Guest frank.lui Posted October 5, 2007 Report Posted October 5, 2007 I need some advice. Yesterday I pluged my Mini S to mains adapter (original) for recharging. Because I palyed a bit of overclock befoe that, I decided to switch off the phone before charging so that the overclock can be reset to original. This morning, I found the phone was dead. There was no sign of charging. All indicators are dead. The phone cannot be switched on. I took off the battery and left it for a while. Then I put it in. The phone started and showed O2 logo. Then the whole screen just faded off. And the charging/power indicator flushed couple of time as 'red' before screen turned completely dark. I used multi-metre to measure the battery and got 3.2V. I guess what happened was I forgot to switch on wall plug so mains adaptor over-drew the battery. I know there is a hot discussion about this overdrawn issue, as below http://www.modaco.com/Warning-Battery-Chargin-t233233.html But I do not know how to do it. Can someone give a tip? There are 6 electrical contact pads on battery. Which ones I should go for? Using the phone's mains adaptor or car battery as someone sugested? Cheers
Guest frank.lui Posted October 5, 2007 Report Posted October 5, 2007 Well, it's Friday afternoon. Experts either work hard in the office or diving in pubs so no one gave the tip. I told myself the battery is dead so why not do a DIY? What I could lose? (1) First found a tunable DC adaptor and sent to 6V. (2) Connected to the battery, with a multimeter to monitor voltage. The voltage started from 3.2v and increased slowly. (3) After 2 minutes, I was a bit fade up with the progress so I change the output to 9V. Battery voltage increased much quickly. (4) When voltage arrived 3.9v I was a bit of nervous. I wanted to save the battery not making a bomb. So I stopped. (5) Put the battery back to phone and switched on. (6) O2 Logo...WM Logo....no fading off, good sign. I connect PC' USB cable to the phone and the orange indicator was on! Bingo! (7) After the phone booted up, it showed battery had 29% power. Then I change to Mains adaptor and it continued the job so it should be not a faulty. Hopefully this accident did not cause permanent damage to battery.

Yes, some time phone doesn't start to charge after battery went down, USB charge will not help, not enough current. I tried regular power supply and after an hour it started.
Guest Swampie Posted January 3, 2008 Report Posted January 3, 2008 Yes, some time phone doesn't start to charge after battery went down, USB charge will not help, not enough current.

What I found with my old Wizard when it was completely drained and wouldn't appear to charge via USB, was to just leave it connected for a while and do something else. Came back and it turned on fine - must have been charging even though the charge light didn't come on.
