Toshiba Satellite A505 usb ports fell off inside. how are they held on? how to fix?


This info is about replacing a Harddrive in a Satellite A505, but I wanted to show you what is entailed in order to access the USB ports in order to repair, or replace them.

Page 2, Step 18. (You can enlarge the photos by clicking on them)

NOTE*
ALL power removed from the laptop! AC adapter (Charger), and Battery. Buy and wear an ESD wrist strap, connect the alligator clip to a good ground source. Average cost is around $3 to $8.

Use a multi-compartment container for the various screws, mark each compartment for where the screws came out of. DO NOT mix them up.

Trying to replace power plug how does laptop come apart have all screws out cannot get it apart


Hmm. Are you sure that you want to go any further,
i.e., I recommend that you STOP and take it to a qualified technician.

The power-plug is soldered to the motherboard;
so, you'll need "good" skills at using a soldering-iron,
if you wish to reattach it.

Did you lift-off and remove the keyboard, taking care to not damage the "ribbon-cables" which connect it to the motherboard?
There could be additional screws under the keyboard.

What manufacturer? What model?
Have you looked at the manufacturer's web-site, for downloadable documents, such as a "Service Manual" for it? That manual would describe the necessary "disassembly" steps.

How can i repair the power cord plug slot on my toshiba laptop it wont charge it?


First check voltage, using a meter, at the plug coming from the adapter. If all is well, then you have to tear the laptop apart piece by piece to get to the wiring of the plug. If you finally get there, look for broken wires, burn marks, etc.. If the cord is good, plug it in while torn apart and check voltages where the wire solders into the motherboard. If something is amiss, there's a bad wire that needs replaced. If you're still having problems, and feel adventurous, retouch the solder connections on the mainboard where the wires from the power plug connect to. If it still isn't charging, it might be a bad battery or motherboard. Either way, it's not that easy to fix (except for getting a replacement battery)

My toshiba laptop crashed and will not turn on,no power.my charger works but goes off when i plug into laptop.please help?


It is possible that the jack behind the laptop where the power cord plugs into may have broekn loose from its solder that holds it in place on the laptop motherboard. Inspect the connection to make sure there is a secure and tight connection. If there is significant "wobble" after you plug in the power cord to the back of the laptop, you need to get the power jack re-soldered onto the laptop motherboard, otherwise a short may be occuring everytime you plug the power cord into the laptop thus causing your power supply light to go off.

How do i change the cmos battery a toshiba a215s7422


The cmos battery used on the A215 is the soldered type. It is a small battery soldered in a small bracket on the motherboard. You have to disassemble the laptop down to the bottom case. Once you have removed the palmrest you will see the battery in its holder in the middle of the motherboard. The solder has to be softened to remove the battery and another soldered in its place. Below is a link to the picture of the motherboard with the battery in the moddle of the board.

My laptop is a toshiba satellite P25-S526. I cant seem to get the power supply to charge the battery. I have replaced both the battery and power supply and those were not the problem. why wont my...


If you have a volt meter measure the power coming out of the power supply and make sure the outlet is good that you are plugging it into.

Try resoldering the connection on the circuit board where the power supply plugs into it. There may be a loose connection or a crack in the board that you could jumper around using a short piece of wire soldered around the break.

Toshiba Satellite P105 S6124 Power goes off. Jiggling electrical cord at base of computer gets it back on but when it's moved, it goes off again. Someone looked at it and tried a new cord. Determined...


First, the power cord connects to the Power Unit not the Motherboard, so if jiggling the wire causes the fault, it is either the Power Supply Unit or just the plug and wiring that the power cord plugs into.

If you must open the casing, try replacing the Power Unit, but the best solution is to get a computer repair person to look at it.

If you pull the unit apart and start poking around in there, you will almost certainly blow something up with static electricity (and then maybe your Motherboard will need replacing!). Note The voltage of Static Electricity (which you probably can't feel) is THOUSANDS of times higher than the Voltage that your computer components runs on. For comparison connect up a Mains Supply to a 12 volt globe and see what happens (and this is only 10-20 time higher than the required voltage.

Good luck.

Toshiba satellite p30 133


possibly memory chip or hard drive failure,
swap ram chips around to see if that fixes it .

if you have the ability, try the drive in another pc,it will not boot fully but you will be able to tell if it is working ok, else it looks like a service on the cards.

good luck
