I scoured the interweb and couldn't find one :( but don't be afraid! You can tackle this without a manual. Here's how I would do it (and I have disassembled MANY laptops)
1. Unplug and remove battery
2. Search the bottom for tiny screws and unscrew them. You can keep track of these by either drawing a picture of the bottom of the laptop on a piece of paper and placing the screws where they came from, or you can set them up in a row on your coffee table so you at know what order they came out in and can recall which location they will go. All together you will probably end up with 15 tiny screws.
3. Search for more screws on the bottom, check the battery slot, check little panels, and run your fingers across the stickers to see if you can feel any hidden screws. 4. When you think you got all the screws, turn the laptop right side up and lift up the screen (as you would to use it so it's out of the way) and, with a precision flathead screwdriver, search the perimeter of the keyboard for tiny spring-loaded holders that hold the keyboard in place. Some laptops have these, some don't. If you don't find any, move on. Keep in mind that if you miss any screws, holders, or whatever -- it isn't the end of the world. As long as you take it slow, you will feel spots of resistance where you forgot to remove something and can go to take it out.
5. This part is a little scary the first time: starting from the bottom right corner, slowly start popping out the case, separating the bottom of the laptop from the 'top' of the laptop where your wrists rest while typing. It can be intimidating hearing your laptop 'pop' the way it does, but don't worry! They are just clamps that are SUPPOSED to do that! Again, go slow in case you forgot a screw. Your resistance should be coming from the edges where you are separating, NOT from the middle of the computer. Slowly work your way around until the two parts are completely separated, and those screws you missed earlier are removed.
6. Slowly lift up on the side holding the keyboard (if you found little springed clamps in step 4 you only have to lift up on the keyboard) until you can see the underside of the keyboard and the ribbon connecting it to the motherboard (along with a connector for the touchpad and perhaps another miscellaneous connection). All of which have ends to disconnect, nothing is soldered at both ends. The ribbon will be connected to the motherboard with a small 'door' that you can swing up to release the ribbon. Don't be afraid to use a little force, my first two laptops I ever disassembled i merely pulled the ribbon out without opening the door(!) The ribbons were fine, but i do NOT recommend risking that :P
7. With the keyboard disconnected and the other small cables disconnected you may now separate the 'top' holding the keyboard and the bottom of the laptop. Usually you can do this without removing the screen, but if the screen is a problem simply disconnects its cables and take it off. Note: no two cables in the laptop will be identical in either size or connection, so hooking everything back up is as simple as putting square pegs into square holes.
8. Behold the motherboard aka logicboard in all of its glory. She is delicate, but not too terribly delicate. Don't be afraid to touch her, just, be gentle. If you cannot see the battery, the holy grail, of your quest, then it must be on the other side. Start searching for screws holding the logic board to the bottom of the laptop, and remove them.
9. Remove the logicboard from its nest. It will probably put up a small fight with things poking through holes on the sides (headphone jack, VGA connector, etc). Just work them out. Like i said before, she isn't that delicate; don't be afraid to use a little force. Expect a wire here and there to get snagged. Turn the logicboard over and replace your battery!
10. Because your logic board is out of its hole, plug it into the wall set on rubber or something and fire it up once, for the adventure, to see a naked computer run. Take pictures, post online, lie to her when she sees them in the morning.
11. Reassemble the same way you disassembled, but in reverse. It is that simple!
To get an idea of what you will undergo, I recommend searching around reading a couple laptop disassembly guides. the Acer A150 and Macbook Pro should give you a good idea of the different spectrums, and a google search should benefit (Hint: google aspireoneuser and ifixit). And take a look at this picture to familiarize yourself with enemy territory before exiting friendly lines: http://cdn-write.demandstudios.com/upload//8000/800/00/3/28803.jpg
Good luck! You will learn much by tackling this beast head on. Trust me, you won't need a guide. They are only useful for pesky hidden screws that just take a little extra time to hunt down. When you start taking it apart, if you had a guide, you wouldn't hardly look at it once you started getting it open. It is pretty straight-forward.

Hi schollmd

DISASSEMBLY GUIDE FOR TOSHIBA SATELLITE A205 LAPTOP

On certain laptops, it is possible to delete the BIOS Memory by temporarily disconnecting the CMOS/RTC Battery before reconnecting it and reassembling the laptop.

Sometimes this requires almost total disassembly of the laptop.

So no damage is done during disassembly and the correct component positions and cable connections are restored during reassembly, this is a job best done by an experienced repair technician.

While yellow is a common colour, the CMOS/RTC Battery can also be encased in blue, brown, black or green plastic.

On some models the CMOS/RTC Battery is accessible without disassembly, via the Wireless Card compartment underneath the laptop.

On other models, disconnecting and reconnecting the CMOS/RTC Battery is ineffective in clearing the BIOS Memory Cache because nearby capacitors store the data if the Battery is removed. Two contact points on the motherboard have to be bridged in order to dissipate the charge from the capacitors to reset the BIOS.

The Step-by-Step Disassembly Guide for this model series of laptops can be viewed here:

If you have checked all functions as you described and a remote monitor, then the problem is the graphics card on the motherboard, in most cases the motherboard must be changed because the graphics card is built in.

Respected i have d610 the charging light blink 3 time red then green and not changing the battery


First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.
