Re: v25 laptop will not turn on from battery power
The problem associated with Laptop not being able to power from the Battery, even if the Battery is new, can be attribute to the mainboard charging Electronic. The charging electronic in Mainboard is perharps defect. If your laptop still have warranty, this is the best time to change the mainboard.If not, seek for a qualified technician to check the PC, run the system, make Bios Update, and have the mainboard checked.

Is it charging? Does it Fully Charge? When you say "not holding a charge", how long are we talking about? Minutes, Hours? Battery life depends on what your doing and what is running and other factors, Some aftermarket batteries aren't very good. Inexpensive batteries are cheap for a reason.
It will because when you unplug the Power cable, it will automatically switch battery mode. When in battery mode it also activates a kind of Power saving mode by default. Thats why it seems dark. Now if still want to brightness then remove adjust the brightness level while the laptop is on Battery Mode but i must tell you, your battery backup won't last too long.
well your laptop should stay on when you take it off of your charger if its charged. Usually when someone has the problem it means the battery on their laptop is no good. This usually happens when you let your laptop die and lose all its power from the battery this can really damage your battery. Thats the only thing I can think that happened. Your probably going to need to get a new battery. I hope I helped you.
Have you determined the problem correctly?
The fault maybe the power adapter or the power plug that connects into the laptop's power socket rather than the power socket on the laptop.
Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. The power socket is soldered directly onto the motherboard, there is no wiring required. If you cannot DIY then I suggest you get a quote first.

Turn upside-down. Remove screw in the centre marked KBD.
There are 4 screws running along the back. Remove the 2 inner ones.
Lever up the keypad with a small screwdriver - Careful not to disconnect the ribbon underneath.
Undo the 3 screws along the strip above the keyboard and remove the strip.
VGA connector is next to the power button. Check it is pushed down firmly.
One way to make sure the system is still working, remove the Batery, then plug the power adapter only and turn the computer back on, normally if the laptop goes into Hybernation mode and the battery is low on power this can happen. If that fixes the system then you can do a safe shutdown and re-install the battery and turn your laptop on and it should come on, the fact that you mentioned this has happened before makes me believe it is Hybernation issue. Good Luck.
