アップルワイヤレスキーボードの電池が出ない - Apple Wireless Keyboard Troubled


大変だ。キーボードが反応しなくなったので電池交換しようとしたら、奥の単三乾電池が液漏れして中で固着状態。しごいても出せない。写真の丸いところを注目。ネットで検索してみるとこのトラブルに遭遇した人は結構多いが、適切な処理法の書き込みは見当たらない。もしやこの高価な製品はこれで廃棄の運命なのかと不安が走る。ダメ元で腰を据えて修理を試みることにしよう。

製品を見渡す限り唯一取り付く島があるとすれば筒状の底面側にある乳白色のプラスチックパーツだ。これを両側から指でつぶすように圧しながら隙間が作れないかと揉んでいたら、うまくパカッと外れてくれた。

中には小さな基板が鎮座していて、それを留めているのは小さな+ネジ、当然これを取り外す。次に基板に巻き込むように配線フィルムが黒い接続端子に差し込まれているので、これを優しき引き抜く。すると基板アセンブリーは左側に抜くことができる。

あとは長いドライバーか何かで中の乾電池をガンガン突いていけば、中から出てくる。筒の中に付着した白い物質はゴシゴシ削って、さらに筒の内壁を綺麗に拭き掃除する。修復は逆手順で基板アセンブリーを戻し、ネジ留めして、フィルム配線を差し直したら、新しい乾電池を入れれば良し。至って整然と作業できた。


The keyboard stopped working. As I understood the batteries were gone, I tried to replace them but the second one was rotten and stuck in the tube (look into the top photo). It was helpless. I see many users face this problem because they raise questions in the net, but I could not find proper procedures to save the product. Does it have to be trashed? Okay, let's try repairing it myself before I throw it...

The only clue for possibility I could see was a plastic part on the bottom surface, so I pushed both sides of its round surface to see if I could get a slightest space to squeeze a blade or something in, and luckily enough it came off the product almost by itself. 

Now I could see a small circuit board that was tied by a Philips-type screw. First I released it, and the second I gently pulled out the film circuit that was slotted in a black connector. Then the small assembly as a whole slid out of the tube. 

I used a driver tool long enough to hit the stuck battery: hit, hit, hit until the battery came off. You need to remove the debris inside the tube and clean it before reassembling the parts. So glad to see the keyboard is working again!

Sakura Watching - 花見2017

Everybody in Japan is excited now with blooming cherry blossoms. I went to Chidorigafuchi, one of the most popular places for "hanami" (flower-watching). Conveniently, it is in the middle of Tokyo along the banks surrounding Emperor's Palace. The street was full of visitors even on the weekday.

On Friday the 7th, I was in Nerima and checked the blossoms around Toei Film Studio. Kind of nice to see no crowds here.

On the 10th, I walked along the bank of Minuma-Tanbo area near Ohmiya, Saitama. It was so relaxing in the countryside without too many people.
