Re: no power when at switch on
Sounds like the power socket on the laptop may have broken loose from the board. Very common.
If you have a multimeter, try and check the voltage ont the tines where the main battery receives it's charge, with the ac adapter connected to the laptop. That will tell a lot.

Battery chargers are wired into a boat's electrical system. Wiring the charger to a battery switch permits the charging of the individual batteries or battery banks. The switch can be configured to charge both batteries or battery banks at once. Mounting the charger in the vessel keeps the charger where it will do the most good--connected to the batteries. This is useful if you are stuck with low batteries and need a recharge. Power from a generator, shore power or even AC power from another vessel can be used to get you going again
Instructions Things You'll Need: Battery charger Battery switch Battery cable (sized) Cable cutters Razor knife Battery terminal lugs Lug crimper Terminal kit Terminal crimper Hammer Step 1 Mount the battery switch with the mounting kit provided by the manufacturer. The switch should be accessible but close to the battery or battery banks. Step 2 Mount the battery charger in a location that will be accessible but protected from the elements. Mount the charger close to the battery switch to reduce the size of the charger leads. Step 3 Connect the battery cables to the battery switch. Mount the battery cables onto their corresponding terminal studs on the battery switch. Step 4 Lay out the battery positive cable from the charger to the switch and cut it to length with the cable cutters. Strip 3/4 inch of insulation from the cable ends with a razor knife. Splice the cable to the hot wire from the charger with a **** connector and the terminal crimper. Crimp a terminal lug onto the battery end of the cable with the lug crimper and a hammer. Connect the terminal lug at the battery switch positive output terminal. Step 5 Lay out a battery cable from the charger to the battery negative terminal block. Cut the cable to length and strip 3/4 inch of insulation from the ends with a razor knife. Connect the battery negative cable to the charger negative power lead with a ****-splice and the terminal crimpers. Crimp a terminal lug onto the terminal block end of the cable with the lug crimper and a hammer. Connect the terminal lug at the battery negative terminal block post.
Tips & Warnings Set the switch to "1," "2" or "both" to charge battery bank 1, bank 2 or both batteries at once.
In this case first things you can do is check your Charger and the power cable, are they ok, is your charger providing proper voltage? Remove the battery and try switching on the laptop connecting charger only. if still same thing then i am afraid that there is some problem with *********** board.
I have the exact same problem with my old computer! The problem started after I switched the HDD a long time ago but I never got it (semi-)working again until a few days ago.I completely disassembled the computer and reassembled it again and I finally got something on the screen. I the tried to install win xp but when I pressed the keyboard the problem reoccurred. Therefore I'm fairly sure there is a short circuit or a bad connection somewhere probably on the underside of the motherboard close to the power supply DC-connector.
Dear, Remove the battery and plug-in the power cable to the laptop and then start it. If it do start, then there is a problem with battery. I m sure your laptop is under warranty. Please go to service center.
See if there is an error beep. If there is an erro beep, then change main board. Power off. Then check if RAM CPU BIOS are well-connected. Press Fn+F5 three times slowly LCD FPC LCD inverter LCD USB does not work correctly USB device cable is firmly connected into the USB ports. Test
OK people, I have this old acer 290 the battery refuses to charge so I use the power adapter but when I swith it on it may quickly flash on and then hang, turns completely off dead as a door nail. this happened all the time untill one day I left the battery out of it plugged the power adapter in and the problem dissapeared. I have not yet replaced the battery so dont know if a new battery will solve the problem when reinstalled?
