[SOLVED] 100% Repair Of Laptop & Desktop Motherboard

[Chris56000]

power lights blink and the notebook beeps 4 times

Hi!

Can anyone point me in the direction of dismantling instructions and any manual with schematics for two Packard-Bell laptops please? Both are Easy One Models, one type N1550 (550MHz) and the other an Easy One Silver N1600 (600MHz).

Both machines operate off batteries but will not charge or operate off mains! I've seen a Mitac manual which has circuit/schematic diagrams in it but not (obviously!) for the machines I have! Is there a Mitac clone to these P-B machines?

Many thanks,

Chris Williams

repair the burnt chip on laptop motherboard

I have amilo 1667g laptop and i had problems with video card(mxm i ati x700), after having hot air on it solved the problem for about 3 months), now i think i have inverter problem, some times the screen goes blank and see things behind very dim, or flickers sometimes but some times the screen is tottaly black. About the total blank screen and freezing(have to reboot to gain access the computer goes black and does't normal shut down), all the symptoms seems to be the inverter but the total black screen?can it also be caused by the inverter???
Thanks in advance

Hai nnannos
When you say you solved the video problem with hot air, try the same remedy here too. Coz the boards may have started having dry solder all round due to passage of life. You didnt mention the life of the LTop. Good luck

presario v2000 hang setup is starting windows

Hi all !
I have ACER Aspire 5630 with no backlight. I think it's the inverter, but I tried to see signal in 7 pins connector and I see that on #3 first times I turned notebook on, there was a digital signal that disappeared pressing close-notebook sensor, while now it's always at 0 V. Is there anyone that know where this pin connect in mainboard or what can I check ? I was wondering if damage was caused by me shorting with oscilloscope probe this pin with adiacent +19V pin. Sensor is ok. Tried it with multimeter. Thanks very much and have a splendid day

laptop gpu diode temperature

I have a Dell Inspiron 5100 that seems to have a Motherboard issue.

When pressing the power button the CPU fan spins and hard drive spins up but I have no video. Hard Drive LED seems to quit flashing quickly. Will these give beep codes? Im more use to working on desktops. I've replaced the video with a known good card (have another 5100 that works flawlessly with it).

Any ideas where to continue looking?

Its not too expensive and can do what much higher priced machines do. It can be used to desolder/solder any smd components, BGA ICs like the north and south bridges, etc. Do check it out.

dv1000 hp schemetic diagram

Hi

Thanks for sharing all your experience!
I've got a HP NX7010 laptop that functions perfectly, excepting for the power button that doesn't work. From what I've been able to gather, the tact switch on the motherboard is a SPDT type, roughly 6x6mm in size. Currently the only way to turn it on is to short out 2 of the leads where the switch is connected. My problem is that I cannot find a replacemente switch anywhere - I've searched high and low, found many similar switches, but no the one I need. Any idea on where I might buy one or what I can use as a replacement?

Thanks!
