Won't turn on after assembly

1. You most probably have switched on 'Num Lock' mode on your keyboard. Tty to switch back to the 'normal' mode by pressing 'Num Lock' (NumLK or similar) key or Fn+NumLock (depends on your notebook/keyboard model). In the Num Lock mode on the many notebook keyboards pressing U (not V) will produce 4 and / is located near the space, so may be you keyboard have mapped space key to / sign in the Num Lock mode or you just mistyping (you didn't specified the particular model which is mandatory for such a questions).

2. Some transient software or hardware failure. Try to switch your notebook off then on. Next try to fully cut off power - take off PSU connector and take off the battery from the compartment, then take them back.

3. If above advices will not help, thus your keyboard seems to be some kind damaged. If this is the case, most probable reason is internal line short circuit by the liquid (water, etc), leaked to the keyboard. You can order a new/used keyboard from store/ebay or try to fix yours. Some notebook keyboard (pulled off from the compartment - look for service manual or video for your model) are relatively easy to disassemble, and clean mechanical parts and the button matrix films with alcohol or some similar solvent to to clean off short circuiting oxides and eliminate issues.

Most notebook and some desktop keyboards are difficult to disassemble and assemble back due to the multiple (decades) plastic rivets used to assembly all the layers together. Once you disassemble and separate layers to clean, thus You shall restore rivets some way upon the back assembly (new rivets, soldering iron or some glue). On other hand the desktop keyboards are easy to disassembly/assembly and clean in most cases. Most of them are assembled with a few decades of the standard screws.

Next problem you can experience upon disassembly is a pads and traces corrosion. That's why any electronic devices should be powered off immediately, then disassembled and cleaned ASAP once the liquid leakage occurred. Drying is not enough solution and cannot guarantee some oxides didn't covered parts inside will not [partially] short circuit and/or corrode these parts especially upon current will flow again. Moreover this will most probably occur upon a time once liquid reached some important device components inside. Fixation could not be done later in some cases once corrosion have fully destroyed some components. Damaged traces and pads on the keyboard films which made of some conducting composite with aluminium or graphite powder, could be fixed with a special expensive conductive adhesive (glue). Being an experienced electronic engineer, I have successfully fixed a few boards, but this work is very precision, complicated and time consuming (lost a few hours for every case and was forced to asm/disasm tens of times to precisely sharpen pad layers).

I would remove the battery, etc, and then disassemble the keyboard. I would bet the ribbon cable connection from the keyboard/mouse pad is loose or gummed up. The symptoms are of a poor connection causing 'misfire' of the nerves.... Remove the keyboard, clean the ribbon connector, and re-assemble.

Hi!Looks like the cable which connects the screen to the motherboard is loose. Although nothing seems to be broken, the disassembley is still required to put the cable in it's place. If you decide to do it yourself, you can find lots of guides and videos in the net. Here is one, for example: Disassembly-Guide">http://www.scribd.com/doc/3534195/Motorola-v3-Disassembly-Guide
Hope this helps!

Hi, try this get the key pad changed , it could be damaged becouse of liquids on so on ad this can make the keys stick Another thing Fash the phone (reinstall phone operating program) ie memory chip (EPROM ) could be corrupted .



good luck

replaced the flexcable on the phone to have it fix

Do you have any display on the outside? If not you may have a bad cable between the top and bottom half of the phone. Has the phone been wet at all? Has it been dropped hard?
Oh most importantly is it still under warranty?

If you like i can take a look at it for you just let me know if i can help!
Good Luck!

Hi tfish,

The first thing I would do is find a buddy with the same or similar RAZR, and try swapping batteries with them. If this fixes the issue, get a new battery under warranty, or grab one off of eBay for next to nothing.

it could be two problems. one is the battery, clean the connections with Alcohol, or place a small piece of paper between the case and the battery to push the battery down more towards the coonector. second problem could be your key pad flex.

My phone developed the same trouble............ Removed battery and SIM and blew dry air into anyhole I could find, put it back together and has worked ever since.

Thanks for the tip

Hi There, My friend you may have gotten a faulty phone, and i'm quite positive that u did...The phone may have suffered some water damaged and it was not listed by the seller. Maybe u could send the seller back a nice message. Hope this helps. Sam !
