SOURCE: HP 210 mini. No

It is possible that it is the cable, but it is far more likely that the backlight in the screen is out. Obviously, with how new the laptop is, this is likely a manufacturing defect. If the laptop is under a year old or covered by an extended plan through a vendor, I'd recommend taking it to them or calling HP. If not, replacing the backlight on a laptop is typically expensive enough that it makes more sense just to replace the Netbook.

SOURCE: I have an HP G62 225dx that shows a cracked screen on the display. When I hook up an external monitor it does not display correctly. Does the motherboard need replaced?

Actually this problem is due to the problem in Graphics Card. you should take your laptop to the chip level technician to fix the graphics card. if that is not solved then you should replace the motherboard.

SOURCE: when i switch on my hp 4420s laptop it display gray screen but when i attached it with external monitor the monitor works fine but lcd of laptop does not show any thing

Ahhh..the HP problem. This is a common problem and one that I am currently experiencing. The long and short of it is you will need a new motherboard or a new computer unless you are comfortable digging into this. I have two HPs with this problem and I am currently doing a reflow on this. I will keep you posted on how it turns out if you keep this thread going.

SOURCE: hp probook screen is white but monitor work

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

No power, will not turn on.


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:http://www.ifitjams.com/lappower.htm

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

My hp dv4 have vertical colored lines on my lcd screen about 1.5 inch width on the rights side of the lcd screen.. can this be fix? how?


If you are lucky, this may be down to a loose vga cable connection on the back of the screen, or at the motherboard.

First eliminate the possibility that t may be graphics chip related by seeing if the laptop will work on an external monitor without the banding you describe. If it will, you will need to remove the laptop screen and see if the connection there is tight. Check also at the motherboard end (remove keyboard and switch panel)

If it is tight, then suspect that the screen is beginning to fail, look for a replacement.

If the monitor shows a similar pattern, the issue is with the graphics chip ( common problem with HP laptops)

Motherboard is defective & needs to be replaced with a new one.
You can find a replacement motherboard by searching on e-bay.com with the motherboard's model number. This could be found under the RAM.

Hp pavilion dv4-1220us overheating then shutsdown


Sounds like you need to take it in for repairs, clean outs and/or replacements.

This product is known for it's heating issue and power consumption. Maybe the fan is starting to wear out and it's affecting the rest of the system. I would suggest checking the warranty on the system, if it is no longer valid, then I would look for a local tech in the newspaper.

Loose left button mouse on an hp dv4-1120us


If only the one button is loose then touch pad assembly probably will require replacement. This isn't a big job but usually involves opening the case. Two screws and one connector and button it back up. If the laptop is new you should have this covered by warranty. Cost of the part should be about $30-$70 as well as labor.

If you are lucky you might just have a loose fitting button that you can snap back in to place. With the laptop off try to gently push/wiggle the button down. It might pop back into its mounts. If this works (slight chance) then it might work normally for a while and pop out again. It won't have fixed the wear that let it come loose.
