Question about Compaq Computers & Internet

Power Hi my Compaq Presario M2350EA laptop will not power up plugged into the mains nothing same with the battery even though battery is fully charged. Up until yesterday it powered up just a few mins on battery alone before cutting out, whilst connected to AC Adaptor it would power up for anything from a few mins to maybe an hour or 2 before cutting out losing power. I ve been on HP Website followed instrutions did battery test and reported battery in good health. used only AC adaptor with battery removed it powered up before cutting out after a while, i updated BIOS to latest as it suggested then everything was fine it worked both from the AC adaptor and the battery for hours, i turned the laptop off a FEW times starting it again with no problems the tried swithching it on today and nothing please help

    I had this problem with mine, inside the laptop there is a power extension block that plugs into the motherboard i replaced my power extension block at around 25 pounds from ebay, as for the battery cutting out that also needs to be replaced as its dying which means it cannot hold the charge, if you leave your power cable in after you replaced the block it will stay on. hope this has helped

It sounds like a mother board problem since you upgraded the bios and got different results. Try plugging in the adapter and warming it up. Will the computer run without the battery? that will also let you know if it's the battery.

My initial thought was that your AC adapter may have a heat problem or failing after a while. Wrap it in plastic and put it in ice and see if it lasts longer. If you have the same problem there are other issues going on in the computer power system.

It sounds to me that the battery is not connecting to your computer. Is it possible that the terminals have been damaged? Or some other issue that is disconnecting the battery from the computer?

Presario M2000 no power or LEDS


That is very possible, but make sure it is not the power supply charger, and remove the main battery to see if you can get power, bad batteries will often load down the power supply, if this works replace the rechargeable battery.

Why does my compaq presario v2000 battery always drain even while plugged in?


If the battery fully charges and lasts in normal use without the charger plugged into the laptop, then this clearly indicates a problem with the charge circuits in the computer, unfortunately this is built into the motherboard.

BATTERY is charged, but will not work without being plugged in


Your battery is old and worn out, even though it indicates as fully charged. The battery capacity is practically zero. Rechargeable batteries have a finite number of charge and discharge cycles.

You need to buy a new battery if you wish to use the laptop without connecting to the mains.

Compaq v2000


you would have to pull down the laptop if you can. there seem to be something shorting out the 14.v battery connection allowing it to discharge the charge from the battery when off. if you can get the motherboard exchanged for a new one thats you first go, because the problem is def the motherboard.

No power


Do you know if the other battery you tried had any charge in it?
If the battery was charged then it will not be a power jack or adaptor problem. As far as changing power jacks it is not for the faint of heart. I have done several with success on them all but it is not easy. If you are comfortable with opening the laptop go ahead and check all the connections on the inside. Sounds like a motherboard problem

Laptop shuts off when unplugged, battery is fully charged


Chosenone, Even though the battery meter shows it fully charged I doubt it?s correct. Over time rechargeable batteries loose their ability to store power. How long depends on the battery manufacturer and how well you treat it but you can consider yourself fortunate if your battery lasts three or four years. Beware of people who suggest you take apart your batter to bypass the safeties or replace old battery cells. Defective or improperly handled batteries can overheat and cause fires when you least expect them. Let us know if you have any more questions and please don?t forget to rate this post.
