Question about Sager NP9890 Notebook

1 Answer

Np9890v bought 11/2005 lcd screen goes black while pc lights and fans still on

I have been dealing with this for over a year and Last two weeks, I finally took it in geek squad in Best buy and I was told that it was a mere driver issue. I told them that I plugged in the laptop to another monitor and the display was showing but the screen on the laptop was not. So I downloaded the drivers from nvidia is the manufacturer of the card 7800gtx and also tried to update the driver from device manager as well. I got home last night and left the pc on all night and to my dissapointment, the lcd flat panel had gone black again. I googled the problem and I'm getting results that it could be a faulty backlight or inverter. Really I'm just exhausted with this laptop it was over a 3K purchase in 11/05 and I already shipped this pc once to California with Sager notebook while it was under the 1 year warranty when the harddrive became faulty on me. Now this. For the amount of money I spent on this 'supposedly' gamer pc it's beginning to seem I bought a lemon...

    do you have an external mouse---mine would go to sleep if the mouse wasn't move enough--changed a setting and fixed it--problem was that when it went to sleep--nothing worked.

If you can find the right inverter it might be worth replacing yourself if you are up to it.

Acer Aspire ,5535 black screen,on/off button ok,...insert dvd searching??power light on, batt charging light on,fan on..where to go next


ok, 10 year old laptop
step1 , as always remove the old dead shorted huge battery first.
run now? it will on AC for every if you want.
Led Glowing tell not much its just and LED, so dont look at them if on, unless and LED blinks codes. ok?
what matters is power, power is first. no power no joy, ever.
so out the battery now.
Put in a new RTC coin cell battery next 7 year life rated you are 3 years past that at 10 years old, (end of useful life that)
next is fans, , ok fan is on.
next is what, TEXT got TEXT ON SCREEN>? ANY THING??
I guess ZERO SCREEN anything of any kind>.
we next use a flash light, this PC has crummy , CCFL back lamp tubes that when dead screen goes, dead, as most have this old.
only few never used laptops last 10 years old.
so with the flash light (dark room) at an angle shin the LCD
see data, now on the screen, yes, that is a DEAD CCLF.
on ebay you see them selling new CCLF screens for this PC.

my bet the CCFL are dead. as most are this old.
All laps this old fail in this order,
BIG battery goes bad or shorts.
COIN cell dead.
CCLF dead ( ended about year 2010 , LED back lamps began)
HDD dead at 5 to 10 years old.

this is all Expected. all from carbon14 dating a PC, I can say that.
yours is 2008 made.

If it's 3 weeks old return it. Or you can do a System Restore/Recovery. Take a look at this forum for the Restore/Recovery Procedure: http://en.community.dell.com/owners-club/alienware/f/3746/t/19441985.aspx

Compaq Presario Laptop half screen issue


no photos of the screen presented.
so all i can do is guess what it looks like,
its so old HP has no info on it. legacy PC, called retired.
i guess 10 years old
2007
so one side is dead, black screen right?
and if you shine flash light on the black side, is there data there or not?????????????????
the v3000 is a CCLF back lamps (edge)
and last 20,000 hours max, (very very short life)
so when one side fails. it goes black
the bulb does or its inverter, supply does.
all do this everyone,
all go dim
then blink
then die, or are random starting.
just like a florecent light in say your garage, same deal. same gas tube.

use the flash light, see its not really BLANK IS IT
only the black lamp quit.
endless post here on topic,


in the year 2010 most of these ended and are now all LED
ending all this pain.

Dark Screen and flickering black screen


I am having the same problem and I think it is the bulb in the TV or the board that the bulb is on. Only had mine for 4 weeks!! Apparently this is a common problem with LG TV's that occur as often as 3 times a year with a minimum cost of £290 just for the bulb!! Wish I had known that before I bought it!

Would recommended contacting the store you bought if from and ask them to repair it seeing as it is so new, I am awaiting the engineer at present!

Monitor does not work


sounds like a slightly damaged power supply. try powering up with an equivalent supply. if only an ac wall cord is plugged in for power, then internal supply is at fault
