I have a HP DV2000. The 4 wires on the microphone connection where it plugs into the motherboard came apart when I took it apart. Must have had too much heat. Can you tell me how to connect these wires up properly?

I have a Toshiba P105-S9337 where everything is running fine (yep, I know – I am lucky).

I have one annoying issue: The screen stays black after pressing the power button until it reaches the Windows Logo/logon screen. This happened a while after I got the lappy – it must have been an update or something. There is a slight change in the brightness however I think that is just the tubes powering up.

This means I can’t see any of the BIOS prompts, etc.

Not a huge problem EXCEPT I am upgrading my HDD. I can’t see the Windows screen when it pops up to start the “repair” after booting from the hard disk.

Any ideas how I can get the screen to show the boot sequence again? I am afraid it may be a Catch-22…

Hello,

I have a Toshiba P105 9312 with a Nvida Go 7900 Video Card. A few weeks ago the screen went blank and the computer started running super slow. The screen randomly blacks out from time to time. I have ordered a inverter for it and am still waiting for it to come in. When the LCD is black the lights on the back of it still light up (I took the bevel off and have yet to put it back). I have checked all the cables and none were loose and the video cable doesn’t seem to have a short in it because when I move it around nothing changes.

In regards to the LCD screen if the video card is the cause of the problem is there anything I can do since the card is integrated into the motherboard?

In regards to the computer being very slow, can the video card be the cause? I have put a clean version of windows on the computer and even replaced the hard drive but the it didn’t solve the speed issue.

Would like some advice to see if I need to just scrap this laptop and buy another one or invest and try to save it.

Thanks.

My Dell laptop has been giving me these strange horizontal and angular lines and dots on my screen with different characters on the text as well. Tried reloading fresh windows and drivers but still the same finally came across technomart. They fixed the video chip fault and it is as good as new.

I have the same problem, but on my HP Pavilion. Have you found a solution. Only thing I can come up with is that the video card is done!

I have a Sony Vaio VGN-A317M, where the screen went black, shortly after bootup and stayed dark.
I plugged in my external monitor and the picture looked fine.
However, as I connected the VGA cable, the laptop screen came back on, as it switched resolutions.
Mostly, the laptop screen doesn’t come on at all, so I have to use the external monitor.
Sometimes, it is on briefly but flickers and goes off again.
I can sometimes get it working by plugging the VGA cable in/out.
When screen is working, everything looks normal – no unusual lines, pixels or blocks.
Because the screen is clear and sharp, with no visible defects, the graphics card (and screen lamps) seem ok but there might be a dodgy connection somewhere.
Otherwise, a windows driver issue, because the screen comes back when there is a change of resolution (as when changing to external monitor).
The problem with Sony laptops, is they use bespoke drivers, tailored to the machine. It won’t allow me to use the latest Ati driver.

I have a Toshiba Qosmio F20 137,running Windows XP Media Edition and its about 3 years old. A problem has developed without warning. When I power up, with or without the mains plugged in, the start up screen appears with the XP logo but there are vertical dashed lines right across the screen.They are in batches of four lines and there are ten sets of four across the screen. After a few seconds the XP logo disappears as it would normally before the blue logon screen comes on but the screen goes completely black. I have connected to a friends external monitor and the same thing is displayed on that monitor, which makes me think it is not the LCD or the inverter. I have reloaded the recovery disk, which seems to go through the entire set up, whilst this is running the lines are still on the screen but the display and progress bar is clearly visible. At the end after removing the disk and pressing CTRL ALT DEL to reboot I am back to the same start up and black screen. In safe mode (and also safe with cammand prompt)there are no lines on the screen, but as soon as it is loaded an error box appears stating ” The system is not fully installed. Please run set up again.” I have done this three times and still no difference. As I’ve only got a black screen, its not possible to look at any of the systems or drivers or in fact do anything else.
Any help would be very much appreciated

The Dell Latitude D810 monitor never came back on after I put it to sleep with Fn+Esc (sleep). Usually I close the laptop which puts it to sleep but this time I decided to do it differently. When I boot the computer everything comes up including the Windows XP loading sign, than it just goes dead black when it comes to the log on screen. (colors are fine when booting) I plugged in my desktop monitor and everything works perfect. My ATI display manager shows the laptop monitor disconnected. (Radeon X600)

I’m hoping that it’s a simple issue but and nothing is wrong with the hardware.

Thank you for your time

I have an IBM Thinkpad with a Pentium 4 processor and Windows Vista (all up to date as well as drivers). 2 weeks ago, i had it hooked up to my Mistubishi 1080 HDTV via VGA cable and it was working fine. Now, after I have hosted kareoke through a second monitor 2 fridays in a row, the TV won’t display the computer screen after the green loading bar for windows. The laptop screen proceeds onto the password screen to log in.

Out of my ten or so attempts, the last one yielded a sort of faded green line screen on the TV after the loading screen. The screen on the laptop is fine, the cable and settings are the same. I don’t understand how it can show the screen until the login screen.

Please help!

hi I have a laptop here that the lcd goes black
when rebooted it starts perfectly fine

Once used after a certain amount of time the screen randomly goes black, you still can see the desktop display faintly.

Using an external Monitor works perfectly.
My guess was that, the video drivers might be the cause but I’m not so sure

the laptop is a Toshiba Satellite A135-S4407
