DELL 14” LCD backlight fix
EN
That screen was “dead” by meaning there was no back light. Actually, if you plug some signal to it and start, the monitor has backlight for few seconds and then - nada. Interesting, it has 2 lamps and dual controller but both lamp was tight to the one of the channels. Anyway, what my DIY fix was: remove one SMD transistor, and solder new one.
Extendet story - IC backlight controller, send signal to one MOSFET via smd transistor(removed by me). That MOSFET control the power going to the lamp transformers. I solder new transistor to the IC power supply lines. So, when get power to monitor and push ON, that transistor “open” the mosfet and here backlight is on. In that way I lost the dimm function and backlight is always to MAX but for me that is fine, because that screen should be only use for test, or as screen for one CNC project.

Toshiba Satelite AMD - notebook fix
| EN | BG |
| That machine was lightly overheating, and bad working original Hitachi drive.I haven`t any good experience actually with Hitachi drives, especially with single plate High density ones. But have to admit, i like that small board. Cleaning the fan,new paste and reinstall fix the problems. Opening - remove all screws under, ad gently open from the all side clips - you have all to state seen on the last image. | Maшинката леко попретопляше, и имаше лошо работещ оригинален диск Hitachi. С тази марка дискове интересно само проблеми съм имал, особено с тези с голяма плътност на единична плоча. Все пак ми хареса дизайна на платката и размера ?. Отваряне - махат се всички болтчета отдолу, и внимателно се разкопчава панела от щипките. Това е. |

5W led and 18650 battery
EN - the head flash light arrive as gift(thanks mate), and it was equipped with 3.7V 3.0A batteries which quite soon start to give up on “little” more use. So i decide to take my chances and broke apart one old Asus notebook battery. Inside was few bad cells but 4 at least was just fine. So, here it go. Little cut on top(the forehead of accumulator is same straight surface as the bottom) and adding little soldiering wire. Job done, and even work
