M.2 SSD(M.2 Type)추가하고 나사로 고정한거에요. 나사는 별도로 하나 구해야합니다.

if the laptop's cooler was dirty and was overheated for long time, then may be the a second chip (not cpu) was on the verge of a problem. So when you disassemble it, the damage was caused by the minimum pressure on the motherboard when unscrewing. This is a scenario. Try to disconnect the display flex, check both connectors and reconnect it to the motherboard. Also try with one memory placed in different slots. You may remove the battery, the power supply and the raund battery inside the laptop, wait about a minute and replace it again and try to power on. Ιf the first scenario applies, then things are not good. To diagnose this scenario, you can apply some pressure on the chip with your hand and turn the laptop on. If the display is ok, then this is it.

@@computerrepairservice2654 thank you for the quick response🙏🙏 i tried a lot of things i replaced cmos battery, drained excess power, cleaned motherboard with alcohol finally recieved image when i hooked up an external monitor. All laptop functions works perfectly except for its internal display. Lcd light comes but screen remains black no bios no windows can i try anything for this problem? Thank you so much again 🙏

that's probably the first thing i said. This is the partially graphics chip problem (working external monitor, but not internal), caused by the overheating. You can, AT YOUR OWN RISK, heat the vga chip with a heat gun at ~300-340C degrees for about 15-20 seconds and 6-7 cm gun distance over the chip. Before you do it, you will remove ram and cpu. After let it cool, replace the ram and cpu and try to power on. ATTENTION!: after that procedure the display may work again, but for absolutely unknown time. ALSO, your motherboard MAY BE TOTALLY DESTROYED. If you do it, you take all the responsibility for the result!

@@computerrepairservice2654 thanks for the detailed response each time appericiated🙏 I dont have equipmant for the reflow and frankly i dont have guts and talent for this procedure. I will go to a professional after this point. But thanks again for the video and responses 🙏 Not my first rodeo though. I butchered my other laptop for fan cleaning before so its time for me to let go poor laptops😄

Probably this ssd is incompatible with your m/b. Try to reinstall it again, otherwise you should choose onother ssd.

First of all, i am professional and not amateur and I've disassembled thousends of laptops. Secondly, maybe you should watch the videos more carefully, because, I don't forget anything neither skip in the video exists. On 27.45 I reconnect the power jack connector and on 20.30 the power button flex is reconnected too. Also, the thermal paste is applyed on 16.15 and I inform you that there is not only silver paste on the market. Also I've no benefit from these video's, so I really don't care about your downvote! Finally, If you can do this with less "hard way" and "easier and safer", make your own video and let us comment it. Have a nice day!

@@computerrepairservice2654 I am indeed too fast with power connector, it's accessible from back. The keyboard cable can done more easier and safer. If you did indeed a lot laptops, why did you not know you can perfect fine lay down keyboard and connect the keyboard flatcable? How come you didn't it in this video two times, by disassembly and assembly? You are trying keep keyboard up with one hand, makes it looks not very nice and can have some risk you can bend or damage the cable. I guess this is first time you disassembled this type laptop. Then i can understand it a bit. Every laptop is different in assembly. I know from some laptops i have here, you can almost flip over keyboard and lay down (upside down) and disconnect or connect flatcable without much problems. There are more videos for same type laptops, and others did the right way. The silver paste change itself is correct. I only pointed out not every user here has silver paste in home and want only clean the fan. They can skip remove cooling piece and only remove the tape to access the cooling fins.

i dont know why you want to place the cpu from your old lsptop on to the L855 laptop, but if,as you wrote, the L855 support 3 gen i5, then it must be incompatible to the 2450 cpu, which is 2 gen. Generally, the cpu is not broken so often. Also, may be your old laptop's M/B is faulty.

Thank you for your quick reply. I have told by technician that my old M/B L850 is broken so i bought new one which sent old M/B photo, spec and cpu photo. Now make me confuse on the casing put label cpu use i5 2450m. And i checked chipset SLJ8E, which same spec. And chipset with l855. At that time i think l850 used chipset Hm65 but after checked the chipser Hm76. The problem for me if i buy new chipset i5 3340m or 3360m. I'm afraid the M/B is broken for L855. Can you inform if the cpu i5 does not support to M/B, we can look only adaptor led and power led are on, no blowing fan, blank screen. It is i want to make sure before buy new cpu i5 3 Gen. Thank you

check the connection wires of the fan. may be some wire has'nt connection (e.g. wich is responsable for RPM). Also check if the heatsink applies well on all the chips. it's difficult to see, but try. you can apply the thermal paste, place and screw the heatsink, and then remove it again and see if the thermal paste was pressed correctly on all the surface of the chip.

@@computerrepairservice2654 Thanks Tried it all just about I may have damaged the motherboard someway...

​@@computerrepairservice2654 Hey Buddy that's what it was...The fan plug on the motherboard had a prong/pin for the blue wire broke,And luckily,I was able to solder the blue wire to the broke prong/pin....Doesn't look the best,But got it working...Thanks for trying to help..Take Care

do you mean the rose mat? it's from a new motherboard packing

Thank you very much. I want to clean my laptop but can't find an ESD mat locally. I think I'll just use the rose mat.

I don't remember the exact model, but may be it is in some my older reply. I think that all the 100S models would have the M2 slot. It is not so difficult to open your laptop and see.

i guess im asking randomly but does anybody know a trick to log back into an Instagram account? I was dumb lost my account password. I love any tips you can offer me.

@Tanner Emery Instablaster ;)

@Marco Davian thanks for your reply. I got to the site on google and Im trying it out now. Takes quite some time so I will reply here later when my account password hopefully is recovered.

@Marco Davian it worked and I actually got access to my account again. Im so happy:D Thank you so much, you really help me out !

@Tanner Emery glad I could help =)

As i see on several sites, your model is not upgradable. The max supported ram is 2 GB

@@computerrepairservice2654 oh ok ty for answer

As I see on the Lenovo's site, it supports max 4 GB DDR3L.

May be deactivated. Look at the right-bootom corner in the notifications area. The bluetooth tab must be blue. Or you can download and install drivers from the Dell's website

Same issue here, no drivers on dell's website, only with external module I could use bluetooth
