I purchased a HP 2133 Mini note book computer shortly after they went up for sale. I rarely used it because I bought it when I needed to fly. Now the computer will not boot up. No hard drive activity, black monitor, no Wi-Fi light. It is dead. I check on the HP site for possible solutions. Followed all of their suggestions. Reinstalled the original 1GB memory unit (I ordered a 2GB upgrade). Even bought a new hard drive. Still no boot. Did a little message board searching and found out that this is a common problem with this computer. Contacted HP who suggested I send it in for an inspection (for a $25 fee). I believe that HP owes it to it's customers to repair these paper weight at no charge.
