    Without the battery it will occasionally power up briefly but not long enough to load up.(10 secs max.)



    No warranty so I guess it will be a new board.

See if it will power up without the battery. If it doesn't you're doomed unless you got a warranty service active. Laptop power supply circuit is embedded into its mainboard. This is why a warranty is needed because mostly they just swap the mainboard.

I have a HP/Compaq 6510b laptop computer and it will not turn on...I have the charger plugged in and the only thing happening is the green light periodically flashes...Is the battery bad?


IF the battery is bad the charge lndicator on the laptop will flash (But not periodically) it will be a constant on-off-on-off..... Best check would be to remove the battery completely and use the adapter/charger power supply only. If it still does not turn on then you either have a bad power jack connection or a more serious motherboard problem. Also is the green light flashing on the adapter/charger or is it the charge/battery indicator on the laptop?

HP Pavilion zv6000: USB ports are inop. USB port on rear of computer works fine. USB port on left/front will power my flash drive, but the light stays on constantly. The flash drive is does NOT show up in...


After reading the description, I think you need to try updating BIOS and latest device drivers for USB. Because USB are getting power on that means there would not be any fault to from the motherboard.

So please try updating latest BIOS for your notebook.
If you can provide me the product no for your notebook and the operating system which you are using currently then I can find the one for you.

Otherwise you can also do the same.

Type in the product no. on www.hp.com. Then go to software and driver download page, select the proper OS and search in BIOS ROM pack available for your notebook.

I hope this will help.

I plug it up and green power light blinks off and on


If the main power light only comes on very briefly then there is a strong chance the power supply is or has failed..

If the fan on the power supply only spins very briefly after it has been switched off for a couple of minutes then that too is an indication of a bad power supply.

Either way that can be easily checked at most computer stores in a matter of seconds. new PSU's are also relatively cheap and obtainable.

If it is the PSU purchase one with a higher rating than your current one.

EG if yours is a 350 watt PSU then go for a 400 watt or higher.

Hope this gives you the information you need

Yes i sounds like you Battery has failed, remove the battery and turn on the laptop using only the power cord, if it works w/o the battery then the battery is truly dead.

Advent laptop 7079 suddenly has no power, power adapter light is on


Is there a power indicator light on the laptop? If so , is it on when the adapter's light is on and plugged into the laptop? If not, try gently moving the computer end of the plug on the adapter while it's all plugged in. If the power indicator on the laptop flashes briefly or comes on you have an issue with a loose power connection in the laptop and need to have it serviced . this is a very common issue with laptops that are frequently plugged in and unplugged as the motion promoted lose plugs and solder.
also the laptop could be in hibernate mode and holding the power button on the laptop down for about 7 seconds should wake it.
If still no power i would suspect the power supply and aagain i would take it and have it serviced at this point.. ALWAYS CHECK THE WARRANTEE BEFORE YOU SERVICE SOMETHING YOURSELF
Post again here if i can assist you further
Please rate if this solves your issue
