Strange. The Battery, when charged, powers the computer and appears to discharge normally. The power adapter (It's an IGO replacement) shows proper voltage and powers the notebook on AC. The batteries (multiple) do not charge when attached to the notebook. No increase at all. Icon shows charging, but no increase. Pin voltages in battery compartment (from right to left, with black probe on 1, furthest right) show Pin 2(0), Pin 3(3.33v), Pin 4(fluctuates .7v-1.15v), Pin 5&6 (3.36v) Pin 7&8 (.7v) with no battery in place.
In your case it seems the charger is less than 90watts
A 65 watt charger will run a DV Series, but not charge the laptop. This is because the MOSFET Switch will not close and send power to the battery. They are usually the AO4407/4413 series on the bottom of the AMD motherboard. Or a dual mosfet on the Intel motherboards.
Back in the day they used to say, "One word.........Real Estate!"
So one word, "Power MOSFET",

Read into the above. Don't look at it superficially.
Post back in a Comment.

Joe, Thanks! While I won't know until I pull/replace the chip, it matches the symptoms.
The Power MOSFET's listed are obsolete. Of course the cross reference match examples are shown. FDS6679AZ is $1.01, while the first cross replacement for the obsolete AO4407 is 78 cents (USD) The Power MOSFET's are SMD/SMT. Surface Mount Device/Surface Mount Technology. All of the electronic components are, except the Solid Polymer Capacitors. They are Leaded. (And also the Radial termination style. Both leads come out the same end) Rosin flux paste. Don't leave home without it.............I mean use it, makes life MUCH easier. Don't linger, and burn the board. Don't go too fast though, and make Cold Solder Joints...............If you get time would appreciate hearing the outcome. Thank you for the rating! Regards, joecoolvette
Aggh! Need to have stated all along, the Mayohardware link to the Power MOSFET's shown, may not of course be the one's used on your motherboard. Just an example given for the symptoms the computer has.
Something I should have caught off the bat; Does the IGO replacement AC adapter have the correct Wattage? Example; 40 Watt adapter will not work for a 65 Watt adapter. 65 Watt adapter will not work when a 90 Watt adapter is needed.
Yes, adapter is 90 watt with correct tip/polarity.
Thanks for the mention.

SOURCE: false battery power alarm shut down
Ive had a look at the manufacturer web site but ther doesn't seem to be any driver for your model. You should be able to turn the battery warning alarm off in the management settings
SOURCE: IBM T30 - power issues
You might try cleaning the battery compartment. Makeing sure there are no damaged pins. Often times even a single messed up pin will cause this. Also this is a very good indication of adaptor failure. If you haven't allready I suggest getting another ac adapter specific to you machine. Even a substitute will casue the same issue you are now experianceing.

Motherboard repairs are often poorly done and they are expensive except for the simplest jobs like replacing the DC jack. And new motherboards are also generally very expensive. And cheap way out of this is buying a used battery charger or a used working motherboard. eBay is usually the best place to start. Good luck!
SOURCE: Strange ac cord/power issues
Hello my friend,
Try to check your battery if the is it working normal cause sometimes the battery itself has the problem its either lost contact or the battery is not charging or not normal. also try to see if the the the sensor or that links the battery to the software which is responsible to the update of charging energy is functioning normal but this is a rare possibility try to focus on the battery or the connector or power cord.
Hope this will able to help solve you problem.
If you need more assistance just reply to this post.
Thank you
Jonas
SOURCE: NEW Battery not properly charging
Batteries have electronics data that software has to get to properly charge it. Newer lithium batteries maybe different. But apparently, you have a work around for a lengthy use of the new battery.
