Tutorial for upgrading acer 5920G to GT240M and successfully installing nvidia drivers
Ставить такую видеокарту, которая стоит как три таких ноутбука, очень глупо
I have 7010 DT when i press power button right still solid in white and fan running but not booting up. sometimes shut down . and sometimes booting tp after 10 to 12 mins of wait. when bootup no issue, but when i shut down its give me again same fault booting up very late also when turn on no keyboard light when keyboard light on its boot up quickly. what is issue?
Somehow, it's was a loose connection . Thank you for your work.
Thank you so much! that was the problem with mine, been using it for video editing (wrong laptop choice) for 10 years :o Avoid buying Ideapads, choose ThinkPads instead
😊
Hello, Very heplful video Did you only connect the +tive output from the converter to the screen fuse, and the negative output of the converter to a ground on the motherboad. Or did you isolate the screen power completely and run both positive and negative from the converter to the screen. Ta Jim Hallett
Hello thank you for your video Can you explain exactly what you did ? I mean where to solder exactly What resistor do you use on the converter ? I’m Not English I didn’t understand when you talked about it It would be even more helpful thank you in advance
Hello, can u tell me specifically where to buy this gt240m? I want to fix this laptop but I want a solution with the least mods.
which country its from australia? if so i need to see you buddu
Now HP is a crap
How can I fix it for long term ? 😊
Hi. What is the part number of the DC-DC converter that you used? Thanks.
Hi, is it possible to connect GPU to this laptop? I mean can type-c port give us this opportunity? I can’t find information about his port, is it Thunderbolt or something else?
hi, can i use this type of keys to activate on a motherboard without key integrated in bios?
sure
What do I use to make a BIOS Dump?
you need an eeprom programmer... i usually use the TL866II+
what is the stuff did you put? before heating
It's a gel
Gracias. Suscrito
خیلی عالی، hp 450 g4 ۹ بار چشمک میزنه دلیلش همین موضوع است آیا؟ 11:40
Hello sir I have a hp pavilion laptop When i turn the power button on the capslock first blink 3 times slow and then 2 time faster Also i tried to replace ram and removing battery but it didn't work for me. What are your thoughts on that what could be the problem?
I have the same issue. Without RAM it beeps, and with RAM it doesn't boot, just keeps restarting. Tried different PSU, CPU, RAM and disconnecting all non-essential components. Tried adding a discrete GPU too, same result. So far I've reprogrammed the smaller chip, but that didn't solve it. Are both BIOS chips necessary? Getting the bigger one off the board might be difficult for me, and I don't have a clamp for that size.
I desoldered the 16 pin chip, programmed a new .bin into it and soldered it back on. PC came back to life :)
Do u maybe sell the original gpu card of this laptop? In case it works.
Of your acer 5920g have some problem with gpu i have to tell you acer 5920g support some gpu from the other brand Asus & hp You can using some nvidia card from asus g50v 9700m gt/gtx 260m (maybe you must modify radiator or using correctly copper for heat) Or radeon you can using from hp Hd 3650/hd 4650/hd 2600 pro its working well Some card will e run but you have to modify driver Brand asus is Gt 210m Gt 240m 9650m gt Also you can upgrade using same brand (acer) 9600m gt ddr3 from acer 5930g but you have to mod bios first Or 9650m from acer 8930g.
What's your opinion for so many people having display problem with this laptop? I bought a new gpu card and it didn't work. Can it be something else?
What gpu do you bought?i had to tried gtx 260m from asus g50vt and its running well but you must modding some radiator im using a copper and stock radiator
Hi. I have same problem in HP Probook 470G1. Is the schematic same as of 450
i need bios file. pleace
it would be great if you could tell me the series of the GPU fan, thank
I have similar issue with R556L. On the battery blue sceen after 1-2minutes. I've bought new battery, and the same resoults. Battery is charging, I can leave laptop on battery in bios settings and it will can work hour like that, but on windows there is blue screen. Newest bios, new hard drive, fresh windows, no drivers, or with drivers, - still no changes. Blue screen on battery with information that gereral issue occur (no specific driver is pointed or code). I will check your sugestion, that only when battery is low -you had filckering. I thik it can be the issue with Super I/O or with charger ic, or there is a semi-shorted component on the board, or the issue is with uma (integrated graphics) or with discreete (nvidia graphics) I have boardview and schematic so I will start to didding and I will do an update here later.
How did U found that last capacitor? i have the same short on asus tuf fx505du ,on alc233 caps on pin 25 and caps on pin 41&46,all are on +5VS. Is it safe to inject voltage,if yes how much?? asking because this motherboard goes for cca600 euro,i dont wanna burn it...
Hello, I have a laptop E1-570g-32214G50M, but I press the power button, then I see a blue led light, but it doesn't work I have a screen black, the fan starts for a few seconds and then turns off. if I connect the power supply, there is a red charging light. You think it could be the bios. Can you help me , The mainbord is LA-9535P rev 1.0 CPU intel i3-33217u intel graphics 4000
Hi, i have a laptop e1 572g, but i press power button, then i see a blue led light, but not working or have a screen. Everything is black. No light anymore. I deplug battery, 15 seconds power press without charger, but it doesnt work. Can you help me
But isn't this a ddr2 laptop and a gddr3 GPU - wouldn't this massively bottleneck? I would have guessed using a ddr2 GPU would perform better even if it's not as good
Nope you can upgrade the cpu using x9000 Ram 8gb Also a better sd similiar like samsung evolution etc Windows 7 64bit And gt 240m i play gta 5 and the result is very fantantic for me.
how did you got 8 gigs ? I'm only able to go to 4+1 GB @@rajacomputer9822

19v line had a short. A burned capacitor and a the burned battery power switch was replaced
Hi Thanks for the video, but could you explain better what you did? Yes i've a dc-dc converter. but how to wire them? A schematic would be nice. Also which pins did you disconnect on the video-motherboard connector? All 4 pins from the left? Why
thanks, you remove the first 3 pins that are the main voltage to the lcd (19v form jack or 7-9v from battery) then you add a step up converter and take the input voltage from the battery directly to the back of the lcd, so that the voltage is always 14v
you need to disassmble the lcd and connect the cable directly to the lcd main voltage
Hi, can we add more RAM space to this laptop?
No, you can’t. I have this laptop and already disassembled it a couple of times. Memory soldered on motherboard, but you can add nvme M2 SSD. But, unfortunately, only one disk
So the problem is solved by removing the first 3 pin from the Lcd power supply?
not so easy, you remove the first 3 pins that are the main voltage to the lcd (19v form jack or 7-9v from battery) then you add a step up converter and take the input voltage from the battery directly to the back of the lcd.
Can’t you you solder the battery power ( with step up converter) directly to the 3 pins you separated from the charger power supply ?
Thanks for the Video really informative
thanks heating the cpu with heat gun worked for me 👍🙏
where is solution?
did..... you see the video?
@@ntechlab8357 The video misses crucial detailed information. You Have a great solution which can help lots of people, but the tutorial is just not the best :-(
Hello, I have an Acer V3-771G with no image. I tried the display with another board from a similar laptop, it worked. Then I've swapped the Bios chip from that other board. Unfortunately it didn't work. The display remains black. Can it work, to swap the Bios Chip from a similar laptop? (The two boards have the same Rev. Number, yet they are not identical. One has 2 the other has 4 Ram slots. Also the soldered GPU is not exactly the same.
hi, bios should be the same, check if chipset and gpu are the same, it helps if they are the same. also it is not recommended to swap bios, you should program one, and preferably with clean ME region, you may also have problem woth the gpu, you can try and thansfer the board to UMA
hi!, you can use this "method" only for uncrypted DMi areas... on Lenovo bios there is a protected area (LENV) that is storing DMI information (like the windows serial) ... in this case the job can't be done with an HEX viewer, i wrote a small utility to de-crypt that is called BIOSdump2license
Wow, just tried it, awesome tool, thank you very much
if i could add something it would be the option to copy the key form the software :)

Hello, Can you please tell me what menu appears when you press the Novo button (OneKey Recovery button) on a *functional* laptop? Does it have the Normal Startup option? Reason: My Lenovo U330p's power button has become prone to getting stuck pressed. I am considering switching to the Novo button for normal startup instead, but as far as I know, not all models have the Normal Startup option in the menu.
Thank you for putting this out there, confirms what I was worried about with my own laptop.
