1. 幾種DELL Laptop

Laptop鍵盤的鍵拆換,D620/D820不同:https://www.youtube.com/watch?v=QCYOiK9QP08 實際用鍾表扁起子或指甲由上兩角挑起即出,重裝按下。即便D620也有多款鍵盤,有的鍵帽要拆的僅剩黑塑料,其餘機構裝好後在加蓋帽。

1.0 Latitude 3550, 811812402/130664266, 4CPU 8GRAM, 1366x768, Dell Wireless 1707/Qualcomm 9565 wifi b/g/n但檢測不到,參考: https://forums.linuxmint.com/viewtopic.php?t=304393 我是重新編譯kernel為5.13.1並使能CONFIG_ATH9K_*實現的。Samsung ssd f/w update:https://www.youtube.com/watch?v=uRPLL2fDYa4 

1.1 D620/630(64bit):4/24/2006, Core Duo如T2400 1.83G L2=2M 32bit,Core 2 Duo如T7200 2G L2=4M 64bit性能提高35%可DIY替換,SODIMM DDR2 CL5 533/667M 4Gmax(分別在鍵盤下和背麵槽蓋下), 14.1"XGA1440x900(D15輸出頭),SATA-150, 1G lan/802.11, express card 34mm, 串口,4/6cell battery 14.8V, 19.5V 3.34/4.62A power adapter; RAM改容量後會顯示信息要等才彈出選項可按F1繼續:https://www.youtube.com/watch?v=CaeKW4kVRA0 http://www.dell.com/downloads/us/products/latit/dfamily_docking.pdf 驅動:http://en.community.dell.com/support-forums/laptop/f/3518/t/19443652 

後蓋打開有WWAN即手機類無線網口,有GSM,LTE4G等多種標準,取下電池可見SIM插座。這兩者均非標配。

1.2 D820:4/24/2006, 僅Core 2 Duo支持EMT64,其餘是32bit(XP貼紙),CPU 1.6-2G, SODIMM DDR2 CL5 533/667M 4Gmax(分別在鍵盤下和背麵槽蓋下), 15.4"WXGA(x,D15輸出),SATA-150, 1G lan/802.11, express card 54mm, 串口,6/9cell battery, 19.5V4.62A power adapter,其餘類似D620。

TRIM. eSATA和CDbay盤均可啟動。E6400的主要差別是DDR2-800M,2008推出,Core2Due 2.26G,Intel GMA 4500MHD。

E6410喇叭:右端微聲,左端聲小,耳機無聲。BIOS檢測聲微(啟動BIOS檢測在彩條後輸入N可聽見聲音)。下述為更換視頻,覺得可以隻由前麵打開,右側喇叭線剪斷重焊就是: https://www.youtube.com/watch?v=jmMYjhF92m0#t=3m28s
CMOS電池:https://www.youtube.com/watch?v=Wi5m8F-KIM4#t=20s
E6410 sleep不能複原。DELL此類問題特多經年。一個辦法是刪除/禁止任何O2Micro驅動。在Control Panel的Storage下,或Administrative Tools?Services (Local, Extended Tab), I noticed the following: "O2SDIOAssist" chugging away. I set the service to "Disabled" and rebooted. 但我的機子並無此項。
. In the search box, type troubleshooter, and then click Troubleshooting.Under System and Security, click Improve power usage.
. 最後發現Hibrate可複原,sleep不行。禁止所有sleep,lid設為hibrate,power button設為shutdown,加屏幕延時。這樣,長時間不用時和蓋即關機,再按電源按鈕可恢複現場。改WIN10後問題基本解決,但google拚音熱鍵時不時無效需鼠標點擊。

1.7 Dock

D-Dock has 4xUSB,PRT,1G LAN,stereo & SPDIF,VGA & DVI.

E-Dock少了SPDIF,多了Display port/HDMI,eSATA(可啟動)。其中EPort pr03x單個Display port/HDMI,pr02x(E-PortPlus)有兩個,最新的還有USB3:http://sjcblogs.sanjac.edu/its/files/2012/04/E-PortPlusUserGuide.pdf  http://sjcblogs.sanjac.edu/its/files/2012/04/E-PortPlusUserGuide.pdf 

1.8 WLAN & WWAN

E6410 WLAN是6300agn可改7260/8260ac,但前者有三天線後者二:http://www.legitreviews.com/upgrading-an-old-dell-latitude-laptop-with-the-intel-7260-hmw-802-11ac-wireless-card_135084 驅動https://downloadcenter.intel.com/product/75439/Intel-Dual-Band-Wireless-AC-7260  要觀察速率,Control Panel|Network and Internet|Network Connections再點擊wifi。https://downloadcenter.intel.com/product/75439/Intel-Dual-Band-Wireless-AC-7260 注意E6410是mini-PCIe接口用7260HMW,台式主板多用M.2接口型號為7260NGW;兩者都是2230即寬長度。港奸有把802.11n標為802.11ac賣的。

E6410 WLAN的左側(後蓋打開)是WWAN即手機類無線網口,有GSM,LTE4G等多種標準,SIM插座在電池下麵。這兩者均非標配。E6410 WWAN是full height Mini PCIe 30×50.95mm,WLAN是half height Mini PCIe 30×26.8 mm,接口是一樣的。

1.9 維修

CMOS電池:  http://youmeit.net/post/1637.html 先卸LED護蓋,再翻轉鍵盤,去掉擋在紐扣電池上的電纜,拔出電池電線。卸護蓋時由右至左,先撬開右側。護蓋上下銷子需往後方(鼠標方向)取出。鍵盤上方兩側有兩個螺絲,卸下後鍵盤往前方(鉸鏈方)移除翻轉。這時可見紐扣電池。擋住電池的電纜,左側插座卡向上翻轉90度即可取出,再拔掉電池的接線即可更換。

電池報告:搜索cmd,左點擊選admin運行;Win10下powercfg /batteryreport,W7下powercfg -energy;打開報告文件有設計功率與全充下功率值,如6410設計為94.5Wh現在還剩32Wh。電池Q&Ahttp://www.dell.com/support/article/cn/zh/cndhs1/sln128667/筆記本電腦電池常見問題?lang=zh 官網http://www.ecpow.cn/DELL-laptop-battery/ E6410電池http://www.ecpow.cn/DELL-laptop-battery/Latitude-E6400.html  https://www.800pc.com/dell-latitude-e6410-replacement-laptop-notebook-battery-111v-7800mah_p45555.html https://www.ebay.com/itm/Battery-For-Dell-Latitude-E6400-E6410-E6500-E6510-PT434-Laptop-Power-Supply-us-/253106679861  

口令重置:啟動計算機,按“F8”選Safe Mode,電腦進入安全模式;選管理員帳戶進入命令行方式,鍵入:net user 看用戶,再鍵入:net user <用戶名> <新密碼>待命令成功完成;重新啟動用剛設置的用戶名和密碼登錄。

ebay上AKE express/eSATA卡支持PMP: http://forum.thinkpads.com/viewtopic.php?t=117104 也有express轉多扣USB3可用來接駁USB3口外接硬盤。

2.1 X1 carbon 20HQ=Gen 5 Kabylake

RTC battery 01HY008:CR2016 https://www.ebay.com/itm/112957954766 

鍵盤進水壞了一個充電口,另一個還可用。不知何處燒壞不值得修。

鍵盤進水後,需立即按住電源鍵5秒使其關機,再拔掉AC插頭,將水由鍵盤下方倒出。而後可以打開後蓋取出電池,將機子放在暖氣口上烘幹。

2.3 T440P

https://webdoc.lenovo.com.cn/lenovowsi/new_cskb/att/106695/ThinkPad T440p用戶指南V4.0.pdf  書含錯誤代碼。機子左側有mini displayport和2xUSB3口及四合一讀卡器,右側2xUSB2可配置為alway on使睡眠時仍能對手機充電,電池倉內有SIM卡槽。合蓋後thinkpad的i上點LED點亮/慢閃/滅表示正常態/sleep/hibrate-off。後蓋打開後左上為WLAN/WWAN卡右下為硬盤。電源為3.25A,有電池時2.25A也可。F7雙顯,F8Fn+ESCwifi,Fn+ESC啟/停Fn鎖定,Fn+空格鍵啟/停鍵盤背光。點擊鼠標板右下角為右鍵,點擊左半區為左鍵。滾屏可用雙指在鼠標板上滑動,或按鼠標板的點狀條的同時用指點杆,還可類似手機作縮放;觸摸屏不如DELL可靠但靈敏度稍高。可用手機4線帶mic耳機。

用聯想20V2.25A時供電不足,我有舊的圓頭的買了方頭的adapter結果偏小,可用DELL 19.5V的加2.1/5.5圓頭再配方頭用。用3.35A電源沒問題。

3. SONY VAIO PCG-GRT100:

原版是XP,現版是win7中文旗艦,顯示已激活。沒有audio,ethernet驅動。看是2.2-2.4M P4 CPU,XGA,RAM是PC2100 266M DDR,最大1G,已裝768M。硬盤最大80G,現裝60G分了兩區。有1394,DVDROM,USB2但啟動選項中沒有USB。Sony這個網站沒有win7的支持:https://esupport.sony.com/US/p/model-home.pl?mdl=PCGGRT100&template_id=1&region_id=1&tab=download#/downloadTab

驅動:http://www.driverscape.com/manufacturers/sony/laptops-desktops/pcg-grt100(uc)/5141 僅LAN/FWEXT即可,音頻不能用沒找著

win7 ghost未試:www.windowszj.com/win7/2167.html 

 

5. Toshiba 50HP16 TV: http://www.hdtvsolutions.com/pdf/50hp16_om_e.pdf 

HDMI2+stereo,HDMI1+LR+VGA,HD-1+LR,HD-2+LR,Video1(CVBS+S)+LR,Video2(CVBS+S)+LR;HD VideoOut+LR+SPDIF+coax audio. 建議配置:BlueRay=HDMI2,PC=HDMI1+LR+VGA,DVD=HD-1 or Video1-S+LR。

6. eSATA
eSATA是沒有電源的,到eSATAp或稱eSATA-USB combo才有。後者把USB放在下麵,當然就有5V了,兩側是可選的12V,通常desktop才有。

How to check if my eSATAp port provides 12V power?

To know if your eSATAp can supply 12v or no, check the existence of P12 and P13 pins inside the port as it showing in the pictures. Also you can probe P12 and P13 using DMM(Digital multimeter)

7. 網線和RJ45 http://en.wikipedia.org/wiki/8P8C#Types
如果沒記錯,電話線接頭RJ11/6P6C隻用兩線,網線接頭RJ45/8P8C複雜些,100M雙絞線是CAT5e(CAT5互擾要求低)收發各一對(餘下仍可用作其它用途比如電話或網絡供電),250M雙絞線是CAT6用全部四對來支持1G,HD的線屬於此類,但是有的未必能支持到1G,或者隻能在幾米內上到1G。CAT5是 24AWG,5e和6都該是23AWG的銅線,鋁線鍍銅如Amazon上的一些就比較差了,應當是滿足不了標準對電阻率的要求的。國產還有部分對為鐵線的。因此若想上1G還是350M的線靠譜些。 500/600/1000M的分別是CAT6a、CAT7、CAT7a線了。10GBaseT為500M,可選550/600M的線。
插頭雖然都是CAT45規格,但23/24AWG的線槽卡子有點差別,有的賣家都不知道的。通常兩頭都是一樣的接法T568A,除非兩機不通過switch/router直接對接,這時一頭為T568B收發倒反。

1+/2,3/6是100M,加4/5,7/8是1G。Spliiter的話可以wo/o,wg/g與wb/b,wb/b分別接兩口,中間這段隻要一根RJ45線,但每口限於100M。https://www.youtube.com/watch?v=yQOI_g-pA_A

http://www.amazon.com/s/ref=bl_sr_pc?ie=UTF8&field-brandtextbin=Monoprice&node=541966

2024.9更新:目前網線有,但是好的不多,CAT8多數看來不如CAT6a,CAT6a有VerticalCable CAT6a F/UTP 和 JavexCAT6a F/UTP;能直接埋地的有 069-561/CMXT和 069-565/CMXT,後者標明10G需$355/1Kft;接頭是TrueCable CAT6a


8. 路由器、共享、打印機

router可考慮Arris S34 cable modem有2.5G/1G網口各一個,主屋和ADU都用TPlink AX6000/BE3600有2個2.5G/3個1G網口。

現有路由器: Netgear 6300V2

打印機: Brother MFC- J4510DW帶傳真雙麵打,打印質量一般。J4510/J4710均可打印11x17“但後者是自動進紙。原裝墨水LC103(600頁)/5(1200頁)/7。Ebay墨水4盒$7,可加墨一套墨盒墨水$30。紙厚<=220gsm

墨盒: https://www.ebay.com/itm/391919100470

複位墨池計數:https://www.youtube.com/watch?v=Uw0JkImJdIM#t=1m20s,若出err46就必需換墨盒,雖可清洗但太麻煩:https://www.youtube.com/watch?v=_ymhMaSt51w https://www.youtube.com/watch?v=6IsmfZbJNfQ 注意:等出err 46時還可複位但稍麻煩,因固件常彈出此錯,但是複位與否錯誤不會消除也不能打印。上述兩視頻是同一件事,墨池清洗烘幹後還要盡量用吸水紙吸取左側外露的薄毛氈上的墨。

9 雜項

9.1 耳機接線的不同標準
目前2.5mm接頭很少,絕大多數是3.5mm,但由最初的單聲道、雙聲道到附帶麥克風,後者接線較亂:
http://forums.wpcentral.com/windows-phone-8-guides-how-tos/249287-note-headset-standards-omtp-ahj-apple.html
就 是說有兩個標準,早的Open Mobile Terminal Platform (OMTP) 和American Headset Jack (AHJ),後者又叫Cellular Telecommunications & Internet Association(CTIA),apple用CTIA。

Lenovo L24q-20 Datasheet 最後買的這個,功耗37-41W用2.25A電源,hdmi 1.4、DisplayPort 1.2 。現屏幕隨機黑不知何故。

9.3 鍵盤/鼠標

PS/2鍵盤/鼠標接線一樣,DIN6的1345是Data/Gnd/+5V/Clk。後期兩個DIN6合二為一,1345不變例如鍵盤,26作為鼠標的Data/Clk。Female接腳如圖,Male的腳號奇偶反轉。IBM二合一鍵盤的1345=白黑紅棕,鼠標的1345=綠藍橙黃。

9.4 其它

PL2303 driver:Ebay買的USB to TTL,原廠最新驅動不能用,舊版可以:http://dl.pconline.com.cn/download/827570.html  

USB3修複:Transcent USB3不被Win7識別或格式化,下此軟件修複:https://www.transcend-info.com/Support/Software-3/ 

HP Compaq DC5800 SFF: VGA/DVI,PRT,USB, 

DELL BIOS:新版WIN10下不能直接運行例如E6410A09.exe了。需要用rufus生成一個DOS U盤(下拉文件類型選DOS),將exe拷入其中,由USB重啟在DOS運行該EXE。

powercfg /batteryreport這個命令在admin的CMD窗口下運行。如果電池充電正常但檢測不到,需在control panel下刪除ACPI的電池程序,再scan即可恢複,並可檢測到電池。
