Motherboard replacement by similar used board but no display chipset. Must have windows key embedded in BIOS.(not brand new one except 100% identical) Later on, upgraded the ram and SSD to 16/512. Replacement of battery by third party one which was not durable at all.

Generation 8 CPU, marginally suitable for win 11.(my desktop was sixth generation but was still ok by chance, no TPM 2 problem)

Old MB having 4x4G ram but 2 faulty slots, 2x4G was sluggish yet stable when running overnight. Bought a used 8G at HK 55, working alone ok and also with existing 4G ram(12G total, much faster) Would buy another 8G ram.

風扇和電腦 monitor 共用同一拖板,每次開關風扇個 monitor 都黑一黑






加個 EMI filter 俾風扇,而家唔 "眨眼" 喇。

11 yo pc can still use windows 11, clean installation, not upgraded from 10. More relaxed from Microsoft due to complaint. Mini partition has the freeware to change MBR to GPT without loss of data, a pre-requisite.

Update bios first, in reality, the 2016 version from Asrock was having TPM 2.

大燈串 24W


小燈串12.3W


個設計係大、小燈串可以串接由藍牙控制,門市卻祇有一隻 20W 牛賣,CS 回覆話燈串可接至 10M 長卻沒設計一隻大 power 的火牛去配對,一條大燈串串兩條小燈串 draws 48.6W 卻叫人接一隻輸出得 20W 火牛。

MB and PC back into service. Awaiting CD ROM to SSD rack for mounting and also another 8G ram. Power switch was faulty and latched in ON position, possibly the failure of MB. Momentary switch is required, hence the reset button being used as power switch for the time being.

Rearranging the drives and better cabling for 2 desktops. SSD's placed on CDrom to SSD racks with new sata cables(random write improved by 25%!). But some space already occupied by surplus PS cable. Better buy HDD to SSD rack as well which can be placed at lower portion of the desktops. Anyway, problem of having SATA drives with 2 cables each. NVME SSD should solve the problem by mounting on PCIe slot direct. Still cables for MB and auxiliary supplies to display card and in/out fans.

Low level format of 1T HDD, initialize, partition and install win 11 as exercise. Skip the Microsoft log in, too clumsy. Took 4 hours. Another 3 hours for backing up a SSD with 300G program/data. Very time consuming yet low expenditure in weekend.

Would need to initialize HDD after low level format as if it were new (except aging mechanically) Must choose GPT for reading drive>2T and installing win 11(not MBR) In bios, choose secure boot, TPM and UEFI(under CSM) Can return to legacy after installation.(Choose windows manager for booting) if having mixed MBR and GPT HDD/SSD.

Test an old AC for leakage prior to diy installation. Outlet pipes blanked off, valves fully open, then closed a bit by quarter turn to avoid squeeze the internal sealing gasket (a common practice) Any drop in pressure overnight. A bit of leakage is tolerated since topping up(adding) refrigerant is simple if once every few months. Use detergent to check, bubble formed not exactly due to leakage but air trapped when detergent flows.

Many types, very hard to squeeze inside the window crevice. (Maybe fitted on window before assembly at works)I put on extra flat tape, leaving the original one intact. No water leakage during typhoon especially the horizontal windows at high level.

Can try a small piece initially.

高 torque當然好,其實平時阿仔會用cordless drill開窿後就用 impact driver收緊鑼絲。
買呢支最最最主要貪平,鋪頭有三個月保養。
