@yoogee not sure what you mean by "doesn't charge forward" but I assume you are saying it does not charge. first off, we will need to know how old this battery is. A depleted battery will not accept a charge, not matter how hard we try. If this is a known good battery then thee are a few other issues you need to check.
First you want to check your power supply. Make sure it has the proper voltages. Check to make sure that connectors are not bend etc. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. Clean it of any debris etc. Use a few puffs of air to clean it out. If none of this works, get an ammeter and see if your laptop draws any amperage from the charger. After that, you need to check and see if your motherboard even gets power. For that of course, you need to open it up. Post Some good pictures of what you see. That way we can see what you see. 在已经存在的问题里加入图片

maybe check if the charging port is loose or dirty. Sometimes a simple restart or battery driver update can help too.

Some keys in my keyboard are not walking
由 Ayabonga Mabona 完成的
@ayabongamabona could be an issue on the circuit board for the keyboard. Remember that each key is actually a microswitch etc. that closes a circuit that will then be interpreted by the IC. A failed IC (on the motherboard) could be the issue but luckily most commonly it is the keyboard that has failed. Here is the ThinkPad L470 Hardware Maintenance Manual Page 76 will tell you how to change your keyboard. Replacement keyboards are readily available.
