I repair Toshiba Satellite A70 and A75 laptops almost every single day and I like to work with this model. I think that Toshiba Satellite A70/A75 is one of the easiest Toshiba laptops for disassembly. Unfortunately, this model has some issues. About 90% of all laptops we repair have one of the following problems:
- Not properly grounded top cover. The laptop will shut down or lock up when you touch it around the speaker or touchpad area. This problem could be fixed by replacing the top cover assembly.
- Overheating problem. The laptop will shut down by itself without any reason. To fix the overheating problem you have to take the laptop apart and clean up the heatsink.
- The power jack issue. The laptop will not charge the battery. The laptop LED flicker when you wiggle the power jack. To fix this problem you have to replace or resolder the DC jack on the system board.

I hava a toshiba sattellite A70. I purchased a new battery to replace the old battery with about 5 min life. The new battery does not work at all. Shows full capacity but PC goes down upon removal of outlet power. Put original battery back in and ok. How can I test battery PA3383U-1BRS? How can I test the internal PC jack to make sure it is charging correctly. Current test of internal PC battery jack shows one post with more voltage than others and middle post with none.
Thanks

You guys F’ing rock! My sister is a broke student and needed some work done on her laptop.
I am in the electronics business currently and entering the IT industry in Jan so I figured I would see what I could do for her.
With your hepl, I have the computer running properly again.
Thanks for the help!~

It’s been awhile since I did my repair so I don’t remember exactly what my symptoms were when mine wouldn’t boot. But I do remember the solution. That little ribbon cable from the touchpad to the MB was not seated correctly. It’s really short and rigid and even more difficult if you have big hands. FWIW…

Stealth:
Do you have aftermarket RAM installed? If so, pull the RAM and reboot. If it comes back up, shut down and re-insert RAM and see if it boots. I have this problem when my RAM was going bad.

I disassembled my A75 and discovered one of the little gray rectagular boxes (specifically pc77 on bottom near the right side of the copper fins) was barely attached. Do you know what these gray components are? Can I desolder/resolder? I found reference to someone resoddering one of these they popped the part (overheated?).

I have the A75 model and disassembled for cleaning. And my problem is like most people on here; the system won’t boot after assembled. I had dis/assembled the laptop several times to check all connections, processor lock n secure, video card, ram, HDrive, mouse,keyboard, and even used external monitor. However each times, the power button light blinks and no boot(quiet). Maybe after few continuous pressing, the fans run and shuts off but the power light stay on. Plugin or battery only, it’s the same symptom. I read through almost all posts here but still haven’t find the exact solution. Many replies was told to secure lock the processor and I checked it thoroughly. Please anyone can help me out. And the laptop work/boot fine before I took it apart to clean.

Jack :
You said that you put in a new Hd and installed it, Then what you need to do is a complete wipe that writes zero’s to the Hd and then do a fresh install if the recovery disk is not installing right, so any info on the drive should be saved, so hook it up usb to another computer, transfer the info and do a clean zero wipe with WD Zero wipe that can be found on Hiren’s disk. This happens alot when reinstalling or trying to redo windows over on recovery from OEM
dealers cause it doesn’t read right.

I put new hard drive in A75. Used recovery CD with no problem, but some issues with Windows XP and registry. I then did repeat recovery. Now recovery runs to about 25-30% and computer turns off. I tried recovery CD at least 5-6 more times with same result. With Recovery CD out, I get error that I can not access drive.
This happened in past and I brought to local repair shop registered by Toshiba. They used software in shop that fixed recovery. Shop closed for weekend. Any ideas?

Hey have a question for you. I looked through the posts to see if any had to same question to save time but alas I seem to be the only one and since you are the expert let me see if you can help me.
I cleaned out my A75 about 8 months ago from all the dust to fix the overheating and it seems to have worked great. All the sudden about a week ago the lcd screen has been twiggin out. The display kinda flickers or the image shifts or seems lighter colors than it should be. If i adjust the Top of the laptop(start to close it or adjust the height) the flicker/ shifting changes and sometime fixes it. I guess I might have a lose connection but I find it odd that it all of the sudden started happening.
Please any suggestion on where to look would be helpful.
