This Toshiba A70 was traded in on 23Jun2012 from an IBM T40. It had headphone jack broken and a bit slow.

I took the laptop apart and checked the inside. The headphone jack was totally broken. I went through several motherboards that I had and found one that has the same headphone jack. Using hot air rework station, I replaced the headphone jack. While laptop was disassembled, I cleaned up the fan and applied additional thermal compound to the CPU.

After assembled the laptop back, I ran the recovery DVD to install Windows XP Home to it. I then downloaded the SP2 and installed it for WiFi connection. However, when I ran the Internet Explorer 6.0 again, it was frozen under the SP2 and page displayed incorrectly. I marginally downloaded the IE 8.0 that fixes the issue. If I install the operating system, I will test upgrading the IE before upgrading the SP2.

I ran YouTube video, it was not displayed. After installing the Flash Player manually, the video displays. The screen is crisp, clear and nice. I tested the speaker and headphone jack. Both are working.

Finally, to address the slow response, I added 1GB RAM to it. I tested again. It is much faster because the original 512MB RAM is partly used for graphic processing. I tested the battery which dropped to 10% after running for an hour.

This Toshiba A70 is fixed and becomes faster after the adding the 1GB RAM. It was taken up by a lady who came with two energetic kids from Surrey on 19Jul2012.

On 20Mar2013, the lady contacted me that the DC power jack inside the laptop was broken. Besides that, the laptop is good. I picked it up the other day and took the laptop apart another time to get the motherboard out which has 2 screws to near the front and 4 hex screws at the back. I replaced the DC power jack with more solder to the secure it on the motherboard. While assembling the laptop, I cleaned up both fans which had accumulated some dust inside. At the end, I cleaned up the body again and tested to the log-on screen asking for password that I could not go further.
