Hp laptop 9720us screen wont brighten or dim. last week my screen went blank brought it to a shop they changed the inverter and also some cable connection . works fine just not quite as bright as before . It is about 1 yr old I've changed power settings and nothing happens .i've tried changing default monitors and nothing changes. I've made sure I've updated the bios. I have also tried the fn+f7 and f8 key and nothing happens. I try to run in with and without the power cord and nothing . before it would dim on battery power. now its as bright as if I was on battery power. could I have a bad inverter ? I dont want to bring it back to the repair shop and get charged for something I could have done .. I have updated drives I've done a HP health check and it say everything works fine and latest drivers installed. the brightness is constant and I'd like to be able to adjust if for different situations .. can you help

You got the wrong inverter fitted - i'm sure your unit requires a sinle lamp inverter and they have cheated - putting in a generic lamp inverter and branching togeather the wires to accomodate the single plug thus reducing the available volatage for the lamps - this is why it's dim - correct part is 431391-001 Display panel power inverter - For use with single lamp display panel

I have internet service through the cable service on my laptop and want to connect it to the tablet without losing it for the laptop


cable internet ?? if so then you have a cable modem at your account location , now there are a few different types of cable modems , and you may need your cable provider to help in answering what kind you have , but based on what you stated u want to be able to do , your going to need a device called a router , some cable modems have these built in and some need them added out board to them , but anyway you need a router to be able to do this , after your sure you have a router , then resubmit your question on how to add a device to a router (or your cable provider may do this 4 you ask them!) and myself or one of the others that know how to do this here will then reply with how , we will need the exact model of router you got to be able to do this

I had a similar problem and I had to "Delete Volume" when in DIsk Management. I then had a choice to "Create Simple Volume" which I did, and then a wizard created the correct partitions and assigned a drive letter to my external drive. Everything was them OK.
