb drive and replaced it (quite easy process) i cant get the computer to switch on- i have the blue power light at the source plug but thats it?? help.. otherwise i've just wasted 70 quid..!!

You might have fried your ign control modual

you didnt tell what code is assuming evap large leak and that the fuel pump -evap connection is culprit --fuel pump $200+ drop fuel; tank and replace pump 200 is reasonable go get another estimate from someone else and to do yourself buy a repair manual about 25 for chilton / haynes and see if your capable of dropping an approximate 6 foot fuel tank

The monitor screen on your laptop is an LCD screen.

An LCD screen cannot produce enough light by itself. It needs an additional light source.
The additional light source is a Backlight.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.

LCD screens are a composite of layers. The layers are held together by a metal frame, much like a picture frame.
The Backlight is usually located on one side, accessed after removing one side of the metal frame.

As stated, a Backlight is a very small type of Fluorescent lamp, (Tube)
Very fragile, easily breakable, and not usually approached by one who has very little, or no experience in replacing.
More common the entire LCD screen is replaced, which includes the Backlight already installed.

A laptop also needs an Inverter to provide power, both for the LCD screen, and the Backlight.

90 percent of the time the fault is the Inverter.
I repeat, 90 percent of the time the fault is a bad Inverter.

An Inverter is cheaper than an LCD screen, and MUCH easier to replace than a Backlight.

Allow me to show you replacing an Inverter on an HP Pavilion dv6000 series laptop.
Granted, it isn't an HP Compaq Presario V6500 series, but the principles still apply the same,

Granted this is not what you asked for.
My premise is to teach, and hopefully save people money.

Well contact your dealer and tell them that your battery is gone bad for no reason and don't mention you let the light overnight because your battery is under warranty and they will put in a new one. Good luck

Remove your battery and try with external power supply again if it boots up all good and proper then after booting to SOE refitt the battery and let it charge - if it doesn't boot or power on look to see if the blue LED it on around your power input point. If there is no illumination around the power input port try another 65w power supply input - your power pack may be dead. Cheap fix - if it still does the same powers on then off - you have reason to go out and buy a new laptop - would be cheaper than replacing the M/board
trust me.

Yes the problem is with your Ethernet card, change it...

well yes the battery is pretty much fried but you can get a new battery online from nintendo

Yes all motherboards are replaceable, Your just going to have to find the correct part # you need. The motherboard shouldn't run you more than 100$, although a repair shop will charge upwards of 300-400$ for the time to install.

i need all drivers of compaq presario v6500.. pls... help me!!!!! thanx

Tough call on this one as it could be that a motherboard component was fried. Have you tried to do a soft reset on the unit by pressing the menu and center buttons at the same time for 5-7 seconds? Believe it or not, sometimes that resolves the issue.

The other option is to get us your unit for our FREE Diagnostic Testing. We will inspect the unit on our test bench, provide you with a repair estimate as well as a recycle price in which case we would buy your broken iPod from you for recycling.
