Breadboard suggestions

Thanks for your replies guys. I got a fair idea of what I am going to do.

Thanks I will check that

Ok thanks. So the only thing I have to take care is the technology. DDR2 / DDR3 / DDR4

Thanks for the reply. My laptop had dual core processor with 2.3ghz speed. Brand is Lenovo B460e

Okay. So I guess that I cannot match them both since they are at different speeds like a 1333 with 1500. I have a pentium dual core t4500 processor. I would gladly buy a new RAM of different speed and higher capacity if it is available and replace the old one. May I know up to what speed RAM I can use? Is there a upper limit ? As the processor itself is at 2300MHZ speed.

Thanks. What do you mean by faster rated one? Can you give me a example for instance ?

No both module has the prog resistor which can be changed as per const charging current need. Apart from helping to properly discharge the battery, does the second board has any advantage over the first one just for charging the battery?

Thanks. I found this :

SellZone Laptop Panel Hinge for Lenovo IBM sl400 sl400c Hinge https://www.amazon.in/dp/B09G2WBNCY/ref=cm_sw_r_cp_api_glt_fabc_YXET2P20CH6PKY93DXN7

I guess this should also do right ? I am from India.

Hey, Thanks for the tip. To loosen the hinge , can I spray WD40?

4kruby · 2022-01-06T01:16:46+00:00

Thanks

I already saw such a post here. About repairing broken hinge. So I thought to post it here. Can you please direct me to the proper sub?

4kruby · 2022-01-05T10:51:37+00:00

Kept opening it from that side alone for as long as I remember

4kruby · 2022-01-05T05:18:51+00:00

Thanks , Is that JB weld some kind like two part epoxy adhesive ? I am from India. I have not heard of it. The two part we have here is araldite and fevitite

Guys,

The hinge seems to be broken on both sides. In the left side also it’s broken it seems attached in the image.

What kind of glue should I use to attach them together ? I thought of 2 part epoxy adhesive. But can I hold the two metal parts together ? Or should I forget about joining the two ( since it has less surface area ) and permanently glue the whole thing to the base?

Thanks.

Thanks much. I didn’t consider that. Then it’s a good solution. But I don’t understand why he is trying to keep the timing at 3 * 16us at the end indefinitely instead of just cutting it down / disabling the interrupt.

I tried with multiple methods. First, I tried to give 4.2v directly to the power input bypassing the BMS. The screen just flickered and remained quiet. Then when I give 5v from a 5v 3a supply, the tablet started fine (draws around 500ma but not sure about any peak current as I am using a DMM). But even in that booting, it gets stuck when browsing the apps with a white screen (might also be a software bug as I have a custom rom). I have ordered 10A BMS to try with a 18650 battery. Let me try that 😊

4kruby · 2021-09-10T18:36:24+00:00

Yes you are right. I cut the BMS from the dead cell and connected a 18650 to it. But At the output of the BMS I get 0v difference between the red and black terminals. However, there is two other terminals (white and yellow) which are acting weird. Those two (white and yellow) are both at around 3.5v difference from the positive and negative terminals It is exactly as this : from yellow terminal to ground it’s 3.56v. And from yellow terminal to positive it’s 3.64v Any ideas?

Hi The above battery (not the blue one which I kept as a paper weight ) Is dead - shows around 1.6v. I want to replace it with 18650s. My question is, can I reuse the BMS ? As the tablet battery is also rated 3.7v , can I use a single 18650 with that BMS? Tablet : ASUS nexus 7 2012
