ok my computer battery died (don't know how) and if the wire (which gives the computer power) is moved it shuts completely off.sounds like a shortage but the randomly black screen is annoying :wall: . i can be doing anything or just have my laptop on and the screen turns black.any help please

 

 

 

remember when it turns black the laptop is still on

Does it happen when you're doing something or when you idle? It could be that Windows has turned your power settings so that if you don't do anything for a minute or so it turns your screen off. Not usre if this is possible but it might be worth checking. Just select power options under the control panel (assuming you are using windows, not something else).

it happns when i am idle and when i am doing stuff

Well having a [bleep]ing annoying title (all caps) isn't going to help you any faster, ugh.

 

 

 

 

 

 

 

When you say that a random black screen pops up what do you do to get it to go away. I mean, does it force a restart? Do you need to move the cord? Or do you just move your mouse or something a bit?

 

 

 

And, when you say wire you mean the power cord right? I was pretty certain that even if you are plugged in the laptop is still using the battery as it's source of power, which in that case I'd say get a new battery.

yes i mean power cord and it forces a restart how do i install a new battery

If it's like any other laptop you should just have to buy a new one from your manufacturer and then just pop the broken one out and put the new one in.

Just to make doubly sure before going to spend money on a new battery, try running the laptop with the power cord in, but no battery. It's saved me a pretty penny in the past.

 

 

 

Other than it being a possible power cord or battery issue (which can be partially determined by the above suggestion), there are a few more possibilities.

 

 

 

Next time it happens, get close to the monitor and make sure the room is dark, and check and see if you can faintly see some applications. This may indicate that your back light is dying.

 

 

 

A good way to test if it is your lcd dying is to gain access to an external monitor for a bit. If you have a desktop computer and the correct port on your laptop (most laptops in my experience do), just disconnect the monitor from the desktop (after it has been shut off completely, of course), and plug it in your laptop, and try to set it as your main screen. If the laptop runs without error, your monitor is to blame. If the black screen still occurs, you may be looking at a memory problem.

 

 

 

It could also be your memory refreshing. If you have a lot of programs taking up memory (like another user here who had something like 8 svchost instances running), this could be a plausible issue. Try to close extra programs running, or in the worst case, try a reformat (after backing up documents of course).

 

 

 

Also, I can't remember if you put it in or not, but if your laptop is relatively new, and is still covered under warranty, back up any important documents (with CDs, DVDs, Thumb Drives, External Drives, whatever), call the manufacturer, and try to get a replacement.

 

 

 

Alright, that's all I could come up with, so I hope it helps.

It sounds like you have 3 faults on your laptop:

 

 

 

1. Obviously the battery needs replacing. Batteries are considered consumables by the manufacturer. No way round this but to replace it.

 

 

 

2. The power socket on your laptop has a dry joint, this is what is causing it to shut down when you wiggle the cable. This is incredibly common on laptops and it's one of the things we repair the most. Basically it needs soldering, but this is not something you can do yourself as you need to completely dismantle the system and take out the motherboard.

 

 

 

3. The inverter is dying, this is probably what is causing the screen going black intermittently. Yet again, this is pretty common on laptops and is quite easy for a technician to repair. See here for more details.

If you have a lot of programs taking up memory (like another user here who had something like 8 svchost instances running)

 

 

 

8 svchost processes is completely normal..

Yep, you're 100% correct. SVCHOST is not a program by itself, it is used by other programs to connect to resources such as Windows Updates.
