Replace Mother board

How do I remove the mother board?  I have removed all visible screws, but there seem to be 2-3 places that are still fastened down.  How do I release those areas that don't appear to have any screws?

How to unlock bios of toshiba portege m500

two options

1. look on the mother board for a small round battery about the size of a nickle, remove it, start pc, after start up shut down, replace battery, start up again... or remove battery, let sit for about 30min, replace battery start pc.

2. look for a small red or yellow toggle switch or button on the mother board, (should say "reset bios") push button, restart pc.

i assume this is a lap top so there will be some disassembly of the unit, not to extreme though, usualy the battery and the switch/button are next to one another and located toward the front of the mother board, and if in lap tops the battery or batteries are in a plastic covering wired to the mother board with a small connector, just unplug connector if you cant find the reset button.

hope that helps

My Laptop DV6000EU in Aug 2007. Warrenty on Mother board

it should be under waranty seeing that the motherboard is malfunctioning again. normally the hardware will go out before the motherboard and seeing that its the same problem again mark the motherboard in a nice little place with a marker to insure they are not doing a repair and giving you back the same faulty board.

Can't get to the mother board on Acer Travelmate 4011

All i can really offer for help is to try to remove the screws on the underside of the notebook. That is how i have to remove the keyboard on my Sony vaio. I cannot find anything online that describes how to remove the keyboard. But i can say when you get the keyboard off follow the link i provided above and click on the link that says "How to fortify damaged power jack connection in a laptop" This gives excellent instructions on how to repair this jack.

Or if you want to buy a new one follow this link to buy one off e-bay.

If you look on the laptop repair link it gives you a good idea about how to remove the keyboard so follow those directions as close as you can. And remember that these computers use a lot of snap fasteners so some stuff may be snapped in place and not screwed down.

Sharp actius mp30 hard drive replacement?

It is a standard 2.5" IDE laptop drive. You have to dis-assemble to mother board. Easy to do if you are comfortable with internals. You have to remove a million screws to get case apart. All visible on bottom, also internal pc card next to memory card has 2 screws. Don't forget back side hinge screws and edge screws on upper part of lower shell visible in back and when dvd/cd is pulled (2 bottom screws hold player in. The shell come apart easily little force no tricky pressure or lock taps. Where it hinges on back top side next to LCD screen lift gently straight up this is where it is most resistant. A few ribbon cables and 2 wire cables to disconnect. After lower case top is off a few screws holding mother board (arrows) needs to be removed to lift motherboard. Drive is connected to mother board by ribbon cable lift pry gently up to release it. Drive is held in by 4 screws. Good luck. If you do not want to do this just get a 2.5" usb drive. You can buy the drives and external case or by already made ones e.g. WD passport.

BTW I am looking for an actius mp-30 casing, mine has damage.

If you have any questions post to contact me

How do i remove the keyboard

Usually you can remove the panel right above the keyboard, this will allow you to access the keyboard screws. The keyboard should swing up allowing you to unplug and remove it.

How to take an acer apire 9410-2028

You'll have to remove the mother board to fix this. Basically, remove the keyboard & touchpad. You will see the mother board at that time. Remove whatever else is necessary to get down to the mother board. Hint! Keep track of what screw comes out of what hole. You'll need to know that for reassembly.
