My Hp530 turn off suddenly when i connect it to Ac poewr. When just i move it or touch Ac power cable sometimes it turn off.
My battery not charge at all. So if i disconnect power, laptop turn off.
should i buy new battery to fix this problem? or something in hardware?
Get a power charging adaptor from HP (if a smart adaptor) or a generic anywhere that matches your spec. Your device is doing what mine did, but in addition mine beeped softly as a warning of failure. Being a smart adaptor, I had to order one from HP, a generic won't work.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

make sure the battery posts are shiny clean and the terminals are tight
moving the terminals on dirty posts is corrupting the cpu program in the ECM
so try this
make sure the battery posts are shiny clean the terminals are clean and then fix them tight
use a scan tool to reset the ECM / CPU program and see what happens
This could be an AC adapter problem.Use another same rating adapter for teating.Check your ac adater volt and ampere at output terminals using a good quality digital multimeter. If OK, check the battery also. Then only suspect motherboard and power jack. Hope this helps
Hi Stephen, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12.5 volts or better after charging.
3. Hook up battery positive cable, then with your multimeter on the milliamp scale connect one lead to the negative battery post and the other lead to the ground cable. Meter should read 3 milliamps or less, 10 milliamps with a radio, 15 milliamps with radio and CB. If your meter reads higher you need to isolate the circuit by pulling fuses and circuit breakers one at a time and observe meter for drop in aprerage then get out your test light and track down the short in that circuit.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v while cranking replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor.

Turn the cable-modem off.
Unplug the AC poewr to the cable-modem.
Turn the router off.
Unplug the AC power.
Reconnect the AC power to both the cable-modem and the router.
Turn the router on -- this off/on sequence should "reset" the cable-modem and the router.
If the router still does not work, replace it.
If the cable-modem does not work, get RoadRunner to replace it, if they want to keep you as a paying customer.
A questions are to be asked here. Does the laptop work when connected to AC power supply? If yes does the battery charge when connected to AC? If yes does this turning off happen when running on battery too? Please answer these questions so that I can help you with the diagnosis.
The problem lies with the power supply system either in the power adopter or inside the laptop. When AC power is plugged in, the system shows that the battery is being charged (Yellow Light Indicator switches ON) but practically niether the battery is usually being charged nor the computer is being run by the AC power. Its a little bit of energy left in the battery that keeps running you computer for some time and as soon as the battery is discharged the note book shuts down by itself.
However, the Taskbar battery indicator gives the correct picture of battery charge and the charging process. Better rely on that.
Its a hardware problem pertaining to power supply and charging system and doesn't have to do any thing with Mother board, RAM, Hard disks or other hardware installed in the PC.
Do tell the above details to a repair workshop man to rectify the problem.... Best of Luch
The reason why your password is still re-curring after removing the CMOS battery is because when you were doing so, some of the cables supplying power to the Board were still plugged. So before using the CMOS removing method, first make sure that you have disconnected ALL source of power supply cable from the Board, then remove the CMOS Battery for a few seconds, and re-insert it. It should work like that.
a simple power cycle might work. Take out the battery but keep the ac power connected. hold the poewr button down for 1 minute. then hit the power button again and it should poewr back up. If this doesn' t work. iyou said hte battery light flashes so the problem isnt the battery..the problem might be hte ac power adapter..if you have a warranty this would be a good time to call them. Try the power cycle first though this fixes the problems lots of the time
