| 463495 | 2006-06-16 00:26:00 | This is a huge longshot but I thought it worth a try. This is about a Compaq Presario 2500 laptop owned by my daughter and bought new about 2 years ago. While still under Guarantee the backlight for the screen cut out a couple of times but only for a few seconds, so it was never reported. There is NO DOUBT it is the backlight as with room lighting at the right angle it is possible to use the computer but with great difficulty. 4 months out of G/Tee it failed and after much fighting with the shop/hp they replaced the Backlight. It was fine for a month or so it faulted again. Returned to the service agents but they were unable to make it fault and this has happened 7 times since the original replacement. Some times it faults but corrects itself before we can send it back, other times it goes down to the HP service company and they are unable to make it play up. What I wonder is if anyone has had a similar problem. Many thanks for reading this. Tony |

| 463496 | 2006-06-16 03:39:00 | I've got an old (6 years or so, which is ancient for laptops) on which the backlight drops out from time to time. It seems to be related to the contacts of the cable feeding it. I've dismantled the screen a few times, after the first time when it failed completely and I suspected the little inverter which produces its high voltage. Now I just work the screen back and forwards a few times and it comes on again. Sometimes it seems to depend on the angle of the screen. Intermittent failures are the very worst things to fix. You never know whether you fixed something or whether it just decided to work again, your "repair" being irrelevant. :( |

| 463498 | 2006-06-16 04:59:00 | It must be a hard life buying laptops, I only hear or see intermittent problems for all the benefit of portability that they bring. Compaq and Toshiba alike are built to last but seem to have faults with bad connections and bits getting "funky" for want of a better word. A fix could be to get a second hand or kind computer spare parts person to fit another screen onto the laptop and see if it is the connection of the screen or the actual motherboard connection. Bits can be replaced sometimes but can be costly or just hard to play with in laptops. (lots of things to undo and fiddly bits in laptops) Don't get me wrong its not on all but just a luck of the draw and how they are cared for. Try and get a few troubleshooting guides off the internet and pull it apart and see if something is loose. |

| 463499 | 2006-06-16 05:10:00 | In my case, freezing and heating wouldn't make any difference . Even eyesight and motor skills (apart from those needed to dismantle a laptop) aren't all that helpful . Luck does help in some cases . My major problem is a cable "exactly" the right length which connects two hinged units . It's the relative movement which does it . If the cable was even a few mm longer, I'm sure the problem wouldn't occur . The sub-sub-miniature connectors are not repairable or even (realistically) replaceable . I just live with it . A bit of fiddling brings the light back . Swearing helps . It makes me feel better . I would not like to be paid (or pay anyone else) to repair laptops . :D |
