實際上是轉軸問題誘發出C蓋D蓋的螺絲座裂損,但螺絲座的設計也是CD許多 這台筆電使用6個月後突然轉軸靠C蓋處,隨著打開螢幕會掀起來 當時人在海外,當地的客服是寄送DHL紙箱到府,使用者再把筆電寄回去保固 可是這過程發生很多錯誤導致於無法使用保固,後面再詳述 我有拆修LCD,數位相機,智慧型手機等寥寥可數的經驗 不想再等保固曠日廢時,況且做了功課後發現很多類似狀況原廠根本不保固 決定自己修,我翻閱了原廠的Hardware Maintenance Manual後著手拆檢 發現轉軸的螺絲座全裂開了: http://imgur.com/WOB6j0Rhttp://imgur.com/5g4VEadhttp://imgur.com/5YIuNEUhttp://imgur.com/wTdFnxThttp://imgur.com/vp7pfc4
我暫時不知道該怎麼處理這樣結構的問題,所以先用膠嘗試把裂開的螺絲座收緊, 施工完後,右邊的狀況有改善很多,左邊改善的幅度不大,自此之後開螢幕都得 按壓住那部位,但最後還是把C蓋左上角弄裂了。 又過了半年我終於回國,帶到服務中心,報價C蓋與D蓋各是三千多,只買料件自己換, 也是這價錢。可是給工程師換,竟然也沒有保固。也就是說只要使用者拿到手上, 使用一天/周/月再壞同樣的問題是你家的事。我很失望,只好自己想辦法修。 又再次把C蓋拆了,整台筆電像散掉的線裝書一樣擺在桌上。原本的想法是找適合的 墊片/塊,像做牙套一樣把裂開的螺絲座套住,再找長的螺絲穿過去,試過一次發現 不可行,光是找合適的尺寸就太難了。後來參考朋友的意見,使用塑鋼土並用 更長螺絲穿過D蓋對鎖。 準備了以下的材料:80分鐘硬化的AB塑鋼土,M3機械牙螺絲與對應墊片螺帽,螺絲膠, 3.0mm鑽頭兩隻,快乾 使用工具有:電鑽,鉗子,螺絲起子與扳手 原廠固定轉軸使用M2.5螺絲,以一邊三顆,其中一顆鎖C蓋的方式固定。為了增加強度 ,我使用粗一點的M3螺絲。先把轉軸葉片上的孔鑽大,耗去我兩隻鑽頭。D蓋一樣 在原螺絲座底下鑽洞。 接下來鋪上塑鋼土,嘗試填補螺絲座四周的縫隙給予支撐,觀察並避免干涉其他元件與C 蓋的閉合,這裡很重要的是,要盡量重建原本螺絲座的高度,不然轉軸鎖上後,會干涉 C蓋或打開螢幕後歪掉以及內應力等。形狀出來後,在原本螺絲孔的位置鑽洞,以便 後續鎖上。 http://imgur.com/gST0MLq
等乾了之後,先把轉軸轉到螢幕成90度位置並確認兩側轉軸為同一平面,螢幕稍微靠在牆 面上這樣鎖上螺絲,穿出D蓋部分加上墊片並鎖上螺帽。 http://imgur.com/mofTPtbhttp://imgur.com/hnUaCeihttp://imgur.com/TWx1Rm2
初步到這樣算是大概完成了,我組回來測試了開機與轉軸的狀況,後續又再一次做了細部 的施工。我發現左轉軸特別的緊澀,就是這樣往復開關後,拉壞螺絲座的,我嘗試 上了點油,希望能夠改善。 在這一切施工完後,打開螢幕時C蓋還是會些微的翹起來,我觀察發現,這電腦的D蓋,軟 得像墊板一樣,如果在完全沒有搭載機板零件的狀況下,抓著喇叭那端上下搖動,也許 就能明顯感受到整塊板子扭轉了。所以在轉軸部分補強後,D蓋的中段會隨著螢幕 翻開變形,尤其是風扇開孔那處更是斷了兩條,我又把它們用快乾接回。此外,這種 轉軸間完全由電池連接的設計,電池安裝與否也會明顯影響扭動的幅度。 目前這台機器已經回復正常使用了,我希望能夠起碼再撐一年。對於這次的維修我有幾點 還需要修正的地方: 1.一邊固定電池的卡榫被塑鋼土黏死了,雖然我有再三測試但乾掉後還是給黏到。 2.其中一個螺絲孔有偏差,導致螺絲歪著鎖, 這是開孔時沒有抓好位置。 3.螺絲的長度若能修到剛好,搭配使用尼龍螺帽與彈簧墊片,會更加完整 4.客製較大片的墊片而不是那小小的圓墊片,分散應力會更好 5.外加兩條鋁/鋼/碳纖維的補強板於D蓋,減少變形。 3/4/5點因為實在沒有時間就沒弄了,整體我打65分。散在桌上一個月的筆電終於離開, 解除了龐大的壓力。 http://imgur.com/jcxf9za
後記:Lenovo在我還在海外的其間還有來信調查,以下是我的回覆 1. The DHL delivery is not reliable. They left nothing like a notice when the delivery was not completed due to there were no one home. This is not Lenovo's fault but it did take me a long time waiting(patiently). 2. I was claiming a hinge problem. While I was waiting for the DHL box I tried google "laptop hinge problem" and the Lenovo's notorious hinge design was shown on FIRST PAGE. What's even interesting was that link comes from Lenovo's forum. 2.1 I then read that forum thread and found out there are many victims like me have their laptop sent back and being charged because Lenovo doesn't cover this failure design in warranty. 2.2 I identically know a bit of camera/cellphone/alike repair so I tried the disassemble procedure from Hardware Maintenance Manual because I was waiting(patiently) weeks long for that DHL box. When I located the issue I have to say the design is the most unbelievable thing I ever seen. I felt so deeply ashamed that I told my friend Lenovo is what they should consider buying. 3. Finally I got the box but that was weeks later. And by that time I was going for a interstate traveling. Under any circumstance I could't send it back, wait for a couple more weeks and have Lenovo tell me it's not under warranty. 4. I have to say it's a painful experience. Even doing this survey is painful. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 27.240.56.64
