You are in a pay zone ?There are ways, but if you are not a trained TEC for this It could cost you more than it would for a charger? I wouldn't advise anyone to chance grounding this part.This is something everyone says so and so does it? Do you think they will cry, with you when you ruin the harddrive?
There are so many things you can mess up with this act of pennywise, pound foolish.How much do you want for the PC before you fix it? There are other manufacturers; that make the same connection for their PC's.Some of them have universal connections? I know of at least two other people that thought
This is easy? Right before they purchased a new harddrive?I won't tell you their names, but I can tell
you what size their harddrives are?I would not tell you, this to buy your machine?Although a bargain
is a bargain.Sometimes you can buy you a charger used ,out of your local paper.Good luck !

Hp laptop charger 90w 463955-001 burned component


Adapter arrived promptly, but did not have a "dongle." Seemed to work well for about 6 months but then did not charge laptop battery and only worked plugged in. Eventually a computer technician friend pointed out the adapter was too light to be real - compared my original adapter it weighs about half the weight. Not very impressed and would not recommend. I have no complaints about this item whatsoever, for all intents and purposes it does everything my original AC adaptor did.

HP Compaq NC8430: Laptop does not want to charge battery


Take the battery out, plug in the charger and see if the laptop works. If it works, the battery may be the problem. Check the AC Adapter
Check to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop. Most AC adapters have a little light in them on that rectangular box in the middle of the cord that lights up when it's getting electricity. If that light isn't on, try a different outlet. Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it. If it still does not light up, your adapter could need replacing. Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.

Remove the Battery Sometimes it's as simple as a seated battery. Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection. Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement.

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 530 wireless will not pick up any wireless networks. Please help


Hi.

First ensure that the wireless adapter is turned on.

If the adapter is on and does not detect any network, reinstall wireless network adapter drivers. the drivers can be obtained using the link below.

Download drivers and software

Reinstalling driver software usually fixes the problem, if it does not it usually means that the internal adapter is defective, in that case you will need to use an external wireless adapter (USB).
