My Problem

Camera would not power up. I found that the CMOS battery receptacle solder points had come undone. I tried to re-solder but it didn't work. I think the poor connection damaged something else in the mother board. I purchased a manufacturers refurbished MB on eBay for $159.00.

My Fix

Replaced the main board. . . .

My Problem

Damaged dock, slow phone.

My Fix

The repair went beautifully. Could have used stereo magnifiers, though. Did a cold reboot, then discharged to 10% followed by a non-stop charge to 100%. Had a fast phone again with long battery life.

After about a week, it wouldn’t take a charge unless the battery was dow . . .

Battery needed servicing. I was still running the original battery, but mainly on the charger 24/7.

My Fix

Followed the guide and the replacement was very easy.

My Advice

You will need a Tri-wing screwdriver. Luckily I had a frend that had one. If not for him, I would have had to delay the replacement until I foun . . .

My Problem

The original battery was so low in "health" that it began shutting the computer off sporadically at charge levels lower than 50% - the computer was no longer reliable unless it was powered through the AC adapter.

My Fix

Your battery worked very well, starting off at around 30% charge and showing 99% health . . .
