Why won't a samsung 1.5tb connect to dv4 - HP Pavilion dv4-1120us Notebook

Yes, this would indicate a graphics chip issue if both the external and lcd screen are flickering. The issue may be as simple as cleaning the unit from inside, replacing the heat sink, or replacing the graphics card or motherboard depending on if it is integrated.

Hi David,
First thing you can do is a ipconfig /release /renew
to do that, go to:

Start>All Programs>Accessories>Command Prompt.
Once thats open, type in ipconfig /release
note, there should be a space between ipconfig and /release and renew
your ip address should come up with 0.0.0.0

Now type in ipconfig /renew
remember a space between ipconfig and /renew
You should see an ip address of 192.168.XXX.XXX or 10.10.XXX.XXX something like that, depending on your network settings.
if you do, you should be able to get on the internet.

If you see an address of 169.254.XXX.XXX
Then it would be best if you powered off the Modem and the Router.

First turn off the Router, Next the Modem.
Power back on in reverse order and see if it is able to connect then.

If all that fails, You can reset the router and see if it will connect then.
You should have a reset button on the back of the router.
Remember once the router is reset, you\'ll have to redo the security settings.

Hope this helps!

Computer does not boot up The problem maybe the RAM, it could be faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

Have it checked in service !

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:

Check ALL cables, try another cord/charger. Change AC outlet. Is the battery in? Is it charging? remove battery, Has the laptop been pulled by the cord damaging the AC jack?

It doesn't start at all. Can you see something on screen ? Have you tried to remove the battery and charger and press power buton for 30 seconds ? And put back the battery ? Try also to check RAM Memory

Maybe it's the charger or dc jack that was broken. Just test with a known working adapter connected, see if it charges, if yes, then your charger is broken, while if not, then you have to resoldered your dc power jack.
